The Collidoscope is a prototype synthesiser designed by researchers Ben Bengler & Fiore Martin.
Based on a granular synthesiszer engine the instrument can be played by two performers at the same time (as they stand opposite one another on the sides of the unit) using the 2 built-in sets of keyboard, gooseneck microphone, color display and controllers.
The Collidoscope samples from the microphones (or line inputs) and displays in real time a waveform of the sample and allows it to be played back instantly. The main sliding knob positioned below the waveform allows for the visual selection of a portion of the sample to be played by moving it horizontally, and for the modification of the size of the portion being looped by rotating the knob. There are also two backlit octave selection buttons and a sturdy metal button next to the microphone base to start sampling.
This is easily one of the largest steps toward closing the gap between the performer and the sampling process, something almost every audio engineer encounters.
