Powertran DDL - pitch/trig mod part2

Powertran Digital Delay Line with pitch/trig mod board. This is a quick video of the pitch being controlled by a prototype cellular automata oscillator module with an OLED display. DDL is in freeze mode so works a bit like an 8 bit sampler. No trigger connected in this video. Audio input is sampled directly from Mudley Talker Junior.
