Been playing around with the Modular V a lot, one question though, I'm not sure if it's a bug or if I'm doing something incorrectly, but it appears that the pulsewidth modulation knob doesn't seem to affect square waveform oscillators 2 or 3, what could be the reason for that?
Driver 1 affect OSC 1-3.
Driver 2 affect OSC 4-6.
Driver 3 Affect OSC 7-9.
All works for me. The second and third OSC in every driver section is affected like the first OSC in each driver section.
I can't tell you a coarse, why it should'nt work for you, unless you can't hear or don't use the oscilators somehow. So be sure the oscilators has an active impact on the sound somehow.
As i can't see your settings i can't tell if you are doing something incorrect. More info - especially a screenshot if possible could be nice.
I can only suggest you try things out as simple as possible first to be sure. Check one OSC and one Waveform at a time.
Lets hear how that turns out.
