Casper Electronics is the live performance extension of Peter Edwards, who also designs synths for Bastl Instruments. Bastl have now officially adopted Peter’s ideas and let him run riot with a new range of Casper Electronics Eurorack modules under the Bastl banner. I think I’ve got that right. Anyway, at Superbooth he was showing the Dark Matter feedback module under a mass of cables.
It’s a feedback module. It uses an analogue mixer to generate overtones and distortion. It has a VCA, EQ and a feedback loop. Mix in your signal, turn up the feedback and you have an “intense, thick and brutal sound”. Everything is voltage controlled. It has an envelope follower which you can use to fade in the feedback effect. The depth of feedback is governed by a crossfader along the bottom of the module. In some ways it’s the idea of pushing circuits to breaking point but in a controlled and pleasing manner. Sounds nuts! Check out the video below.
There were a couple of other prototypes in the rack – Party Mix and The Domain Shifter.
Party Mix is an analogue mixer giving you control over volume, panning and it has a send for effects. It has 4 channels of VCA designed to add colour and flavour to the sound. There are different slew modes to process incoming gates controlling the volume.
The Domain Shifter is an analogue to digital converter. Incoming signals are converted to binary values in various ways and promise to generate interesting rhythmic figures. It can also take audio and turn it into something digitally interesting. Not sure I understand all that!
