I have just finished my 4Pole Mission everything seems fine with only two points.
1. It doesn’t appear to save the 4pm setting - minor inconvenience
2. I am getting modulation break through on G# on every octave. All the other keys in the octaves are normal.
Tried two different keyboards and get the same problem. If you change the tuning of the 4pm then the note that gets the breakthough changes in relation.
Also if you hold G# and then use the pitch wheel to bend the note the breakthrough goes away
It is not apparent on all patches and the effect is not the same as applying the mod wheel
patches #3 Moonrise is the most obious example
It sounds either like lfo or slight xmod or on some patches like env/pre glide on the affected note.
Also when calibrating the self oscillation of the VCF C-C the pitch it actually plays is G# - is this just a conincidence ?
I have attached an MP3 that I hope illustrates the problem.
My electronics knowledge is a little rusty so please forgive me if I have done or missed something obviously wrong
