just tried it with the A-188-1 (2048) BBD and the A-110...increasing the delay time to "the crud zone" with lots of modulation from the square wave and a little PWM provided some interesting results...


thanks for the idea...

Subject: 1 Waveshaping with BBDs

Hi

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

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
