I doubt this is gonna be easy... maybe you should put a C++ coded converter as a middle step, for the processing power...

I think it will have to written in a "grown-up" language    but in concept it could be failry simple - read midi file - split into midi tracks - and then the hard bit - write it out as a Scratch sprite!

Writing it out as a Scratch sprite is definitely the hardest part. I'm not sure if it's possible to do it in something like Python and not in Squeak itself, but I might go have a look! 

Go blob8108 and bobbybee !

I'll get onto it.

Scratch has a built-in MIDI player. It is inherited from Squeak.
You need to Shift-Click-R before play.
Then open "file list" from "World" menu and select the midi file.
To play it, choose "play midi file" from right button menu.

It requires some mods to convert it into blocks.

I've thought that actually I could get 80% of what I'd like by just having a midi reader program produce a text file like

Set Instrument to 1
Play Note 48 for 0.5 beats
Play Note 50 for 0.5 beats
Play Note 52 for 0.5 beats
Play Note 48 for 0.5 beats

etc

50% completed.

One way would be to make a parser within BYOB (Scratch would be too hard) that reads a string (generated by a "grown-up" language) and plays it in Scratch language. It would have to work something like this:

Get a string that looks like this:
P(1,A,2,B)G(1,R,2,B)
from a Java/C file.

Read it as: INSTRUMENT(DURATION,NOTE,DURATION,NOTE...)INSTRUMENT(DURATION,NOTE...)...

Parse into a list of lists of lists, with arrangement:
Each item in the "big" list is an instrumental track. Each instrumental track is a list of notes. Each note is a two-object list of a duration and a note.

Finally, you'll need to convert that into a list of scripts rather than instruments, then launch each script.

It'll probably take a while, but it'll simplify the "to Scratch" conversion to a "to String" conversion.

@abbe - great effort :-)

Seems to work on the Frere Jacques but  struggling to get it to work on others 

I'll try more variations and see when it hits problems

But fantastic work !

That's great to hear!
