compact well specified audio VCO for MOTM and MU based modular synthesisers
The 'A' variant has a single tune control and three way octave switch. While the otherwise identical 'B' variant has an inc-dec switching system (with three way momentary switch and LED ladder display) to allow for easy control over five octaves and a wide range LFO setting.
SVCO-A modules are built with just the SVCO main board. The B variant uses the same SVCO main board with an additional SVCO-B daughter board that attaches to the main board via a tidy 10-way ribbon cable.
Both variants have a variable width pulse wave as well as a sawtooth waveshaper to generate a fully varying shape from ramp through triangle to sawtooth.
The SVCO uses a sawtooth core but with a different topology than our existing double width VCO. Hard synchronisation is possible from an external VCO. Expansion to a double width module would be possible to allow for further input and output capability.
To allow all the functions required by this module we have had to reduce the spacing between the pots. Instead of our usual 1.625" (41.3mm) we have opted for the smaller 1.375" (34.9mm). Used in conjunction with smaller 20mm (13/16") diameter knobs this still allows for an attractive module design and finger friendly tweaking.
These merchants probably sell this module. Huh?
