What Makes a DAW Guitarist-Friendly?

[Soundwise]

I use the Jamstik MPE MIDI guitar (which is definitely the best I've found). Unfortunately there seems to be an ambiguity in how Studio Pro's MPE handles info from MIDI guitar. It works fine with individual sounds, but channels can get scrambled with multi-timbral instruments when you want to assign different strings to different sounds. Some other DAWs handle this with a workaround.

My workflow is more software based. Normally, I use a score editor (GP8 for guitar music) to compose, then import MIDI into DAW, use Ample Sound instruments for guitars (as they support the GP format). I wish I was able to use other guitar libs as well within the same workflow in FSP, but that requires meticulous edits with multiple library-specific workarounds to sound convincing enough. Simple MIDI channel assignment per individual notes would speed the process up significantly.

Regarding MIDI in general, this isn't a Studio Pro issue but an industry one.

From software developer's perspective, if a MIDI event is treated as an object, it is bound to have a bunch of properties, including MIDI channel number. I think, the problem lies in the event pipeline implementation, which, I assume, could be inherited from the Kristal engine and is challenging to improve.
Regarding the industry MIDI standard in general, this was eye-opening. Thanks for sharing your insight!
