11 line polyphase music generation with atari basic

Dec 8, 2022 12:45 AM

11 lines of basic programmed on an #atari 800 that generates a polyphase melody from a 7 note sequence.

Put that into a DAW, add reverb and automated notch filter, and you got perfectly good sounding IDM track going.

You even used the peek/poke commands. Nice.

It's been a loooong time - but lines 10 and 11 are superfluous.

oh, and i maybe i put the last line in so that when i hit break, i could just type goto 11 (or was it run 11?) to get the sound chip to stop

omg! you’re right! must have put them there for reference… maybe while i experimented with different values? a 9 line program- even better!

I remember doing this on the Commodore 64's at the public library computer lab in the early 80's. I'm old.

I had a SID chip program called Ubik's Music on the C64. Had to enter note length in hex. Not the quickest way to compose

Commodore had the SIDD chip which made music much easier. I too, am old; and a musician by hobby. This is what gave me the bug.

I remember coding these on the Commodore 64 and saving it to a cassette tape. Then I got the commodore 128 and a floppy disk. I am also old.

We should all get together, yell at people on our lawns, and talk about music.

I am also old. But I programmed on a TI-99. I had no way to save stuff (pops wouldn't spring for the cassette memory set up).

TI-99 and Atari 600XL were my first tools. I wrote many programs that were simply turned off. Until I finally got a tape drive anyway.
