MTurboFilter preset making action

[jmg8]

Hey everyone
At Melda we have been working hard to make MTurboFilter feature complete by adding many creative modules and features. The time has come to start the design work to make filter presets. We invite you to join in on the action.

WHAT IS MTURBOFILTER?
MTF is a plugin and a module inside MSoundFactory.
It will contain presets that cover a wide range of filter types.
The plugin version features built-in modulation while the MSF module uses our per-voice modulation system.

THE GOAL.
We want to make a collection of filter algorithms of all different types. Standard, analog modelled, creative, distorting, vowel, multi-mode, morphing, resonating, LoFi, everything really. The most important thing is that they sound great!

WHAT IS IN IT FOR YOU?
That depends on how many filters you design and how good they are. For the most part, your contribution will bag you a free license for this amazing plugin. But if you are really great, and/or provide lots of presets, then we can discuss other options.

HOW TO MAKE THE PRESETS.
Similar to the algorithms in MTurboReverb, the filters for MTF will be created using the syntax editor. Please read through the help info there to get an understanding of what this thing is capable of (a LOT!). You will also find a few preset examples, showing a few things that are possible.
You can get very creative here as there are almost unlimited possibilities.
The filter algorithms are built using a combination of various filters and routings, and there are also some creative processors there such as distortion and dynamics. The 4 main controls, FREQUENCY, Q, CHARACTER and DRIVE should always be attached to at least one parameter so that they change the sound in some way. FREQUENCY and Q should mostly be controlling the expected frequency and resonance. DRIVE is attached by default to the dry/wet of distortions but can be overridden and mapped to other things if you wish. CHARACTER is completely free to use for creative things.

HOW TO SHARE THE PRESETS.
When it is time to show us your creations, please export them all as a single file using the export option in the preset browser. You can send them to me at jason@meldaproduction.com

This sounds fun, when is the deadline for submissions, and are we allowed to put artist attribution in the Preset Information sections?

[jmg8]

Hey, the deadline will be the end of March. Also, it is OK to put your artist attribution in the preset information.

PLEASE --> use only great Algos... quality before quantity. Please find some people who really know what they´re doing.

I thought Melda and Imageline will do things like this from now. ,,,,

How many otherwise knowledgeable folks here have a clue as to what goes into designing a filter? I have enthusiastically dived into preset making action here in the past, but I'm totally at sea on this one. I wouldn't even know where to go to research this other than the deeply complex web sources on DSP techniques for which I've long ago forgotten the math needed to comprehend these things. Sadly, I'll be passing on this initiative. But I do wonder how many of the regular contributors will know what they're doing on this one. Finding people who know what they're doing may not be easily done. Just my 2 cents.

Exactly. Therfore a strict quality control will be extremely important on this one. --> without any hestiation to exclude some architectures so only top notch Filters get into the final version. (no pun intended)

I would even suggest to look for professional contributers with a history/knowledge/training on desiging Filter algorithms.

Personally, I'm looking forward to the tutorials. The one for MTurboReverb are amazing and I learned a lot about reverb design.

You couldn´t undelined my point more than this.

(don´t get me wrong, I also learned a bunch while designing Reverbs for MTR and I also look forward to the insights the tutorials will deliver to me/us)

But for this I would like to get some ground-breaking (or at least state of the art) Filters --> and not some results of tinkering in the "unknown".

Even Vojtech seems to keep a healthy distance to "analog filter" design because it is very hard and a lot of very complex math seems to be involved.

[smadger]

Perhaps I'm reading this wrong, and apologies if so, but it feels like there's a lot of negativity and gatekeeping going on in this thread. If Melda are asking for contributions, and people want to send something they should be encouraged to take that opportunity. It's up to Melda if they get selected and people may learn about filters in the process. We should all be encouraging everybody to get involved.

And remember, you don't have to "design" a filter if you don't want to, you don't need to know DSP, the nuts and bolts have already been made, bandpass, lowpass, etc and even saturation modules are already there for you. Sure the language is probably open enough to allow you to if you want, but all you need to do is create great presets using those building blocks if not.

Again, apologies if I'm reading these messages in the wrong way, reading text is hard sometimes

That would be great. But it seems people in the audio industry are rather secretive and all algorithms in MTurboFilter are public. We'll see.

No don´t be sorry. You are talking about a extremely valuable point. I also ask myself what is the goal/intent of this "Filter design action".

1.) If Melda is only looking for Filter-arrangemnts of already excisitng modules then I am fine with amateur contributions. (But ain´t we got something like that in the regular Filter-module already where Vojtech created (beside the regualr Filter types) some random Filter arrangements e.g. Polymorph.

2.) But I had something more in mind like --> really doing complex math to create e.g. authentic emulations like TB-303 or Moog Ladder Filters. In this case I would rather like to see very knowledegeable coders/mathematician to create those algorithms.

Unless they get payed for their knowledge.

But even some like u-he or cytomic are very open to share their knowledge for free --> or where do you think we got the "fast Filter module" from --> it is a variation of a freely shared cytomic filter design (if i remeber correctly). Also the codebase of Vital and Surge are open-source so a knowlegeable person could interpret those filters for MTF. --> But first you need to understand the underlying math.

[Held]

Sure, but it's one thing to have your knowledge used to build a product and another to make your knowledge available for anyone who downloads the MTurboFilter demo.

Anyway, in the spirit of sharing knowledge, here's my attempt at recreating the Mini Moog 4-Pole filter based on the knowledge shared here: https://www.earlevel.com/main/2016/02/2 ... he-4-pole/

It sounds pretty good, I think. At least compared to the Mini V which is my only reference. Q controls the amount of feedback and Drive the delay time.

Code: Select all

FB(q; 0.001*d)[4S[LP6(f)]]

Edit: Try modulating the Drive control

I would love to see myself proofen wrong.

I am going to try this Filter out next time i am in the studio.

Maybe my concerns aren´t justified at all.
