Re: Paia 2720 rebuild advise
Scott, thanks for responding and advising. Though the 2700 system is pretty straight forward expertise is a welcome commodity.
Updates include: VCA issues resolved.
Power modules corrected. EG running. (Considering using a Doepfer ADSR to "modernize" waveshaping.)
Parts for putting tuning trimpots on a faceplate now in house. Cutting acrylic faceplate today. (Boring holes tomorrow).
Trying to use a midivox arduino shield as a CV converter. I realized the VCO is not exponential. So as I am not prepared to build a keyboard from scratch please give details on the converter mentioned in other threads. I have found via web searches a Japanese version I believe was used in Korgs, around the same time, which look easy enough to perf board, but still lurking Arduino forums for programing suggestions.
Posting pictures this later week.
