Thanks for the help. Yes, to be specific, I am following the Tapspace article here: Virtual Drumline Tip: Integrating VDL with Dorico Notation Software - Tapspace News
Foe example, with the VDL documentation that’s on the article, it has “low tom” from the VDL Rack Combo A as MIDI note 60, note name C3 (in the article it’s programmed as C4 because it said it’s the same thing, just using different definitions). When I play that on my midi keyboard, it doesn’t sound, but it looks like when I play E4, the note sounds.
Now, when I close the file and reopen (I made sure the MIDI keyboard is on before I start Dorico), when I play my MIDI keyboard, it looks like it is sounding everything correctly from Rack Combo A as it should be, in terms of the correct MIDI notes and note names, but then when I try to write the notes in “write” mode, that all goes away, and it looks like every MIDI note is moved up a third. For instance, that low tom that should be MIDI note C4 is now E4.
Also, the only instrument that is sounding when I play it back is the snare drum. I’ve attached some screen shots in the file, hopefully that helps.
