HOW DO I TRIGGER GROUPS IN AN EXS24 INSTRUMENT VIA MIDI FROM THE SCORE

Question

HOW DO I TRIGGER DIFFERENT GROUPS IN AN EXS24 INSTRUMENT VIA MIDI CONTROLLER MESSAGES FROM THE SCORE - PLEASE ? WHERE DO I GO IN DOCUMENTATION AS HAVE GIVEN UP FOR TIME BEING WITH MULTI INSTRUMENT WHERE I CAN'T SEEM TO DEFINE CUSTOM BANK SELECTS BECAUSE I CAN'T FIND THAT OPTION. BUT MAYBE I'M ON THE WRONG TRACK ANYWAY! WITH THANKS

Answer 1

For those who are following this thread I have received the following info from LPH: it hasn't dealt with this through midi controllers but with key switches in a v. easy to work with fashion, though I would still like to have a result with former, if there is anybody that can give me a clear proceedure. Christian thanks for your help and if you are offay with MC's then I love to hear from you!
METHOD #1
Create a duplicate track for those instruments which you're keyswitching. Let's just focus on one instrument for now, flute. Create a duplicate track assigned to your flute instrument ("new track with same instrument/channel"). Next, copy all of the regions from the original track onto this track and merge (glue) them to create one contiguous track. Of course if you have only one region for the part, just copy the region over to the new track.
Then go into the piano roll editor and swipe the keyboard on the left in the range of your keyswitches. Then use the command "toggle selection" and hit DELETE. Now you have a region that contains only your keyswitches.
Or, of course, you can just swipe the range that the instrument plays in. Then hit DELETE. Either way...
The final step here is to untick the "score" checkbox for this keyswitch-only region (region parameters). Now, both tracks will still play, except only the actual flute part will appear in your score.
METHOD #2
In the score editor, open the staff style for the part. Set the highest note/lowest note range to (visually) filter out the keyswitch notes. This may seem like the easiest way to do things, but it will require you to have a distinct staff style applied to each part. For example, if you're using the Treble staff style for multiple parts (picc, flute, bass clarinet) and their key switches are in different ranges of the keyboard (as is the case with some libraries), you will need to create duplicates of "Treble", name them accordingly (picc, flute, b.clarinet), assign them to the various regions playing those parts, and then set their highest/lowest note values accordingly.
