Check the listing for details. Blue Lantern Mini Shimmery MK2 Cymbal Percussion Generator Eurorack Synth Module. Condition: New. Listed at 122.50 USD. Blue Lantern Mini Shimmery MK2 Cymbal Percussion Generator Eurorack Synth Module Description There are 3 square wave oscillators that ring mod each other twice to produce shimmery sounding tones or drones. The internal sound does not stop. When you patch from the drone jack it is a constant sound. You use the A, B, and C knobs to tune each individual oscillator. Then you use the Tune Knob to adjust all of the oscillators when you find that perfect sound. There is a TR influenced circuit that uses the abrupt dirty transistor vca to produce hi-hats or metallic percussion. I added the essential accent control to vary the amplitude. You need a gate or trigger signal from an lfo, etc, to activate the TR VCA portion of the module. Otherwise if you want clean hi-fi sounding percussion from this unit, you patch from the Drone jack to your hi quality ssm2164, or cool audio v2164 vca.
