Videos Chromosome 17 (ring delay fx) Posted on June 20, 2018June 20, 2018 by Charlie 20 Jun Here is my first design using the PT2399 delay chip. The feedback loop goes via a ring mod. The other source for the ring mod is derived either from the input signal or an injected signal. The Clock Output socket is divided down to the quarter beat.
