LM13600 VCO On the Board and working...

[Scott Gravenhorst, Synthaholic]

The first part of my VC-Noise Gen / Complex Waveform Gen is working 
well.  It provides 3 CMOS clock outputs at F, F/2 and F/4.  I 
discovered that there is a 'best linearity' zone to it's operation.  
This zone spans about 6 and a half octaves c-c and I have taylored the 
range components to keep it there.  It stays in tune very well across 
the entire keyboard (5 octaves c-c) within that range.  There is also a 
switch to bypass the high end limit to allow it to go above the range 
of human hearing.  In this range it is still useful, tho not musically, 
for clocking a noise generator.  In it's musically useful range, I am 
clocking a small FSR with very a simple feedback system.  Now that I 
have the musical range nailed down I will build up the Complex Waveform 
generator.  It should produce some interesting sounds.  Unfortunately, 
the weekend endeth and the soldering iron must be unplugged...
