[sdiy] Korg MS20 Pitch to Voltage

[harrybissell at wowway.com]

Hi George

The MS-20 is a tachometer circuit, trade between too high ripple and too-slow
response. Only if you want some funny sounds should you consider it. 

The X-911 is more of what you need... it can give an ouput typically every
other cycle of input frequency.  That might still mean a latency of many
milliseconds.

What are yor trying to track ???
