Just check that you have the correct octave for these MIDI notes. Maybe just try one of them first. Sometimes they can be an octave higher or lower than needed (due to Middle C being C3 or C4).
Also, for the time being, maybe remove the Expression Map but leave the Percussion Map.
Also, you only have two different Conga instruments in your Perc Map: Quinto and Tumba. And these have different Playback Techniques that don’t seem to be notated in your score.
Make sure you have the four different Congas as per your Percussion Kit, and that the Playback Technique is set to Natural in the Edit Percussion Kit dialog.
Otherwise, you might be sending data from your score to the Requinto or “Tumba with a Slap technique” that have no reference in the Perc. Kit.
I was able to set up the congas, as per your direction, to play in play mode, but in write mode I can’t get them to sound. Here is the drum kit setup
If so, these are the instruments that need to be in your Percussion Map, one per MIDI Note (depending on which instrument you want to trigger which MIDI Note)
Well, G#3 and A3 are only going to be triggered when you have a Playing Technique for Muffled and Slap (respectively) notated in your score, on those particular congas.
The instruments assigned to F#3 and G3 I am not sure about as they should both be triggered when playing back “natural” notes.
Do you have a screenshot of your VST screen and mappings? Perhaps there’s some confusion happening.
Maybe try routing your instrument to a different VST, one with just a piano sound would be sensible, and assign your JABB Percussion Map.
If you press play, you should hear each conga as a different pitch on the piano.
At least you will know if MIDI notes are actually being triggered or not. If any are not being triggered (i.e. there’s no sound) then that narrows down our problem.
I can’t stress enough to make sure the Playback Technique for each of the four MIDI Notes you’re using in your Percussion Map is set to Natural. This is not permanent; it’s just to help diagnose and make sure there’s a connection.
If you send me an empty project, I can even do this for you.
