GEM and MIDI using APL.68000; help

It is, only it's not documented. Just specify the appropriate port
number (3, I think). APL.68000 won't be fast enough for real-time
musical applications; you'd have to write an own auxiliary processor
for that. The neat thing about ARBIN is that you can read any amount
of data in one chunk without worrying about buffering. I had no
problems writing a soundbank manager for my synth.

Yes. There is a low level interface. (Well, you can't do raster
copying or anything requiring absolute pointers.)

Quite a lot ... especially user-defined windows. There is no generic
way to call AES functions except from an auxiliary processor. I
haven't tried much of that, though.

gdat supplies quite a few tools for writing Window/Menu/Icon-based
applications, in particular, a fast editor package. You should
contact them (they are not on the net, unfortunately).
[Perhaps you should take a look at the APL.68000/MWC interface I posted
recently.]
