[sdiy] optical retrofit for minis?

[Gene Stopp]

Ooops - forgot to say that although the contacts on the Musonics mini were
unstuitable for the stock analog interface, the digital scanner pull-up
values and demux inputs provided a high enough impedance that the crappy
contacts work just fine.

This is a very interesting topic...

A while back I had no qualms about hacking into second-hand analogs that I
had acquired. I added 1/4" output jacks to my ARP 2600, next to the 1/8"
jacks. I added CV in/out jacks to ARP Odysseys. A friend had a Musonics
Minimoog (s/n in the 1200's, metal panel, full dial markings, all
transistor, which I now own after a trade) and the keyboard contacts were
awful. Cleaning didn't help. I added an Electronotes-style digital key
scanner with DAC, tucked under the keyboard, which works great.
