Announcing the "General CV"

1st April 2017 - Expert Sleepers announce a new Eurorack module, the General CV, which places a full General MIDI sound set under CV control.

"For too long, Eurorack users have been denied important sounds such as 'Voice Oohs', 'Orchestra Hit' and 'Shakuhachi'," says Expert Sleepers founder Andrew Ostler. "We're delighted to finally bring these classic tones under CV control where they belong."

The General CV will show at the Superbooth show, Berlin, in April 2017.
