The ".TMK" file is sort of like the Cue Sheet used in CD burning, Meta Data about the actual recorded music file
Dang, got all excited the A10 could compile turbo pascal. I rocked that language, wrote my thesis with it 😀
Pascal ! Woot-woot !
We cribbed in PL1, then onto sh, csh, and C... then some weird proprietary scripting stuff for hardware.
Still can't code my way through much, but can identify and read a bit.
The PY folks freak me out, especially the old operators stuff.
I spent a year working along side a Modula-2 and LISP programmer doing, ...go laugh, AI for the Labs.
Sooo, I assume the .TMK is encoded inside the music file itself in headers?
CUE sheets were separate and called the music file relating time to file length position, if I remember correctly.
I need to mount the card off the recorder and fidget a bit.
