Re: A-147 VC-LFO

Hi Erik,

The short answer is 'no'. However there is an exponential converter 
in the circuit, so it does have an exponential 'feel' to it, but 
there is no means to trim it at all, and from measurements from my 
unit, it seems to be very roughly about 0.5V/octave (or 2 octaves per 
volt of input):

CV in (V)  Freq (Hz)
1          0.08
2          0.4
3          2.2 
4          10.4
5          47

(Very rough and ready measurements, feeding a voltage into CV, 
with 'freq' at 0, CV gain at max.)
