Since [seq] won't play 'multitrack' midifiles, since i couldn't get detonate to work (or didn't understood how it works, also in a topic they say that it doesn't seem to work properly), neither mxj.midifile from cnmat, then i went for [ftm.play] (patch bellow), but if i change the file after playing one step by step, then max crashes.

(Also it would be wonderful to have a pianoroll moving while i bang the file step by step! :-)
