Looking over the specs I see that, in addition to the new expression pedal input, the damper pedal input is also TRS (for half-pedaling) and it has a connector for the Casio 3-pedal unit - which also has a half-pedaling damper, sostenuto, and soft pedals. So.... just how flexible is the implementation of all these pedals? Can all 5 be used simultaneously? I assume the damper pedal input can be freely assigned to another CC#, providing 2 - count 'em! - 2 expression pedal inputs! With the damper pedal on the 3-pedal unit handling sustain (CC#64), can the other two pedals be freely assigned to other CC#s or transport functions - like start & stop, pattern advance...? Can all 5 pedal functions be filtered individually, on/off, by zone? By midi channel? I'd love to get rid of all the midi pedal gizmos hooked up to my PX-5S!
