YuSynth VCLFO V1 Module
The VC-LFO is an utility module whose goal is to generate slow rate periodic signal that can be used to control/modulate other modules. The oscillating period can be varied from minutes to ms, that is from subaudio-range (0.01Hz) to low audio range (100Hz).
Yves Usson designed the VC-LFO that can be implemented into two variants. In fact these use the same PCB but some part of it is either used or not. This was lead by his choice of using single width DOTCOM panels for the VC-LFO. Unfortunately, all the features cannot be made accessible on a single width panel, that's why he made two versions of it, each of them giving access to different features.
VC-LFO1 has one FM input and four direct signal ouputs (SAWTOOTH, TRIANGLE, SINEWAVE and SQUARE) and an inverted signal output that can be switched to the following signals : OFF, SINE, TRI, SAW, RAMP and SQUARE). A toggle switch makes it possible to change the range : up 0.1Hz to 100Hz, down 0.01Hz to 10Hz.
