Waveshaping with BBDs

2008-03-03 by Florian Anwander

Hi

In the synth-diy list someone popped up with the idea to use a delay as 
Waveshaper/Phasemodulator.

The basic idea is very simple. Use a triangle send it to the BBD, and 
modulate with a rectangle from the same VCO:


    |-Triangle--->|Audio   |
VCO|             |  BBD   |-->Audioout
    |-Rectangle-->|CV in   |

Lets assume the rectangle starts with high when the triangle has its 
raising ramp.

   /\  /
  /  \/
  _   _
| | |
| |_|

This will cause the upward ramp to be faster and the down ramp be slower 
  (in principle).

Could someone try this?

Florian
