[sdiy] Juno 6/60 SH rate for filter cv

[Kyle Stephens]

Well, the max arpeg rate is 50Hz, so Mr. Nyquist sez at least 100Hz?

CPU clock has a 1Mhz xtal?

Fumble fumble...

I'll run my Sherman LFO into the Juno's VCF in when I get back from work tonight. The literature says it goes from 1Hz - 3.6kHz. I can beat the LFO out against some notes to guestimate at what point, if any, you start getting some aliasing.
