Thanks. However, the korg MS-04 seems to be an expensive solution I'm afraid.
Maybe it makes sense to install a modification on the CS80:
Changing the external-in jack from an input to a situation that it sends out a copy of the sine-subosc-wave. Connecting a cheap, passive pedal (Tip-Sleeve, just with a resistor in it) makes it possible to control the depth of this signal by feet while changing speed by applying aftertouch. I guess this is a simple mod for those who practice electronics.
Or am I thinking to simple. Maybe you'll have to install an opamp that is fed by the sine-wave to achieve this and control the amplification of this opamp with the pedal ?
