Thats Step One. That allows the HS to receive the Channel Aftertouch messages in the separate MPE channels and connect that up to almost all patches.
Step Two :
You can also handle other MPE controls that get sent. In the Mod-Matrix are the Modulation sources MPE-X, MPE-Yabs, MPE-Yrel. There is also Note Velocity OFF, which i am pretty sure is available in MPE form.
MPE-X is MIDI pitch bend ( En ) in the separate MPE channels. This is 14 bit data.
MPE-Y is MIDI CC #74 again in the separate MPE channels. The abs one is treat as 0 to 127, the rel one is treated as -63 to 64.
Note Velocity OFF is MIDI message ( 8n ). I think it is a dimension available in some MPE streams.
You need to be aware of what MPE data your controller generates. I think the Linnstrument can do all the above, but that is just my half informed opinion. I don’t know about Velocity OFF.
I am off-hand not aware off any pre-made patches with these MPE hooks already in place. Maybe there are some out in the Vast HS Patch Universe.
But more likely you make your own. You can go from scratch, but i’d recommend modding existing patches you already like, it should be pretty easy.
What i would do is look through the Macros for your favorite patches, and find Macros that would be good to modulate with either X or Y. Then use the destinations those Macros affect, and add them to the Mod-Matrix for the MPE-X and MPE-Y controls.
NOTE : The MPE X and Y are only received by the HS, you can’t generate those messages. Note Velocity OFF can only be generated by the new HSs, the Explorer and the Deluxe.
