Thank you for your response,
Sorry for the problem which is not precise, I use a translator and I will try to be as precise as possible.
I use a VSTi guitar from “Ample sound”.
When I program all the techniques of the instrument (which are triggered by KeySwitch) into the expression map all the techniques are triggered when I start playback. Indeed, I can see on the “piano” of the vst that the keys are activated and that the techniques are activated on the virtual instrument.
However, the techniques hammer on / pull of and legato slide, even if the technique is activated on the “piano” of the VSTi as well as on the virtual instrument, the hammer on / pull of and/or legato slide are not played. The technique is activated but the sound of the technique is not played.
The same applies to guitar chords that are triggered by a keyswitch. When I activate a Key Switch the guitar plays 3 notes of the chord when it should play 6 notes.
When I export the midi project as is in a DAW everything works normally.
I would like to point out that I have disabled all synchronization between the VSTi and Dorico.
I have tried this on several different guitars and different versions of “Ample sound” and the problem is always the same.
I don’t know if that’s where the problem comes from, but when you say: “…Dorico does not currently output tempo information, so if the plug-in relies on this information, e.g. to determine the rhythm of a strumming pattern, that will not work in Dorico 3.5”, does that mean that this problem is likely to be solved in future versions?
I hope I have been as accurate as possible.
Thank you in advance for your help.
