Karl,

Thanks for your reply.

not sure where the Knowledge Base went - or if this is accurate:

MIDIFileWriter 1.01
converts a MIDIScore into a midifile...YAY!
To load in, modify, and save out a midi file, do this:

(scorePlayerMorph _ ScorePlayerMorph onMIDIFileNamed:'inputMidiFile.mid') openInWorld.
"play with the midi file...move notes around, etc."
"when done, do this:"
mfw _ MIDIFileWriter saveFileNamed: 'outputMidiFile.mid' fromScore: ((scorePlayerMorph scorePlayer) score).
mfw writeMidi.

+++

To simply test out how squeak converts your midifile, try this out:

midiScore _ MIDIFileReader scoreFromFileNamed: 'inputMidiFile.mid'
mfw _ MIDIFileWriter saveFileNamed: 'outputMidiFile.mid' fromScore: midiScore.
mfw writeMidi.

http://guzdial.cc.gatech.edu:8080/squeakers.179

leads to the same dead end :(

this is a main point - at this point :)

btw, i have not tried sending any email to: gte356h at prism.gatech.edu - but from the mentioned dead end, i am not particularly motivated to try :(

what lead to that dead end is a further waste of time - it seems - THAT is why i inquire HERE.

i have spent time with:

mfw _ MIDIFileWriter saveFileNamed: 'outputMidiFile.mid' fromScore: ((scorePlayerMorph scorePlayer) score).
mfw writeMidi. - part...)

possibly: some, most, or all of the ingredients are there, but not for the recipe i am seeking... 

the recipe is kinda the opposite of what i want.

and even that it doesn't actually work as described - or at least as i would hope....

i can open and play a MIDI file in Squeak - no problem...

i can change the instruments in the Score (IN SQUEAK)

and
save the MIDI file...

and,

well,
the saved file plays back with the exact same instrument it was in the first place :(

the changes i made in Squeak do NOT make any difference in the saved MIDI file...meaning that NOTHING was changed in the MIDI file that Squeak produced - it sounds exactly the same.... 

and this is something i do not even particularly care about - as far as the "instrument" goes... but it does seem to be a possible "bug"... just try it: open a midi file - change the instrument(s) - save it VIA MIDIFileWriter - and see if it sounds different from the original....

Point is that everything i have found in the system (as far as what i would expect only from saving a MIDI file that was altered from within squeak merely changing the instrument) does not work...

BUT - as confusing as THAT is - IT is not what i want to do:

translate the fairly simple material from my original post to MIDI...

Thanks for your reply :)
