Guys I have problem with osc mod envelop. When I choose osc pitch and set amount on -0,2 or 0,2 I have big drift pith this osc to other osc without mod env. Maybe it's bug. Please check on your NW 2.

I just tried this on an Init patch - I'm not seeing any unexpected behaviour. I enabled two layers, dialled one with 0.2 osc mod pitch amount (and I also tried other amounts), and the other with none. I get a little expected pitch movement on the modulated layer, as per the envelope settings, and then it settles back to being perfectly in tune with the 0.0 layer.

But... the Osc Mod Env has the AR (Attack/Release) mode as well, and that works a different way. For the default AD (Attack/Decay) mode, modulated pitch deviates from 0 (in tune) during the attack phase, and goes back to it in the decay phase. Notes start and finish bang in tune, as long as the osc mod envelope has enough time to complete its whole cycle. However, if you have it in AR mode then the attack phase brings the note into tune - where it sits for the sustain portion (it really should be called an 'ASR') - and then pulls it back out again when the key is released and the envelope release phase triggers. So notes essentially begin and end out of tune. I wonder if it's that you're hearing. It certainly can make for some super-wonky tuning if you have amp release time set quite long. It would obviously do it with any envelope amount though, not just 0.2.

This is on the latest 1.14 OS, btw.

thanks. When I set -0.2 or 0.2 I have drift 1 semitone
I add mp3.

That is normal, as far as I can make out. Pretty much how mine sounds, in AD mode, 0.2 amount, instant attack and a second or so decay. With an amount or 2.7 it's already an octave. Were you looking for much finer control (ie. being able to modulate by just a few cents)?

yeap, nord wave 1 or nord lead 2x doesn't have drift like a nord wave 2. On NW2 I can't get small pitch modulation.
