My sustain pedal will trigger the sustain but needs to be stepped on again to stop the sustain.

This doesn't always happen.


What do I need to do to make sure the sustain is only sustaining the note while the pedal is being held down?

(For example in a Korg Triton I need to go into global settings and change the polarity.)

Thank you for your help.

Ableton - your tech support is excellent.

Sustain pedal values need to be:

pedal pressed: CC 64 = 127
pedal released: CC 64 = 0

There are four options to change this:

Most pedals have a physical switch to reverse the polarity.

With some pedals, switching the polarity might work this way:

Plug the cable in while pedal is pressed.

Unplug the cable while pedal is pressed, then replug while not pressed.

Reverse the polarity in the editor of the keyboard/controller to which the pedal is connected.

A MIDI translator (www.bome.com, http://web.mac.com/nicowald/SubtleSoft/MidiPipe.html) can be used to reverse the polarity.
