[CM] importing

[taube at illinois.edu]

speaking of importing, trunk now has a new function midifile-import for importing values from midifiles. its documented in res/doc/cm.html (in the Midi In section). i could add more stuff to it but its already quite useful i think.

> (midifile-import "foo.mid" 1 'key)
(60 72 44 ...)

> (midifile-import "foo.mid" 1 '(time dur key amp))
((0.0 0.1 60 0.5) (0.1 0.1 72 0.5) (0.2 0.1 44 0.5) ...)

> (midifile-import "foo.mid" 1 '(rhythm key vel))
((0.0 60 64) (0.1 72 64) (0.1 44 64) ...)



also i branched a (stable) 3.6 line so trunk is now the development line for 3.7. if i have time and patience i am going to try to add  a native sampler that you control from scheme, ie realtime triggering of audio buffers  that does  fullmix, vkey and expandn sorts of things in realtime.
