Hi York.

The trimming problem seems to be getting solved. I am finding a little difficult to tune exactly since there are few trimming potentiometer to be adjusted. But seems I am getting closer to a conventional tonal scale as I compare to the piano sound from my digital worstation.

I tested the LFO sending a square wave to the A140 and noticed that it responded. The A190-2 seems that is maybe faulty because it's not sending the gate to any module. Maybe it's my fault.
