Eml synthesizers

So, i knew something was confusing and i looked into my old emails...

dave wilson of NESM had explained it to me before and i just remembered it 
backwards:


"The Museum is doing well. The VCOs on the 200 are Hz/Volt, not Oct/Volt, so  
they can be made to
track your Korg MS-20 or your Yamaha CS-40M, but not an ARP or Moog  
synthesizer. The EML 101
has an output called "CM2" (Control Mode 2) that is a Hz/Volt output that  can 
drive the 200's VCOs.
Older EML 101s have a CM3, same thing but high note priority for duophonic;  
More recent 101s have
a Sequencer input jack instead."

The 200 is basically just a bare integrator IC with a UJT,  cap and diode 
network in the feedback loop. The center frequency and both  swings are all 
summed together after their input resistors into the ame op amp  input as the 
feedback network. The diode and UJT act as choppers to produce the  sawtooth 
output from the integrator.
 
The output of the op amp goes to the 470 ohm output impedance  resistor and 
capacitively coupled to the two outputs, which are hardwired to  each other.
 
There's no current control, differentiation or exponential  amplifier. So, it 
doesn't look like it was designed with any sort of scaling  capacity in mind.
