Topic: Microtonal tuning from Dorico has stopped working in Pianoteq 9
Dorico 6.2.20, Pianoteq Pro 9.1.0
Pianoteq 9 as a VST plug-in in Dorico does not play the microtuned pitches notated in a Tonality System in Dorico. MIDI Tuning is set to 'Yes' in Pianoteq. None of the four options in Dorico Expression Maps - Auto, VST Note Expression, Detune, or Pitch bend - work. Changing the Playback Template doesn't help.
However, Pianoteq 8 works, as always. This implies that in Pianoteq 9, the VST tuning method that Dorico uses is broken. Or perhaps something now goes wrong when Pianoteq 9 is opened as plug-in in Dorico.
Pianoteq 9.1 does respond to MPE, MTS-ESP and single-note-MTS tuning in a DAW, using external apps, plug-ins and controllers. As far as I can tell, VST tuning in Dorico is the only microtonal feature that has stopped working.
