Korg Monotron – LFO Sync Mod Compilation
This is a compilation of the possibilities of a LFO-sync modded Korg Monotron analog synthesizer.
In this mod (see also http://stevewoodward.posterous.com/lfo-reset-point-on-korg-monotron), the low-frequency oscillator (LFO) of the Monotron (sync slave) can be retriggered by pulse signals in this case from a Roland TR-626 rhyrtm computer (sync master). The trigger signals sent by the TR-626 can be programmed by its rimshot pattern. Shuffled notes of the sync master are directly introduced into the Monotron LFO, to give also a shuffle effect.
Advantages of this mod is the low-budget (~2$, only a few cables and a 3.5 mm plug are needed) and the possibility to sync other music devices to the TR-626 via MIDI at the same time. Like shown here a Nanoloop (http://www.nanoloop.de/gameboy) cadtridge for Gameboy Classic, can also be synced with the same pulses.
This LFO-sync Mod enhances the possibilities of the Korg Monotron significantly.
It allows to use the synchronized Monotron analog filter LFO for external audio, as well as for the internal voltage controlled oscillator (VCO).
If the Monotron LFO frequency is tuned higher the retrigger frequency of the sync master, there is also the possiblilty of cross-modulation effects, like for the unsynced version.
