Sv: Re: [sdiy] OT: Akai MPC4000 encoder

[Daniel Araya]

Thanks!
It seems like it is an optical encoder with electronics on board. I'll try to get hold of a new one and if that fails i'm going to try to replace it with a mechanical ALPS encoder.

Been a while since I've dealt with Copal.  They only list a few encoders on
their page but maybe its a start.
