midi 2 sid

If i have a 3 voice midi file, is there a tool to convert this to some sort of prg that i can load in a c64 tracker? What would be the most efficient way to achieve this kind of result?

And if there is, is there also a way to do it with 4 track midi (1 track for samples) and import that in a 4track sid+digi tracker?

Thx

b/c i want setup the notes and global framework of a composition in a midi sequencer, port it and then start painting on the sound from a c64 (or goat) tracker format.

Efficiency is everything.

If one would feel tempted to write such a tool, even though it's just the notes and everything quantized and works online for a midifile that is strictly organised in prescribed way (so all quantized notes and only choose of some fixed tempos etc), then that would be really really cool.

never done that myself but it should be possible to convert a midi file to .mod format (google for mid2mod). the goattracker package contains a small tool called 'mod2sng' ... try to guess what it does :)

As far I can remember this tool only converts the notes but not the 'effects' (like the pitch wheel...)

I am actually working on something that's semi-described in this thread..

The process I'm working on takes midi files and breaks it down a bit... the second part takes these broken down text files and puts them into a small music player routine I made.. it's very very simple but is getting better. Having some trouble with the quantize function but it's improving.

Try these out if you're interested... They were the first few songs I used as samples, before starting to work on the quantize part. The newer stuff is tucked away safely :)

And here is one of the original midi's before the conversion...

I think it's advisable to compare the 2 methods: convert with mid2mod and mod2sng, and convert manually. I doubt the tools will be more efficient than manual labour. (Personally I find working from scratch far more efficient than improving on a rather badly converted (because of limited possibilities of the tools) song)

hey, sounds like a gread project... few things though...

In the SMB track, the notes sound a bit...false...
and in the LoZ and Tetris track, the bassline is out of sync with the melody... or maybe my coffee isn't working yet =D

Yeah that's actually what I'm working on right now, sorting out that stuff that gets out of sync! (the quantizing stuff mentioned above).

The thing I'm currently trying to write goes through all the sound data that has been generated, figures out where the beats are and tries to adjust the timing of the song to prevent it from going out of sync.

If a song consists of 8th, 16th, 1/4 notes, etc, my process is very accurate. Once a triplet gets introduced, things start getting out of sync, as you can hear in the songs above.
