Topic: Correct MIDI settings for Yamaha CLP-7xx

Hello,

I am using Pianoteq 7 with a Yamaha CLP-785. One of the features of this piano (and probably entire 7xx series) is that it models key release in this way:

- About 40% of the way up, a single poly aftertouch MIDI message with a fixed value of 18 is sent, and the internal engine makes the sound partially damped. If the key remains in this position, the internal sound dies many times faster than it would otherwise, but not instantly. Middle C might die after 2-3 seconds.
- About 60% of the way up, a note-off message with a fixed value of 64 is sent, and the internal engine almost instantly ends the sound.

In Disklavier XP mode, Pianoteq is recognizing that poly aftertouch has something to do with the damper (I'm inferring this by observing changed text with incoming MIDI messages in the settings dialog), but there is no change in the sound after the aftertouch message is sent. I believe it may be expecting higher values for aftertouch or a stream of values. I believe this setting has worked for users with AvantGrand N1 according to an earlier thread.

CC#88 mode seems otherwise appropriate (CLP-785 sends out CC#88 with note-on), but this doesn't recognize special Yamaha implementation for key release.

In regular MIDI mode, I don't see any useful parameters to map to the aftertouch message.

Is there a way to take advantage of this partial-release feature in Pianoteq?

I don't know the answer to this question, but I do know that the Yamaha NU1 and NU1x does something similar and I too am interested in such a setting (if it exists). Googling for settings related to the NU1 might bear some information, since it's probably a more popular instrument and has been around for long, if I am not mistaken.

Where do I find a list of all posts I upvoted? :(
