Hi,

I'll look at this one day; FWIW it's confused because it thinks
that Noisecontrollers, TBA, jordykiller1, ... are variables you try
to substract from each other.

yes; if you need midi parts to be synchronized to audio parts, you
have to tell the audio player to expose its clock and to midish to
use the external clock, this is the hard part

the "import" function creats a empty project and loads all tracks
of the .mid file. So importing a new .mid, discrads the previous
one. Then "p" starts playback abd "s" stops it; basically that's
all. There a "batch mode" (usefull for scripting) where "p" stops
automatically at the end of the song.

Take a look to the "smfplay" example script.

Sorry, there are no such filters. Most of the filtering is about
changing controller numbers, transposing routing between channels
and multiple devices.

There's a way to progressively quantize a track, but that's the
opposite of what you need :(
