I don't think we have changed anything related to XP MIDI recently. Can you post a very short MIDI file (just a single note is enough) that demonstrates clearly the issue ? Feel free to send it throught our support page: https://www.modartt.com/support?direct=1

I've notices there has been a change in the Disklavier XP MIDI dialect since versin 7.5. My controller is a Yamaha N1 and when I press a key slowly it produces the value "Aftertouch 127" in standard MIDI. This is an issue since I can't play harmonics over silent keypress because the value for silent keypress in standard MIDI is "Note on 1". However, in Pianoteq I've found a solution for that by changing midi dialect to Disklavier XP. When I press a key slowly in that mode it produces the value "Damper position 127" which has always functioned as a silent keypress, same as  "note on 1" in standard MIDI and has allowed for trigging harmonics when hitting other notes. Unfortunately, in version 7.5 this has changed and now the value "Damper position 127" produces a soft note and there is no possibility to play a silent keypress in the Disklavier XP mode. For me this means there is no possibilities to create harmonics over silent keypress in Pianoteq anymore with any default settings. Is this a considered change or a bug?
