Richard Russell's 1980 Music compiler for CP/M

This comes from the guy who wrote BBCBASIC and it was one of the incentives to make an I/O board for the Playground. Back in the day I had this running on my Ferguson Big-Board CP/M box, and at the time - before Soundblasters, Audacity and AY3-8910 'chip-tunes' - it was quite a showpiece with its four-part harmony and wide tonal variation.
It was featured on CP/M Usergroup UK disk 13, which is archived here:
Tune files are written with line numbers like BASIC and I recall spending over a week coding 'Stairway to Heaven' now long gone on discarded 8" disks.
The programs hardware requirements are simple - all it needs is one 8-bit port and a digital-analogue converter. I used my old SounDAC.
The pieces are truncated as a lot of the tunes are full length – a long time!
Cheers
Phil
EDIT: I’ve just found a later version of this compiler, along with a few more tunes – its on CPMUGUK disk 50:

Smart bloke, that Richard Russell. He's still developing cross-platform BBC BASIC and pulling impressive bits of old tech developed at the BBC from his attic

Cool getting four voices out of such a limited system and still sound clean. Video would be much more interesting if you talked about what you were doing while doing it. Voice over narratives are far more compelling!
