not neccessarily a user-accessible one. imo, the user shall only be able
to set fade-in and fade-out points (possibly also "linear fade" or
"logarithmic", but that's not important right now), and muse will ALWAYS
fade from 0% to 100% and vice versa.

huh? shorten the length? why would we want to shorten any lengths?

and i just found a huge flaw in my idea: there are cases where you need
something mightier.

three use cases:
1. have two lengthy tunes on an instrument which you want to crossfade
2. have a one-measure drum-pattern you want to play 4 more times while
   crossfading to a different drum-pattern.
3. have a whole piece of music (or at least, a big part of it, with
   multiple parts) which you want to fade.

ad 1.) this works perfectly fine with my proposed fading mechanism
ad 3.) this definitely can't work with my mechanism; we'd need a track-
       fading solution, but i had in mind that my feature can't handle
       this use-case.
ad 2.) hmm tricky. my feature was intended to be able to handle that.
       but obviously it can't work right now. but this will snap in with
       my second proposal (see the other mail) about templated parts.
       (abstract: you just don't have lots of 1-measure-clones when you
       want drum patterns etc, but create a "template part" instead.
       that's a special kind of part which allows you combine several
       templates (one template would be equivalent to one one-measure-
       clone-part) plus more really fancy stuff. that template part will
       be lengthy enough to do the fading you want. problem solved.


i think this feature is something between "extremely nice to have" and
even "important", though it cannot replace track-fading.
but i want it to exist next to the track-fading. are you okay with that?

true, lets postpone the visual stuff.
