A true beast of a dual osc to serve as the core of any MOTM system.
The 3 PCB Set consists of two main OSC PCBs and a Control PCB.
Included in the kit is the panel, 3 pcb set, all pcb components including the SMT voltage shunt, pots, switches, jacks etc.
This is a moderate to advanced build. there are ~450 pcb components including one SMT part. The build guide will walk through assembly step by step.
The module, as described by the designer, Dustin Stroh:
“The VCOs I'm calling "MirrorCore". It's our take on the internals of a CD4046 VCO, only built out using separate components. The CD4046 VCO didn't have high linearity for tracking in mind, so we've improved this significantly. I call itMirrorCore because it uses two opposing sawtooth cores, which is able to generate a perfect 50% square wave.
One of the more unique features is that we expose a logic level unipolar output, which can be used for clocking and logic purposes.
Features of the VCO:
Coarse/Fine tune controls. 1V/Oct input (high tracking range) Linear FM input PWM control PWM CV input VCO/LFO switch
