They created two pyramid-shaped analogue synthesizers with hand painted casings. The design began as part of an animated music video that Pete made for The Horrors, and then afterwards Richard Russell (XL Recordings) decided to commission a real life version. It was decided to make two synths in the end, one for Richard and one for The Horrors to use.
Each synth contains a Music From Outer Space Sound Lab mark II. This provides each synth with two stable VCOs, a state variable VCF, two envelope generators, VCA, LFO, patchable sample and hold, white noise generator and an audio mixer.
There are plenty of switches and sockets for creative signal routing, and external inputs to process your microphone, guitar or electric ocarina. Control voltage inputs allow other synths and sequencers to control different parameters. Each pyramid also has a MFOS 8-stage phaser, built in speakers and 72 colour changing LEDs.
