Multiple CC64 (Sustain) Messages (One Pedal Press Sends a stream of events)

archetipo · March 4, 2026, 10:23am

Hi everyone,

I recently replaced my old Yamaha controller (a digital piano that I used as a master, just turning the volume down) with a proper master keyboard: a Kawai VPC1 with the triple pedal unit.

Since switching, I’m experiencing an issue with the sustain pedal (CC64). Instead of sending a single message when I press the pedal and a single message when I release it, Cubase is receiving multiple CC64 messages for each movement. Basically, one press generates a stream of sustain signals instead of just one on/off message.

Pic one shows the cc64 sent by my old Yamaha, pic 2 shows the mess sent by the Kawai

Has anyone experienced this before or can shed some light on why this is happening and how to fix it?

Thanks

Yes. Your digital piano supports half pedal. It allows the sustain pedal to be partially pressed just like you can on an acoustic piano.
So in other words, there’s nothing wrong and nothing to fix.

Thanks for your reply. By “wrong” I mean that if i have to edit the sustain of one chord I’d have to deal with a million dots.

You could try “MIDI→Functions→Thin Out Data”, that should help a bit.

An alternative to Thin Out Data is a Logical Editor preset like this one:

Thin Out Data applies to all events in the selected/opened part. This LE preset only applies to selected Controller events.

You could also create an LE preset that deletes any CC64 event that is NOT 0 or 127 if you want your sustain pedal to become binary.

It actually doesn’t if you select only the CC data points you want to thin out beforehand, but that can admittedly be a somewhat tedious procedure (even more so as I just realized that you cannot use the “shift-double-click” method as on automation data to select all CC data points…)

I tested in the Key Editor before I posted.

With this CC 1 selection, the Thin Out Data command applies to all MIDI CC data.

Yes, you are right, I mustn’t have checked very precisely (and I had “type of new controller events” on “ramp”, which isn’t the best setting to test that anyway…).

It isn’t the best setting, period.

Just for grins I asked AI, they said:

A pedal calibration tool was introduced in VPC Editor v1.4, allowing users to calibrate the minimum and maximum values sent by the F-30 pedal. This is intended to ensure the full range (0–127) is covered and to correct for hardware tolerances, but it does not convert the pedal to a binary switch"

And gave a reference of: www.kawaivpc.com

Beyond that sliver of a possibility it might help you (set min/max = 127, e.g.,), AI said any fix would need to be external to the keyboard/triple pedal.

Hi there Alexis, I did try the pedal calibration (i have the latest Kawai editor, which is V1.5) but no joy. I wouldn’t disable the half pedal either, as I do need to use it in my recordings. It’s a bit of a drag

The positive bit is that I’m in awe with the VPC1 keys action. Closest touch to a real piano I’ve ever played (and it’s a 2014 product !
