I was wondering, by the way, how the hell can I change the avatar here. ;)
I'm Mister Beep. I make micromusic/chiptunes but it's not typical micromusic. It is ONE BIT music made using TIMEX 2048 (48Kb of RAM) and its BEEPER.
The BEEPER has originally just 1 channel of sound (square wave only, no volumes) but 3,5Mhz CPU's activity gives it from 2 to 9 channels, various modulations, drums, digital sound, even 16 volume-levels etc. Still only 1-bit of course.
This is my stuff http://mister_beep.republika.pl/music.html
(MP3 music, games and demos for 8-bit computers - with 1-bit music, certainly ;) ).
