LPG (VOLTAGE CONTROLLED LOPASS GATE)
The LPG is a distinctive module that incorporates both a low pass filter and VCA. The lopass gate is unique in the way that it simulates the characteristics of natural instruments. When used in LPG mode, additional harmonic content is added to louder sounds while quieter sounds pass through unmodified. This behavior imparts a rich, organic quality on the sounds.
LPG CONTROLS:
Frequency Modulation (MOD CV) - Attenuated MOD CV input controls the amount of lopass gate frequency modulation.
Mod / Ping Switch - Determines how the lopass gate responds to frequency modulation. In MOD mode, the MOD CV is used to sweep the frequency range of the lopass gate. In PING mode, the MOD CV is converted to a short trigger used to ping or strike the lopass gate. The PING mode takes advantage of the lopass gates fast attack and slow decay to create organic percussive sounds with a natural decay. The MOD CV input is internally patched to the envelope generator output. This routing can be bypassed by patching into the LPG CV IN input jack.
Frequency Control - In filter mode, the frequency knob controls the center frequency of the filter. In VCA mode, the frequency knob controls the pass through signal level. In lopass gate mode, the frequency knob controls both the center frequency of the filter and the pass through signal level.
Resonance Control - In filter mode, the resonance knob controls the amount of resonance. In VCA mode and lopass gate mode, the resonance knob is not active.
LPG Mode Switch - Switch between the 3 modes of the lopass gate. VCA position (up) enables VCA mode, LPG position (center) enables lopass gate mode, and LOPASS position (down) enables low pass filter mode.
LPG Patch Points:
LPG CV IN - Frequency modulation input overrides internal routing to allow for external modulation.
LPG IN - Signal input overrides internal routing.
LFP OUT - Signal output.
