[sdiy] Three questions for you Synth Experts

[Chris Manders]

Hi folks
   
  I am building up my synth (and my knowledge) gradually.
  My synth will not be a modular, but I would like as many possible routings as I can get in a spall space. This synth will have two VCOs and one Noise generator.
   
  1) On the Synth's control panel between the two VCO sections I intend to have a SYNC switch (like the ARP Odyssey) for some cool Electric Guitar type sounds.
  I would like to experiment with FM sounds too, and I thought also about putting a control at this point on the panel which would feed a proportion of the VCO2 waveform output into the VCO1 FM input. Does this sound OK? Do I need any other controls to get this effect or give more options? (LFO and ADSR circuits aside, or course - I am just thinking of creating Clangorous Bell type sounds.)
   
  2) On the Mixer section on the control panel, I will have VCO1 level, VCO2 level and Noise level as is usual on a synth.
  I wanted to experiment with Ring Modulation, and thought about putting a control at this point on the panel to add a proportion of the result of the Ringmod circuit into the Mix. Does this sound OK? Do I need anything else or any other controls for basic Ringmod?
   
  3) There is a gap in my knowledge about CV inputs, and FM inputs. My VCOs that I have built have a CV input and also an FM input. I wonder if anyone could tell me the difference between the two inputs and why you would feed (say) an LFO signal into one and not the other. Anything to watch out for?
   
  Thanks for your assistance.
  Chris
