We organizing some small compo here and I try to gather some works from ppl who might be interested.
It will be a MOD contest for Atari 800XL / 65XE. It play MODs rather cool with 4-bit quality (under some conditions) so one can write MOD on anything - Amiga would be the safer - but the compo music will be played from the Atari X/XE, hehe.
Deadline would be 13.07.2015.
Address to send the MODs:
yerzmyey AT interia.pl
But there are some important infos:
Format -
- Amiga/ProTracker MOD (You know, PC mods play more octaves and it doesn't work later on Amiga nor Atari XL/XE).
- 4 channels,
- size of the file: up to 50Kb. No more (!!) because it will not fit in Atari XL memory (that is 64Kb of RAM).
Commands that have been ported into Atari XL (so we can use them) -
Cxx - volume
A0x - volume slide down (fade out)
Ax0 - volume slide up (fade in)
F0x - tempo
D00 - break pattern / goto next position
I would suggest to avoid the typical chiptune "very fast loops on tiny samples" phenomenon. There's no way to tell, how such a thing would behave outside of its environment (Amiga) and how it would actually work on 4-bit transducers (Pokey) played with 1,7Mhz CPU instead of PAULA chip, You know. 
It is possible we might try to release some compilation of the sent music, later. Who knows.
Well, just a thought anyway. You know the e'mail address.
Byezzzzzz,
Yerz
