THE PLAN
Use an arduino and stripboard components to read LFO signals from the FSS Brunswick mono-synth kit and use that data to control Neopixel LEDs. Also within the same system incorporate an arduino powered ‘sonar theremin’ to receive physical motion/performance data and output that as MIDI data for use with Touchdesigner and Ableton. This will create an interactive AV experience and improve the functionality / compatibility of the synth.
INSPIRATION
Using ultrasonic waves to control sound is a pretty old idea, beginning with the Theremin. This is still made today in many forms and its sound/look is iconic.
The modern interpretation is Roland’s D-beam system used in some of their keyboards, it is widely regarded as impractical to use while playing keys and has become a bit of a meme in the synth world. Newer Roland synths do not feature it. However in a key-less synth senario it could be a powerful performance tool.
The MI.MU gloves first publicised by musician Imogen Heap were another point of inspiration. This was my first exposure to gesture based sound control in around 2014. The idea has stuck with me, while heap uses the gloves purely for sound control while singing, the idea of using one’s hands to control elements of a performance (beyond just pressing keys, turning knobs ect.) has always been of interest to me.
