zero delay feedback SVF in gen~

November 16, 2012 | 6:22 pm

I have been experimenting with some zero delay feedback filters, as used in the latest and greatest virtual analogue synths. I’m a long way from understanding it myself, but i’ve had fun playing with some code that others have published. Attached is an SVF. The cutoff freq can be much higher than the standard svf cutoff freq.

Two more… a transistor ladder (moog-like) and a diode ladder (VCS3/TB303 like)
