Delay, KVR Developer Challenge, KVRDC, KVRDC16, KVRDC2016, Lagrange, Universal 2 Binary, UrsaDSP

Lagrange is a unique stereo delay system producing other worldly echoes using granular techniques, where each grain is from a different point in the delay buffer:

  • Use basic settings to create immersive stereo imagery with clean early reflections to give instruments a clear place in the mix.
  • Use the feedback control to transform your sounds into droning evolving soundscapes.
  • Shorten the delay time to create unusual metallic chorus effects.

Lagrange is an effect unlike any other.

Review by Bedroom Producer Blog

Demo reel

The plugin is supplied as a Mac and Windows installer to add a 64-bit VST3 file (and an AU on Mac).

If you use and enjoy Lagrange please at least try a free demo of my commercial products. Thanks.

*** Solution for issue where Lagrange validates in Logic and appears in the Plugin Manager but does not appear on the list of available effects for a track/channel. ***.

In Logic (and I imagine in some other DAWs), Lagrange will not appear on the list of available effect plugins on a mono track. You must change a mono track to stereo for Lagrange to show up in the drop-down menu of available effects for a channel. Thanks @cnriley.

Spaceship Delay

Delay, Creative Delay, Dub Delay, Futuristic Delay, KVR Developer Challenge, KVRDC, KVRDC16, KVRDC2016, Musical Entropy, Spaceship Delay, Spring Reverb

Spaceship Delay is a delay audio effect featuring classic modern and vintage sounding delays, with the following features:

  • Three delay modes: single, ping pong and dual / stereo.
  • Standard delay effects controls such as the delay time in ms and in time subdivisions, the feedback (up to 110 % !), a tap tempo button etc.
  • A modulation section acting on the delay times and the filter cutoff frequencies.
  • An attack control allowing the user to feed the delay line only when the input volume is higher than a given threshold.
  • A spring reverb modeled from a famous tape machine (not that one, another one).
  • An advanced filtering section including standard lowpass and highpass filters, shelf filters, and the simulation of two famous synthesizer filters (not these ones either, other ones).
  • A specific "modeling" section giving access to different kind of delay line and saturation colourations, featuring a bitcrusher and a tube preamp simulation.
  • A "Freeze" switch which can be used for some creative effect or to transform the effect into a looper with high delay values.
  • Post effects such as extra filters, a tremolo and a vintage phaser

It can be used as a typical delay for mixing vocals, adding some depth to drums, guitars, synth sounds, but also as a more creative effect, thanks to the attack control, even as a looper thanks to the freeze switch and the very long maximum delay sizes.

Spaceship Delay includes finally a few presets and an embedded tutorial feature, available from the about tab (by clicking on the logo in the user interface) where you can learn how to use properly the plug-in, with live tutorials, and how to do some classic delay tricks like doubling vocals, slapback rockabilly guitars, ambient sounds etc.

Spaceship Delay is free and available on VST, AU and AAX formats (32/64-bits, Windows & Mac OS X).

Roth-AIR is a mixing tool for easily adding airy, crispy presence to your audio.

This is achieved by a combination of multiband compression and gentle saturation of the highs. It enables for a stronger, more consistent presence of high frequency material and works particularly well with vocals, synths and strings.

The process is made easy by a simple user interface, automatic makeup gain and a combined function "AIR" knob.

Roth-AIR is available for free in 32-bit and 64-bit as VST and AU (OS X only) plugins for Windows and Mac.

Sound examples: youtu.be/o_kBijBvHXQ

This plugin was developed in C++ with JUCE - Big thanks goes out to ROLI for this great framework, as well as Vincent Falco (DSPFilters) and Martin Zuther (Squeezer) for their open source contributions to the community, which this project has greatly benefited from.

SoftAmp PSA

Guitar Amp and FX Modeling, AXP, Compressor, Guitar Preamp, KVR Developer Challenge, KVRDC, KVRDC16, KVRDC2016, Noise Gate, SoftAmp PSA

SoftAmp PSA is a virtual-analog guitar pre-amp supplemented with noise gate and compressor, all modeled after famous guitar gear that needs no introduction.

At its core there are 5 distortion stages. First three are based on op-amps with zener diodes in the feedback chain, while the last two are just op-amps being overdriven into saturation. They are followed by tonestack, speaker simulator and an output level control. Each overdrive stage has a distinct frequency shaping quality according to their names. See the EQ plot in the bottom right corner for details.

All stages are modeled as nonlinear filters with their outputs depending on both the frequency and the amplitude of the input signal. It gives the most accurate digital representation, compared to cascaded filter/static waveshaper approach.

In addition to the basic controls, there are two more knobs that control the speaker simulator parameters - Shape and Rolloff. With both knobs at 0, the speaker simulator is completely bypassed (for example, to be used with external impulse loader).

Giving even finer control over the gain structure, there are two more buttons - Asymmetric and Soft-Clip. The former applies to the zener diode stages and replaces the default 4.7v/4.7v zener pair with intentionally unbalanced 3.3v/4.7v pair to saturate the signal with even harmonics. The more the first three stages are overdriven, the more pronounced is the effect. See the clipping LED indicators to have a feel of which stage gets the most saturation from the signal. The Soft-Clip function applies to the two overdriven op-amps and changes their open-loop gain from 1 million to just 200. This effectively makes the transition from linear to saturated region much more softer, making the distortion less harsh and also helping the fading notes sound smoother.

The PSI Denoiser noise gate has a handy "Learn" function. Don't play anything on your guitar and hit the Learn button. As soon as the LED goes off, the gate threshold would be automatically set to your noise level. The noise gate is applied directly to the input signal.

The Squeezo Range compressor is applied to the signal right before entering the PSA pre-amp. It's a very nonlinear, but musical sounding device. It acts as both upward and downward compressor depending on the gain and bias setting. In the original device those controls were not available for user adjustment.

For further details please see the included manual.

Lord of the Springs

Lord of the Springs is a VSTi for Windows (64/32) featuring 88 voices in form of active spring systems, which a key hit stimulates as well as modwheel scrubbing.

Lord of the Springs V2 overview on YOUTUBE

As one might imagine, springs will generally create rather metallic sounds, which makes it ideal for complex glockenspiel sounds, xylophones, marimbas and so on, but the freedom granted by the features allows for a much greater variety of sounds from soft, dreamy pads to harsh percussion and other percussive sounds.

Beware, though, because it truly is procedural sound creation, potentially creating spikes when you line up the spring frequencies. I advice the use of a limiter to avoid possible heart-attacks or damage to equipment.

It also features a unique pitchbend implementation that allows only held down keys to be pitched, while sustained keys (via sustain pedal) won't be affected by it. Once a key is released, a pitch relax value controls how quickly it will return to the original pitch of the key. Once the bend key is struck again without any pitch bending, it will be tuned back to normal instantly.


  • set it high to create whole new performance styles for quick runs.
  • set it medium for almost chorus like effects when pitching toward a clean key.
  • set it low to keep the pitch bend after releasing the key.

The probably most outlandish feature is the BODY or ONE SPRING TO RULE THEM ALL, which is kind of why I ended up calling it Lord of the Springs. This one spring sits underneath all springs and stimulates all of them by what ever sound they produce. It creates an almost plate reverb like effect, which can be modified in a variety of ways, including its own tuning, decay, diffusion and- what I call- "sharpness". On top of that it has its own phaser effect with a tremolo that can go stereo and can have its rate synced not just to BPM but to actual song position for a perfect lineup with a beat, if so desired. Subtle use of the phaser can create compelling room impressions as well, which is the original reason for why I implemented it to begin with. The BODY also features a blendable SOLO mode, again increasing the amount of sound creation possibilities somewhat substantially, though, mostly in the realm of special effects.

The entire GUI design is completely procedural without the use of any images, which allows the small file size, but also allows me to go crazy with weird ideas on the fly. If only I had more time to reduce the chaos, but...

I sincerely hope you will enjoy using it, while I had to rush to get it done in time for the challenge. Once voting is over and my hopes and dreams won't be smashed to pieces (haha), I will happily resume developing further versions. Come to think of it, even with shattered dreams I will continue, because it's tremendous fun for me.

Best of luck to everyone,

This virtual instrument is free of charge. KVR is permitted to do with it as they please, of course. All other restrictions of commercial and copyrighted software apply.

Noisetar is a synthesizer dedicated to the generation of many different noise based sounds.

The generation is purely mathematical, no samples or wavetables are used, thus allowing for an easy continuous morphing from one sound to the other. Twelve parameters control the generator, moreover its output can be further shaped and enriched inside Noisetar with its two filters, a chorusing reverb and a stereo enhancer. As modulators Noisetar offers an ADSR envelope and keytracking, with seven destinations.

Using the included bandpass filter, which is tuned to the incoming MIDI notes, is also possible to play Noisetar melodically.

Noisetar is designed with DAW parameter automation in mind to tailor complex custom modulations tied to each project rather then dealing with complicated patches.

Noisetar has its own sound space, ranging from various digital noises to crackle, rattles and crepitations similar to wood fire or rain, scratchy percussions and foot stomps, with many others from the lowest booming and gurgling drones, to thin misty hisses. The quality and types of Noisetar sounds obviously doesn't cover all possible noise sounds, but most certainly will increase your noise arsenal without taking up more than 2MB on your drive.

Any musical genre can make use of a versatile noise synth. Enjoy exploring its unique sound space.


  • Unique integrated sound engine, with comb filter, LFO, AM, FM etc...
  • Polyphony ten voices.
  • Keytracking for various parameters.
  • Melodic bandpass filter with adjustable bandwidth.
  • ADSR envelope with 4 targets.


  • 12dB/octave, low pass and high pass.
  • Chorusing Reverb.
  • Stereo Enhancer.


  • All parameters can be automated inside a DAW.
  • Tooltips on screen.
  • Resizable GUI.
  • Custom colours and texture.

SnareBuzz is an audio effect plugin that emulates the wires of a snare buzzing when there's another instrument playing near.

Why do you want to emulate this effect if every engineer in the world has tried to get rid of it? Short: because it's cool! Long: because it doesn't exist in the DAW environment, it's something that we are all familiar with, and if you're really used to play live with a band it's weird not hearing it when recording instruments separately.

Do you imagine a Led Zeppelin recording with Bonzo's snare not buzzing?
"Music is people playing live in the same room with eye contact and feeling each other".

Attack and release controls that set how the snare reacts to the incoming signal, HP and LP filters to shape the sound of it, room ambience for a more natural feel, overall gain, panning of just the effect and dry/wet controls.

Insert it on the bass track, adjust the mix knob just a tiny bit and hear how these little wires bring life to your mix. You'll miss it when it's bypassed.

Malefica is a virtual high-gain distortion guitar pedal based on original schematic.

Let us tell you how we created Malefica:

Malefica Formulae
First of all we have analyzed circuits of ton of guitar pedals to design the darkest, most evil and mystic tone with unique character that would fit a wide range of extreme music genres.
After that, we have made its physical model on the tip of the pen and prepared it with most precise and modern mathematical algorithms.
Finally, our designer has added magical artwork, and that is it! Witchery is alive.


  • common output level (alias "Evil" in the plug-in), tone ("Witch"), dist ("Mist") and bypass controls;
  • 3 modes switch for the different sound colour;
  • 3 modes switch for the different clipping character;
  • additional tweak controls: pre-gain and focus frequency of tone control;
  • stereo/mono modes switch;
  • 8x oversampling switch for an extra high precision.

Modulation, KVR Developer Challenge, KVRDC, KVRDC16, KVRDC2016, lkjb, SuperSpread

SuperSpread uses multiple pitch shifters to spread a signal thus allowing supersawing any input it is given.

Besides using it on any synths it is also a handy tool to create pseudo double tracking for guitars or to a lesser extend vocals. In case of guitars, it is best applied on a clean DI recording before amp simulations.

The source code is available on github.


  • V1.1.0: Update to new JUCE version.
  • V1.0.2: Fixed latency compensation in VST3 bypass.
  • V1.0.1: Added mix control (click on GUI to toggle knob), Statically linked MSVCP140.dll.
  • V1.0.0: Initial Release.

Random MIDI Arranger

Random MIDI Arranger is a stand-alone Windows based program that can generate random MIDI songs at the click of a single button. It uses a combination of preset MIDI clips and sets of rules called 'Manipulators' to generate each instrument track. It also features a 'Render Engine' which determines song structure, track density, repetitions, tempo, etc. The results can then be exported to a MIDI file for further editing.

Features include:

  • Randomly generate entire songs in about 1 second with the click of a single 'Auto Randomize Song' button.

Fuzzed is an analogue modelling distortion plugin, using "state of the art" state-space modelling techniques to model the physical circuitry of the famous Jimi Hendrix guitar pedal and implement it as a VST plugin using the JUCE API.

Rather than simply modelling the general behaviour of the pedal, this plugin uses the circuit schematic to construct a highly accurate simulation of the pedal's behaviour, with full parametric control. This is then implemented as a VST plugin for use in real time.

Included are some analysis screenshots of the comparisons between the output of the system and the real pedal, which shows the behaviour of the VST to be highly comparable to the real thing.

This work is the result of continued development of a plugin created and submitted as part of an individual university project.

The examples show case the guitar tones produced, with an additional example showing the use of Fuzzed to add analogue distortion to a synth + verb as a return/aux effect.

Use of Fuzzed as a return effect can add beautiful analogue distortion to your sounds without losing the original tonal content.

**Update 14th December 2016**.

Added Windows 7 support.

**Update 2nd April 2017**.

Optimised performance on some machines. Changes to the circuit to improve the quality of the sound (especially for low frequencies).

BL-303 is a contribution synth with Big Love to the legendary Roland TB-303.

The BL-303 allows you to effortlessly create the iconic acid basslines, leads, and sequences.

Version 3.0 includes improved and resizable user interface, the filter was fine-tuned to sound and behave even closer to the original TB-303, a few more minor performance and sound improvements. Native support for mac Arm and Intel processors.

The sequencer part (including the slide and the accent) is handled with MIDI notes velocity:

  • Shorten the note length a little bit, so it ends slightly before the next note (like the TB).
  • Use the Velocity to control the Accent and the Slide.
  • Velocity 0 – 9: Slide On.
  • Velocity 10 – 100: Regular note.
  • Velocity 101 – 126: Accent On.
  • Velocity 127: Accent & Slide On.

Extent of the Jam: Slam is an original algorithmic drum machine design inspired by analog drum machines of days gone by. It's made to allow users to create hard-hitting snares, beefy bassdrums, and all kinds of other sounds-- with ease.

Each sound was meticulously tweaked to give you deep organic sounds with a wide range of options and settings. Close your eyes and you won't even think it's digital.

But Extent of the Jam: Slam isn't content to just emulate old drum machines. While most old drum machines only had two levels of velocity (accented and non-accented), Slam gives you 127 levels of velocity for each drum. And it's not just different volume levels: the velocity alters how the drums react. It also features drums not commonly found on analog drum machines such as finger-snap and tambourine. It'll even produce gnarly synth bass tones that you can play on a chromatic scale.

Slam is 100% native C++ code.

FFT Randomizer

Soundware for: ReaJS, REAPER

FFT Randomizer is a JSFX script that does spectral randomization smoothly, both magnitude and phase, to shape audio randomly. It comes with similar settings as "cloud fractal noise" algorithms in imaging software (such as the layered cloud generation) but instead of generating images, you sculpt up the spectrum's both magnitude and phase with it. In effect, it's inspired by the Diamond-square algorithm, but it is not exactly the same, as it also allows you total control over each of the layers and obviously deals with sound, not images.

Be warned, this is a geeky and experimental effect, you will probably not understand it right away or find instant uses for it in your music. It's intended to design sounds or instruments and add some life to the basic noise types we're all used to, and shape up any sound you can think of randomly to make it more interesting. It's also an effect for perfectionists who like to fiddle around with sound in more bizarre ways.

This is not your conventional FFT randomizer/processor. Most of those FFT-based tools deal with FFT bins directly, for example by randomizing them all on each window, which doesn't have many uses in my opinion, because it's dependent on the window size for the underlying effects and limited to that "geometry". It uses mathematical models that are completely independent of the bins. The only time it affects the bins is at the end of the processing chain, when they are simply interpolated and smoothed based on the model calculated prior. Think of it as having a mathematical model that gets applied to pixels on an image with values between pixels interpolated — instead of randomizing each pixel itself, which is what standard and simple FFT tools would do. The latter is obviously worse, because its effect depends on the resolution of the image itself and is very limited in effect (it only makes high frequency noise!). As a result, the output on the sonogram can look like "clouds" if used on white noise input, but it works on any signal to shape it.

I strongly recommend that you use a Spectrogram/Sonogram to visualize what this effect does, best to start with white noise as input or while setting it up, and then replace it with the actual signal you wish to process. (for example I personally use Sonogram SG-1, an excellent and free Sonogram)


  • Filter any input sound randomly and dynamically by changing its magnitudes and phases, independently.
  • Layer-based random shape algorithm that changes with time, so you can have smooth shapes, or more noisy shapes, and have them slow or fast independently.
  • Exact and independent control over each layer, even including a spectral graph to change the layer's effect on the output, depending on frequency.
  • Special "Additive Mode" on phase amounts to have all the phases changed relative to a new "center", so the entire phase spectrum will shift, but randomly.
  • Ability to use special MIDI Program Change events as triggers to "reset" the shape and get a new one, within a time specified.

Since you're probably still confused about it and without having a video, follow the below two examples to get an idea of what it can do and start playing around with it.


  1. Use a Spectrogram/Sonogram that allows you to visualize easily in realtime (the one I use: Sonogram SG-1), insert it after this script, and keep it open (to look at it).
  2. Send white noise to the input of this script, it should show up as white noise on the Sonogram for now.
  3. Reduce the Gain so it won't blow your speakers, say set it to -20dB.
  4. You should have Layer 1 selected in the drop-down by default. Then adjust the Magnitude Range (dB) to an amount that is less than the Gain, say to 16dB.
  5. Increase the Magnitude Speed (Hz) so the changes start to happen faster, make it about 1 Hz or so to be smooth, since we're on Layer 1.
  6. You should see patterns in the sonogram on the noise! Your white noise is no longer boring and static, and it varies over time: its magnitude over different frequencies is being changed. Try play with Magnitude Contrast and see what you get! What is the difference? Increasing the contrast clearly makes the variations more sharp, right? What about decreasing it?

And remember this is just one layer, try changing the layer from the drop-down menu and see the difference it makes (don't forget to also set that new layer's respective parameters, as all of the above are specific to each layer, except for Gain). Also remember that, while white noise is a good way to see and learn how this works, and even during designing the parameters and setting it up, the script can actually be used on any input! Please don't forget to turn Gain lower if you add multiple layers with more dB range, though.

Simple Example Showcase

Here's a very simplistic example of a nice evolving sound you can generate with it by just adjusting a few parameters:

  1. Send white noise to this effect.
  2. We want to change Layer 5, so click on Edit Layer dropdown list, and select Layer 5.
  3. Set the Gain (dB) to -27.
  4. Set the Magnitude Range (dB) to 42.
  5. Set the Magnitude Contrast to 15 (max).
  6. Set the Magnitude Speed (Hz) to 0.5.
  7. Set the Magnitude Speed Modulation Rate (%) to 120.

Behold a nice atmospheric and evolving breathy texture! And so far we've only been demonstrating white noise as input, when in fact it can be used on any input. You can hear this example in the audio player. The same settings, but applied to an Octaved Supersaw can be heard in the second audio example.

There are way more things and parameters which won't be explained in this introduction. For more information, visit its dedicated page here. You can look at the comments below for a lengthy explanation if you are confused of its purpose, or read that "essay" on its page at the Closing Words & Another Example section. :)

Remember that you will need a JSFX processor that loads JSFX scripts to load it. ReaJS from ReaPlugs is free in VST format, while REAPER can also load JSFX natively. (technically I believe Cockos open-sourced the interpreter, so there could be more)

Please note that the mono mode does not work yet in ReaJS as of this time, until Cockos updates it to add fft_real, it will only work in REAPER. The stereo one works fine though so you can use it in any DAW with ReaJS, but will use more CPU, otherwise it is identical.

Lastly, because it is a fully open script with no obfuscation, feel free to take a look at it or even edit it, I tried to comment where I found necessary. Be WARNED, though, that I optimized the audio processing part for speed. If you find it unreadable in certain parts, it is not on purpose! Just a side-effect of the optimizations... Most of the math is, however, not commented, since it would take too long to explain and I'm not good at explaining math (I used Computer Algebra Software to devise it from ideas anyway).

Kontakt Microtuner provides a generic Script designed to be used in any Kontakt Instrument with a spare script slot to add a Microtuner. 300+ Scales are included and Scala files can be converted using an online converter.

The script is provided as a preset which is added to the user Preset/Script folder and then available from the preset menu of each script slot. The Microtuner Patches need to be stored in the Kontakt Installation folder as this is the only folder that is accessible from both Library Instruments and non-library instruments for some reason. Unfortunately the pictures folder is not available from library instruments too and so the script must remain ugly.

kalipheno is a sci-fi themed sample pack created using a variety of sounds I have created from sources including percussive impact sounds, electronic toys and field recorded sounds. These have been mangled, glitched and processed in various ways in Sensomusic Usine Hollyhock II using Incipit by Inear Display; Subvert, Convex and Cryogen by Glitchmachines; Fog Convolver by Audio Thing and various delays and reverbs. The effects have been used in various configurations and routings.

The pack contains 296 samples comprising of atmospheres, textures, glitches, robotic artefacts and impacts which give the sound of a dystopian future.

I've added a demo track of some of the sounds which are played clean with no effects applied. The two demo songs have been created using only sounds from the sample pack processed with Tremolator by Soundtoys; Incipit by Inear Display; Cryogen by Glitchmachines; Spaces and Deelay by Hornet.

Show/Hide Rules

Any operating system, any plugin format, a stand-alone application, a sound library - anything that will assist in music making goes! You have two months to get it together - submissions will end on November 30th, 2016. They will all then be hosted for download on the KVR server and released "AT ONCE" for public appraisal and voting!

Although anything goes, you should consider how to appeal to the largest market - things such as open source or being multi-platform may garner a bigger audience, and consequently more votes. This is your call though. Whatever you are comfortable with!

The Basics:

  • Anyone may enter (However, the NAMM Show Grand Prize, see below, is only available to entrants aged 21 or older).
  • Your entry must be an original creation made by you (your team / crew / company / family). Of course you may reuse code / modules / development frameworks, but the actual plugin / application / sound library should be a new, original creation, not just an obviously cut-down subset of a program you have already written.
  • Your entry must not break any copyright rules or license agreements - if your entry uses GPL code then your code should adhere to any restrictions imposed by this, for example.
  • Your entry must not be restricted in any way that could make it appear to be a demo / trial version for a subsequent "full" release. i.e. It must not be save-disabled or beep every few seconds or nag the user to donate / pay, etc. Your entry should be fully functioning and remain fully functioning forever.
  • Your entry may support any operating system(s) in general use for making music: Windows, Mac OS X, Linux, iOS or Android.
  • Your entry may support any plugin format, or be a stand alone application / utility, or be a sound / sample library.
  • You may use any programming language or development environment (e.g. programming languages such as C++, Delphi, Java, etc. or any of the myriad development applications such as SynthEdit, Flowstone, Max, etc.).
  • Design and testing must be done in private - public beta testing is not allowed as this may affect the voting process.
  • During the voting period you may update your entry but updates must be bug fixes ONLY. You are NOT allowed to add new features or rework existing ones during the voting period.
  • You grant KVRaudio.com the permission to distribute your entry for download via our server from December 1st, 2016, onwards.
  • You grant KVRaudio.com the permission to act on your behalf, without monetary involvement, for your entry to be published and/or publicized in/on written publications with or without accompanied media such as CDs and DVDs, as well as online publications. You may choose to opt out via a written (email) disapproval of such permission at the time of your entry. KVRaudio.com will not seek or make attempts at financial gain by promoting your entries on written or online publications.

How To Enter:

  • To enter you will need a KVR Developer Account [get one here - it's free]. If you already manage your products and submit news directly at KVR, you will already have one.
  • Access the Developer Control area and add your entry as a new product but remember to also set the KVRDC16 flag. Anything flagged as KVRDC16 will NOT be made live on KVR until the KVRDC16 go live date of December, 2016.


  • KVR Members will vote for their favourite entries between December 1st-18th, 2016. Depending on the amount of submissions, the voting period (and consequently the winner announcement date) may be extended for another week or so. All KVR members will be eligible to vote although we may instigate some restrictions at the time of voting - maximum joined date, minimum number of posts, etc. - to help prevent voter fraud.
  • Voting will be in the form of selecting a top 5:
    • 1st choice will be awarded 5 points.
    • 2nd choice will be awarded 4 points.
    • 3rd choice will be awarded 3 points.
    • 4th choice will be awarded 2 points.
    • 5th choice will be awarded 1 point.
  • The winners will be announced on December 19th, 2016.
  • The prize fund will be delivered to the winners (or charity or recipient of the winners' choices) via PayPal within a week of the winner being announced.

The Grand Prize: Win a free trip to the 2017 NAMM Show in Anaheim, CA, USA

  • I agree to allow KVR Audio and NAMM to use my image for promotional purposes.
  • I also consent that I am submitting original material, of which I own all the rights.
  • I understand that event details are subject to change.
  • One winner will be selected from all entries for the Grand Prize, which includes airfare to and from Anaheim, CA for one person and one hotel room during the NAMM show, January 19-22, 2017.
  • The Grand Prize winner must be 21 or over in order to win the travel prize (this does not affect the KVR member donations part of KVRC16).
  • In the event that the winner is ineligible for the Grand Prize, or cannot attend the NAMM show, KVR Audio will select the winner with the next highest level of votes.
  • The Grand Prize is not transferrable.
  • The Grand Prize winner may reside anywhere in the world.
  • Entries will be voted on by the public during the voting period.
  • The highest number of votes determines the winner.
  • Void where prohibited by law.
  • Taxes and fees are the responsibility of the winner.

The Prize Fund (Money Money Money)

  • The prize will be cold, hard, cash, made up from donations from the KVR community. Donations can be made via PayPal and will be held in escrow by KVR Audio until the winner has been selected. The prize will be paid to the eventual winner via PayPal. We'll endeavor to keep the prize fund total updated here.
  • The prize fund will be split:
    • 30% to the Windows Plugin or Standalone Application entry with the most votes 1, 2
    • 30% to the Mac OS X Plugin or Standalone Application entry with the most votes 1, 2
    • 20% to the next highest placed entry
    • 10% to the highest placed Soundware entry
    • 10% to a wild card random selection (maybe an iOS or Android entry, if we get any!)
  • Additional prizes, donated by fellow developers, will also be available and distributed on an ad-hoc basis. If you wish to donate something please contact laura@kvraudio.com

1 These can be the same entry. If it is multi-format and gets the most votes the entrant would receive 60% of the prize fund.

2 Yes we know Linux (and other OS) appears to be overlooked but the Linux (and other OS) userbase at KVR is very small so we'll concentrate prize distribution on the two major Operating Systems for audio production - Windows and Mac OS X. However, in the event of the unlikely situation that the entry with the most votes is for Linux (or another OS) only it will be awarded 30% of the prize fund and the next 40% will be split between the highest placed Windows and Mac OS X entries (20% each) and the "next highest placed entry" will receive 10% instead of 20%.

Good Luck!
