Event id #3436 : $81 Music Compo 2024
You may surely remember one of the most inventive and fresh competitions around here - $11 Music Compo, organized 6 years ago by Isildur/Samar, as well as its later $21 edition launched by Eric Dobek. As some time has already passed, why not give another waveform a little spin? Let's try $81 and MAKE SOME NOISE!
Basic Info:
- Deadline for entry submission is July 31, 2024 at 23:59:59 (11:59:59 pm).
- Voting closes on Sunday, August 4, 2024 at 23:59:59 (11:59:59 pm).
- Voting platform is CSDb but eventually votes will be processed with a trusty algorithm, proven reliable in couple of older compos.
- Main prize is CSDb fame and prestige.
Rules:
- Compositions can only use waveforms $80 and above (so it's safe to assume you gotta stay negative xD) but $00, $01, $08 and $09 will be pardoned, especially if music player doesn't give musician any other choice.
- Highest allowed multispeed ratio is 16x. With this particular waveform, multispeed is truly a handy tool to achieve more diverse results but limit is imposed to avoid threading in digis territory.
- Filtering can be freely used.
- No covers are allowed.
- Only single chip is permitted.
- Entry must be handed in as executable .prg (which might be embedded in .t64 or .d64) and additionally .sid. Preferably both ;)
- Contestants can submit as many entries as they like but entry has to be at least 2 minutes long composition - you can do better than a short test loop, right? ;) No upper time limit, though.
Rule set might expand if compo related discussion leads to it. Let's not, preferably.
Tips and Tricks:
- One of the most handy techniques for this compo is noise LFSR reset which orders noise wave to play pseudo random seed from the very beginning. To perform it, you need to write a sequence like this to waveform register - $91, $89, $81. It's very effective especially at higher multispeed ratios.
- If Goat Tracker 2 is your weapon of choice, $91 might be set already as 1st Frame Wave variable to perform restart cycle one frame earlier and not to waste wave table frames on it.
- 6581 filter distortion might turn out interesting tool at disposal if you go for the old one, especially combined with LFSR restart.
Good luck and have fun! |

It is *much* closer to real chips than it ever was before.
And filters are different. On every chip, and even every different hardware. Usually Caps have 10% Tolerance to begin with. Etc pp.
In any case, if you expect ancient emulation to be useful for this compo: good luck :) (edit: that applies to both reSID and reSIDfp - that LFSR fix was only applied recently to both) |

I assure you I'm hardly any surprised while checking stuff on real HW ;) ADSR quirks and oscillator leak were honorary exceptions ;) |

Not sure what you are trying to say :) |

Jammer: can you point out a tune that sound different on real 8580 than on recent VICE 8580? I'd love to check that out. I'm not as versatile as you in sound programming, but it would be good to know anyways (maybe for the future) :-) |

(pls open another thread for VICE bickering, preferably even report the problems the proper way)
More on topic: https://github.com/LeifBloomquist/VICMIDI/blob/master/Docs/wave..
Something along these lines is probably doable using SID too |

Seems to require speeds over 16x, though. |

Yes, i doubt anything interesting like that can be done with regular players. |

i have created something in goat tracker that sounds like a chopped-up fm-didgeridoo, but in sidplay, it sounds like merzbow recording himself munching on a box of weetabix. which version should people base their vote on in the end? :) |

Eh, people of little faith ;) Whatever Groepaz says, setting or not setting I3 in GT2 makes night and day difference in what you get as a preview. |
