8bit House with Nanoloop + circuit-bent Monotron

October 26, 2012 · Posted in Uncategorized · Comment 

Both, a circuit-bent Korg Monotron and a Nanoloop (Synthesizer and Sequencer on Nintendo Gameboy) are synced by the trigger impulses sent by a Roland TR-626 drum computer.
This allows to filter the raw chiptune sound of Nanoloop by the analog filter of the Monotron. The retrigger of the Monotron LFO is the red wire. The sync mod (circuit-bending) is done like shown here: http://stevewoodward.posterous.com/lfo-reset-point-on-korg-monotron

Circuit Bent Coleco Talking Teacher

June 3, 2012 · Posted in Uncategorized · Comment 

Background info:

Here’s my take on bending the Coleco Talking Teacher toy. Four bends have been added: short glitch loop, long glitch loop, unsteady long glitch loop, and pitch adjustment. A side cart was added to make room for the controls.

This is one of the most stable talking toys I have bent. The long and short loops are repeatable, so the glitches can be played like you would a drum machine. The sound is also very clear.

Circuit Bending – Build Your Own Instrument

DIY and Circuit Bending all the way:

“Filmmmaker Maren Sextro created this portrait of me for Groove.de in May 2012. Together, we visited the flea market and my studio, and spoke about my approach to sound, performance, “circuit bending” (a term I rarely use to describe my own constructions), DIY electronics and self-education.”
