Some Zebra modulation questions

[trance_lucent]

1. On the Osc GUI there is "Wave" knob changing in the range 1...16, and its mod knob ("WarpModDepth") changing in the range "0...16". Why? If Wave = 1, and I modulate it with WarpModDepth, I have to limit modulation by 15 (1 + 15 = 16), otherwise if I am maxing modulation with value = 16, the actual Wave value = 1 + 16 = 17.

2. Is there ways to hold modulation values? (No, as far as I know, so it is request). For example, I want to automate some parameter from host or from Zebra GLFO and use it's value on the moment when Note=on event fires. Some sort of ModHold module would be handy. At the current moment I can to use ModMapper with Alternate method, but it changes its value according to every note on, so polyphonic chords change values by several steps.

Yes, the maximum usable modulation range is 15 although you can set 16. An oversight, but seeing as it's been like that since day one I think it's a bit too late to change now.

Not sure I fully understand, as you mentioned "automation" (in which case you could simply use horizontal lines in your automation track). However, I can imagine wanting *realtime control* e.g. the output from your mod wheel gets sampled and held until the next note after all notes are released. Hmmm... I don't think that's possible in Z2, but it might be a good idea for Z3!

Yes, Howard, I meant the feature like this. And it could "sample and hold" not only mod wheel and other controls, but also internal Zebra modulation, like GLFOs and MSEGs.

Also there is some other thoughs about Zebra modulation and ModProcessors. For example, it would be cool to have several "random" mod sources (to keep LFOs for greater things than just RNG, I wrote about it), or sometimes I want to "quantize" LFO - i. e. to make octaves or semitones jumps in pitch. Also ModMixer could have some more math. But I am coming to "unreasonable demands thread" again.

+1 on the sample/hold and random modulation source option...

You can use a modmapper to make a 'quantized' lfo

Also there is another task I need right now in the current project. I want to change wavetable with random hold GLFO, but with noticeable "slides" between holded values. Tryed to set "Slew" to "slow", but it isn't enough slow for me. So there have to be adjustable "slew" knob or (even better) ModFilter - some sort of low pass filter for modulation. Or there are some solutions in Z2 currently? If not, I may be have to try to assemble random->S&H LFO in Logic Environment, but this isn't easy task.

pdxindy: oh yes, I can use modmapper, but it isn't very handy to calculate and set right values for e.g. semitones. But in the new Z3 editor, I hope, there will be possible to set values from keyboard.[/b]

Well, I found the similarly sounding solution: random glide GLFO1 with rate controlled by GLFO2 (user curve looking like relatively narrow pulse) in the range 0...46. Slides can have some overshooting though.

This is what the MSEG for. You can draw exactly where you want slower transition on what level.

Indeed it is not handy... but at least one can do it...

+1 for the lag generator!
