Flexibilit is a fairly simple module. Plug an expression pedal into it and use your foot to control your modules. By default it generates a 0-5V signal (unipolar) or a -5/+5V signal (bipolar), attenuated by the foot pedal.

Flexibilit has an input for external signals, so it can be used as a volume pedal on audio or attenuator/attenuverter on CV signals.

For when you need that extra hand!
