Hi.

A little delicate question. How combinator exactly works?

I noticed, that when I send in some short burst and turn dampening really high, it gets out of tune by 15 to 30 cents.

I was planing patch with dampening used as expression tool, but this frequency shift is hard to compensate manually.

Any idea what could have caused it?

It's a comb filter

Have you checked Howie's new manual? It it explains it rather well...

thx

I know about the manual, but yeah, I kind of overlooked the comb chapter. Amazingly explained here, thx again.

But still doesn't solve the problem.

Here's another screen:

Just comb with internnal impulse generator. Drift off. Still 18 cents. Lower I go detune increases. This is painfull most in simulating bass guitar, wehere it goes up to 35 cents. :-/

It's not a problem. It's what happens when you dampen guitar strings as well.
You could make things more to your liking if you place the modwheel modulation next to the tone or flavour settings, then adjust as needed to bring the pitch to where you want when using the modwheel. As tone and flavour have an influence on pitch as well, depending on which comb mode your using.
Try them both to hear which one, then set the modwheel to that tone or flavour setting, and adjust.
Also make sure you don't have any "midi learn" enabled on one of the parameters in there. Right click a knob and select midi unlearn, just to be sure.
btw...I can't see your pics as they're on dropbox, which I'm blocked from.

Well according to Howard's manual, in the simple comb mode Tone and Flavour settings have no effect. :-/

My standard approach to the comb module is to throw it in, tweak some knobs and hope for the best, lol. I've got some cool effects that way... It's certainly one of the most intimidating modules in Zebra.

I don't know about that.
You don't need a manual to tell you what your ears can clearly hear.
Turn the Tone and Flavour knobs about, and hear it's effect for yourself.
It will clearly change the overall pitch. It does depend on which comb mode your in though.

The damp factor affects the pitch. I've already compensated for that quite a bit, but it's really difficult to keep the pitch steady. As this also happens in real world instruments (think strings...), I think it isn't even all too desirable to work around that problem alltogether.

Thus, one indeed needs to listen if Damp is set all the way up, and if perfect pitch is desired. In which case e.g. key scaling or tune modulation per ModMapper could be the weapon of choice.

Ok, cool. I just wanted to know if there isn't any workaround. Thank you very much.
