Is there a sustain pedal attachment?

Yes there is an optional attachment. The electronics and software to control it are currently in place. The PNOmation OT uses QRS’s proven Magic Pedal mode in lieu of having to use a pedal. In Magic Pedal mode the notes are held down for the duration of the sustain event vs raising the damper rail. Some resonance is lost, the piano can play quieter and setup takes a bit less time.
