Pitchloop89

by Robert Henke (Monolake)

PitchLoop89 is a new pitch-shifting device inspired by the Publison DHM 89, created in collaboration with Robert Henke. Experiment with jittery glitch effects, delayed digital shimmers and outlandish vibrato in the studio or onstage.

Experiment with the vintage digital charm of a classic piece of hardware without having to track down and invest in the original. The DHM 89 pitch-shifting delay unit was released in 1979 by the French manufacturer Publison. 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.

Jumps, jolts and jitters

The device contains two independent pitch-shifting delays. These circular delays hold short snippets of audio, the length of which changes according to the bandwidth selected. 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. Changing the speed and direction of playback in the delays allow for pitch shifting and segment reversal. 

The two pitch-shifting devices can function independently, or as a single stereo effect, and new filtering and feedback routing enhancements allow control over sound that wasn’t possible with the DHM 89. Shape the sound of each channel with low pass and high pass filters, and play around with the routing options – L/R keeps the channels independent, Sum combines both signals, and Cross sends each signal into the opposite pitch shifter channel. Experimenting with different routing options in combination with different pitch shift settings can create fascinating outcomes such as rising and falling pitch patterns and complex cascades of feedback.

Other notable functions include a hold button, a vibrato LFO, and a position modulation LFO. The hold button lets you freeze and loop the audio of one or both of the channels. Playing around with freezing and unfreezing different audio signals can create shuddering glitches, jolting rhythms and fractured textures. The vibrato LFO can be set to either sine or square wave for smooth or robotic pulsation, and the position modulation LFO has seven waveform options including move – a smooth random movement. Modulating the position with either the LFO or the random button can create effects ranging from spacious pseudo-reverbs to strange rhythmical warping. 

Tactile sound design

PitchLoop89 was designed to be playful and tactile, and the real fun starts when it’s used with Push or a MIDI controller. It has deep Push integration, with all parameters set up to be controlled via six menu banks. It’s easy to get lost tweaking parameters to create textures out of samples or transforming organic sounds into fields of digital pointillism. Recording this output in the studio gives you endless variation to work with. Onstage, it’s an exciting and versatile effect to wield in order to deconstruct rhythmic material on the fly, conjure synthetic dronescapes or just add a pinch of digital character to your sounds.
