I’m looking for is a triple pedal with una corda, sostenuto and continuous sustain. Several NI Kontakt piano instruments support this in software, and I just purchased the S88 Mkii controller, so what pedal do I need to purchase to get this working? The Studiologic SLP3-D is the only triple pedal I can find that offers this (on/off for the left and center pedals, continuous for the right pedal), but it uses a single 1/4” TRS, and I can’t find any documentation about using this with the S88 Mkii. Help?
