This is how I see it.
Tracks are gathered by going to labyrinth of folders and files for every generation...
and Tracks are obese (large)


If the all active (mixer) tracks are loaded into memory or at least copied into single folder, probably should make things faster. Also, for the chording and previews I do not mind split Mono tracks, which again I believe should make things faster because size of the files are reduced to about 1/2.

We can try to guess these things until we turn blue smile Still it has to be the oracle who can give a green light to explore the possibilities. Meanwhile, I want to wish Happy New Year to all people who are frequent at this section of the forum and who refuse to give up, bringing excellent ideas, even when it seems a one way communication.
