Quantize Conductor Track Disklavier

[Anthropy]

I'm helping a studio calibrate it's Yamaha C7 / Disklavier. The software in the Disklavier is apparently 'fly-wheeling' incoming data, and it doesn't like sudden tempo changes, like tempo curves.

Is there still no way to thin or quantize tempo and other Conductor track info? That would solve a problem we're having, I hope - I pray - I'm pretty sure...

fyi, that's a Yamaha 7 foot grand piano that's controlled by MIDI. It has a built-in disk fed midifile player that apparently needs to be in the loop between external MIDI input and the solenoids that make the key hammers and pedals move.

Here's a pro tip if anyone is using such a machine and are getting thunderous pedal sound: instead of cc#64 values being Zero or 127, nothing in between - you can subtly slow that pedal down by putting the MIDI window in Lines mode and creating pedal slopes like these in this screenshot.
