Hello, I've been trying to find out about Speed Pmw, now, in the output of operational ic 13, I see the change in line with the oscilloscope. Also at the base of Q2, D1 .. It seems that up here is good, do not you think?
About the other problem, which does not work ADSR, is a problem in the EG switch, there are some presets that work with release, but other preset have no adsr, that does not work well for commutation, I looked, and belongs to do2 I've looked and I see a sign with my oscilloscope, and continuity with other ics ...
