Will do!

Thanks for the post on the modes too, the modes were hard for me to wrap my head around with Ubermod. Your post does a good job answering a lot of my unasked questions on the different modes.

Well, I'm ONLY GETTING STARTED with the ValhallaÜberMod documentation!

Seriously. I'm only getting started. This is actually kind of a depressing concept for me. The writing isn't exactly "flowing" at this point in time.

I just posted a new blog entry, describing the MOD parameters in ValhallaÜberMod:

http://valhalladsp.wordpress.com/2012/0 ... arameters/

If anyone has any aspects of ÜberMod they want addressed sooner than others, just let me know. My current plan is to cover the rest of the controls, then get into tips and tricks. I need to put a "What is ÜberMod" post in there at some point, to give a high level overview that is easy enough to understand.

Another post, on how ValhallaÜberMod got its name:

http://valhalladsp.wordpress.com/2012/0 ... -the-name/

Someone asked me if I was into the Dead Kennedys. The answer is yes, but that isn't where the name came from. The guitarist from that band makes good use of the Echoplex, but I hadn't thought of that either while coding ÜberMod. Wow, this isn't a very interesting paragraph, now that I look at it.

A few new ÜberPresets, based around the DIFF section in ÜberMod. Both presets sound best with the mix set to 100% wet.

The first preset generates a diffuse chorus, using the internal modulation of the DIFF section, with some additional widening from the 2TapChorus slow modulation. This is similar to a stereo version of the DiffChorus blocks in the Eventide rack processors, but with some antiphase triangle modulation making things sound bigger.

Code: Select all

<ValhallaUberMod pluginVersion="1.0.0" presetName="DiffChorus" Mix="1" Depth="0.5" StereoWidth="0.5" Delay="0" Feedback="0" Spread="0.5" Slope="0.5" Skew="0.5" Random="0" TapGain="0.5" Diffusion="1" DiffSize="0.0204081628" DiffModRate="0.0890890881" DiffModDepth="0.30399999" LowCut="0" HighCut="1" SpatialXover="0.145728648" DetuneRate="0.0490490496" DetuneDepth="0.5" VibratoRate="0.298245579" VibratoDepth="0" OverMod="0" DriveInGain="0.375" DriveOutGain="0.75" DriveNoiseGain="0.333333343" FeedbackRotate="0.5" SmoothingTime="0.0990990996" ColorMode="0" DelaySync="0" type="0" DiffEnable="1" Drive="0" DrivePrePost="1" Speed="0"/>

The second preset just randomly moves the sound around your head in a really disturbing way. For some reason, moving sounds around your head in a really disturbing way seems to be one of my digital signal processing strengths (see: FreqEcho).

Code: Select all

<ValhallaUberMod pluginVersion="1.0.0" presetName="MovingInStereo" Mix="1" Depth="0" StereoWidth="0.5" Delay="0" Feedback="0" Spread="0.5" Slope="0.5" Skew="0.5" Random="0" TapGain="0.5" Diffusion="0.495999992" DiffSize="0" DiffModRate="0.0290290285" DiffModDepth="0.519999981" LowCut="0" HighCut="1" SpatialXover="0.145728648" DetuneRate="0.0490490496" DetuneDepth="0.5" VibratoRate="0.298245579" VibratoDepth="0" OverMod="0" DriveInGain="0.375" DriveOutGain="0.75" DriveNoiseGain="0.333333343" FeedbackRotate="0.5" SmoothingTime="0.0990990996" ColorMode="0" DelaySync="0" type="0" DiffEnable="1" Drive="0" DrivePrePost="1" Speed="0"/>

Got any sounds ya want to hear? Send yr suggestions my way! I like ÜberChallenges.

Controllable Through Zero Flanging? Like maybe we could park the sweep and then manually move the sweep around and over the zero point. Like on my Foxrox TZF.

As if Valhalla needed an endorsement, I saw this from Guy Sigsworth (http://en.wikipedia.org/wiki/Guy_Sigsworth) this morning:

So there you have it.

Heh heh heh...you got the mad scientist in me working on a solution.

I conducted a quick experiment with the 2TapChorus mode, with the following settings:

- WIDTH at 0% (summing left and right delays together)
- DELAY at 20 msec or so
- TAPS Spread at 100%
- TAPS Skew varied between -100% and 100%

The TAPS Skew controls the delay differences between left and right delays. At 0%, the delays are the same length. Either size of 0%, and the delays are unequal. So moving past 0% results in through zero flanging. I summed the inputs to mono before running ÜberMod, for maximum cancellations/reinforcements (I'm working on having this as a control for the next update).

One interesting thing I figured out with this experiment, is that the "through-zero" part of the flanging isn't all that important. Going all the way up to zero, and back down in the opposite direction, sounds identical to actually going through zero. It is being able to go all the way to zero proper that makes for the dramatic sound.

So, once I figured that out, I created a manually swept flanger preset that goes all the way to zero and back down, in a super dramatic way. It is TO-zero flanging.

Code: Select all

<ValhallaUberMod pluginVersion="1.0.1b2" presetName="Manual8TapFlanger" Mix="1" Depth="0" StereoWidth="0.5" Delay="0.0269000009" Feedback="0" Spread="0.263999999" Slope="0.5" Skew="1" Random="0" TapGain="0.5" Diffusion="0.5" DiffSize="0.0204081628" DiffModRate="0.0490490496" DiffModDepth="0.5" LowCut="0" HighCut="1" SpatialXover="0.145728648" DetuneRate="0.0490490496" DetuneDepth="0.5" VibratoRate="0.298245579" VibratoDepth="0" OverMod="0" DriveInGain="0.375" DriveOutGain="0.75" DriveNoiseGain="0.333333343" FeedbackRotate="0.5" SmoothingTime="0.211911917" ColorMode="0" DelaySync="0" type="0.25" DiffEnable="0" Drive="0" DrivePrePost="1" Speed="0"/>

To control this one, I'd recommend manually sweeping the TAPS Spread parameter. You could also sweep the DELAY parameter, but the TAPS Spread parameter will give you finer control, & will work great with automation and MIDI Controllers.

What is going on in this preset:

- The 8Taps mode is used, which provides 8 delay taps (4 left, 4 right).
- The DELAY is set to provide the maximum sweep range desired. This controls how low the flanger will sweep.
- TAPS Skew is set to 100%, to create the maximum difference between left and right taps. This wont affect the "to zero" flanging, but will create a nice stereo spread.
- Over in the WARP section, the Smoothing parameter is set for a few hundred milliseconds, to smooth out parameter changes. You can adjust this to taste.
- The money parameter: The TAPS Spread parameter controls the overall spread between the delay taps. At 100%, the taps are spread equidistant from each other. At 0%, they are right on top of each other, creating maximum reinforcement of the frequencies (this is the zero in the to-zero flanging). In between, different comb filtering effects happen. By adjusting the TAPS Spread parameter, you can control the comb filter frequency, and thus the flanging sound.

Not intense enough for you? Switch to the 16Tap or 32Tap mode. These will give you 2X or 4X the swept taps, respectively. The sound is reminiscent of BBD flangers with high amounts resonance, but those boxes couldn't achieve true "to zero" flanging - there was always a minimum delay that was non-zero.

Here is an experiment with 4 Synth tracks each one using it's own ÜberMod with individual synced-taps-settings:

I figured out a better name: TrueZero™ Flanging.

In order to claim that ÜberMod has TrueZero™ Flanging, I would need to come up with at least 1 mode that modulates the taps in this manner, instead of having to do so manually. I'm not planning on such a mode for the next ÜberUpdate (which is mainly bug fixes, although I have a new control in the development phase for allowing for some cool ping pong effects), but I'll be thinking about how to do this in the future.

My pleasure Sean, since I uploaded my first ÜberMod Demo on Decembre 15 my ÜberMod demos got +12.500 listeners which shows the positive hype around your new Baby.
