Recently, I find great difficulty using my MIDI keyboard (Nektar Panorama) to enter notes for electric bass. I do not believe there is any problem with the keyboard, as I can use all the keys (notes) as expected when running to the stand-alone Keystone Classic VST.
I never noticed this problem until several weeks ago. Here is what is happening. I can create a new Dorico score containing only a 4-string electric bass. I play MIDI notes chromatically starting with F downward. When I get to Db and C, those notes are missing, and never reach Halion Sonic.
I vaguely recall setting up MIDI shortcuts a long time ago. And I very well could have assigned commands to the C and Db, because, depending on the octave shift, these could have been the bottom two keys on my MIDI keyboard. But I am 99.99% certain I have done bass entry with MIDI many times since then without difficulty.
I am trying to check for any MIDI shortcuts under Preferences → KeyCommands
When I hit the Db, I see NOTEON37 appearing in the key command menu. Likewise for C and NOTEON36, so Dorico is definitely receiving the MIDI note, but not passing it on to Halion Sonic.
How can I find if there is a KeyCommand assigned to these MIDI notes? Is there a JSON file or something to look at?
Another peculiarity is that sometimes when I am experiencing this problem, the patch changes from electric bass to some vocal sound, but I don’t think that shows up as a new patch in Halion Sonic.
