[sdiy] MS-20 tempco (was Model D service)

[Tony Kalomiris]

They are both exponential Fm, but perhaps due to the unusual Hz/V it sounds more pleasing to my ears. 
As I mentioned with an external CV (Midi to CV) it was awesome to be able to "play" the keyboard along with the sequence, or transpose the piece. 
All Midi to CV's forced you to use linear input IIRC, at least the earlier ones, defeating the keyboard. Unless you had an MS-02. or modded it for 1v/oct.
Agree, it was my favourite scheme.
