Description

This device inverts the polarity of incoming sustain pedal messages.

It is designed for use with pedals whose polarity cannot otherwise be switched, such as certain footswitches from Yamaha.

Note that these footswitches are *not* common. In most cases, pedal polarity can be reversed via a switch on the pedal or by depressing it while plugging it in.

To use, simply insert an instance on the MIDI track which will be receiving sustain pedal messages.

Known issues:

This device works per track, meaning that it is necessary to add one to every MIDI track in your Live Set. A better solution would be a single device inserted anywhere which could process sustain pedal messages for all relevant tracks. This is probably possible via the Live API.
