Hi, I've gotten it into my head to try to try to decode some files from 30 years ago and see if I can extract enough MIDI -- and perhaps, instrument modifications -- to be able to approximately recreate the audio on Linux. The files were created from a program I wrote and have long since forgotten. Using the old Korg M1 manual, helpfully scanned in by Korg, I've been able to determine that most of the files start with the "exclusive header" and can be categorized as to which type of dump they are. From there, I should be able to break apart the data. However, I have a several files with the extension ".sng", which would suggest "song", but the opening bytes are not the "exclusive header" but rather, in hex are: "00 10 00 3C" followed by a list of 16-byte ASCII strings containing instrument names (followed, for a while by mostly 00000000 and/or FFFFFFFF before getting to something a bit more variable) Skimming through I also eventually see what appears to be a "song title" in ASCII. Is anyone familiar with what type of beasties these files are, and is there a good spec for the format? Thanks. P.S. (I only had access to the M1's for one semester, and the code was written on the school's Atari ST-1040, which I'd never seen before nor have I used one since.)
