This Module is currently available.
VCO / LFO
It features Linear AC and an Exponential FM inputs with attenuators, one Hard Sync input and a 1V / Octave tacking input, output and offset switch.
Connecting a signal to the EXP FM input will change the pitch of the oscillator.
The H-Sync and FM functions produce a full sound, and it octave tracks very well.
This VCO features four waveforms: Sine, Triangle, Ramp and Pulse wave.
There are trimpots for 1Volt / Octave tuning, High Frequency tracking, and Ramp wave connection. There are two trimpots for the sine wave: one for roundness and one for symmetry. The roundness trimmer also adjusts the amplitude of the sine wave a little.
This 7555 VCO also features a 3-way switch providing 3 frequency ranges: MID, VCO and LFO.
The back of the module allows you to 'pre patch' various functions.
