The Timbales channel in the attached project is not working correctly for me.
I can’t adjust the velocity of the notes and the fader in the mixer doesn’t change the volume. I’ve tried creating a new player as well as reseting the playback template. Edit: if I change the playback template to Silent, the velocity becomes editable.
The timbales are two instruments. You can change the velocity or use the fader for the Timbales 1 (orange) or Timbales 2 (yellow). To see them in the midi editor correctly, you need to expand the Timbales (red) in play mode.
Routing for percussion kit components. Each individual unpitched percussion instrument included in a percussion kit now appears as a separate track in the track overview in Play mode, making it possible to select each instrument and change the settings in the Routing section of the track inspector panel independently.
This restores functionality that was present in versions of Dorico up to 3.5 that was temporarily removed as a consequence of the rebuilding of Play mode in Dorico 4, allowing each instrument in a percussion kit to be routed to a different endpoint if necessary.
It is related but it doesn’t explain why I would be able to edit note velocities and adjust VST faders correctly on the Congas and the Drums: both of which contain 2+ instruments. (I just opened my original project to check).
The fact that the velocities snap to zero indicates that there’s a problem with the routing of those instruments. I’ll need a bit more time to look into this, as this stuff is all a bit complicated, so I’ll come back to this when I can.
In the meantime, you can edit the velocities using the Velocity property in the Properties panel.
If you check in Play Mode the Endpoint Setup of the Timbales:
Timbales are Channel 1
Timbales 1 are Channel 2
Timbales 2 are Channel 3.
In the Halion Player:
Channel 1 is Latin Percussion
Channel 2&3 are [GM 129] Stereo GM Kit
This seems to be the standard for Timbales, even if you create a new project. Bongos are only [GM 129] Stereo GM Kit
BUT
The Latin Percussion isn’t used by the Timbales, you hear. But it belongs to the Fader and the velocity in the Key Editor.
Simple fix
Assign the Timbales to a [GM 129] Stereo GM Kit and you have a working Fader and can edit the velocity.
Why it is like this? I don’t know.
edit
Interestingly enough, if you switch to Channel 2 and back to Channel 1, the Timbales will use the Latin Percussion but of course with wrong sounds.
Basically Dorico will always assign the GM kit even when it doesn’t need to, and this can create issues. This is something we know needs to be addressed, and it’s on the backlog.
If you do get a chance to look into this more at some stage: Dorico 4 has been semi-regularly not playing back and then hanging on the Audio Engine when reopening the program. Upon Force Quitting the program and the VST Audio Engine, the project usually loads as expected.
This has only happened since I started fooling around with the Timbales routing etc. trying to solve the problem at the beginning of the thread.
Diagnostics and Spindump attached. (VST Audio Engine said “not responding” in the Activity Monitor.
