In the original hardware this was due to a RAM limitation, but it’s now a creative feature, as switching between sample rates creates octave jumps, and low sample rates can change the character of the sound and create interesting sonic artifacts. These circular delays hold short snippets of audio, the length of which changes according to the bandwidth selected.

The device contains two independent pitch-shifting delays. PitchLoop89 takes its cues from the hardware, preserving some original limitations for creative reasons, while making some contemporary enhancements for sound control, versatility and performability. The DHM 89 pitch-shifting delay unit was released in 1979 by the French manufacturer Publison.

Experiment with the vintage digital charm of a classic piece of hardware without having to track down and invest in the original.
