8bit House with Nanoloop + circuit-bent Monotron
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
