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! |

Isn't noise only, but does reset noise at audible intervals: https://youtu.be/qmj-KG7CWX4?si=9IChS8pu-IJFRO2_ |

Cool idea! Waiting for the MSL pwnage as usual. :D
I tried something, but gave up, things sounded really cool in GT, but can't get the filter+noise to give me any proper notes in sidplay/vice and barely on real HW.
Looking forward to the compo though, I feel this is gonna be a good one. <3 |

as for GT, someone would have to produce a build that contains the latest reSID so it actually works like it should :) using a recent VICE should be fine (to be safe use the development build, i don't remember exactly when the last related fixes were merged) |

-I3 switch for regular GT2 run commandline enables the latest reSID it has included. Believe me, even some top guys skipped that little detail till this day and GT2 by default sounds almost as shitty as GT1 did (no difference above $60 cutoff and wrong waveform restarts to name a few). No idea how they did sound that awesome so far without having a full control over crucial playback aspects :D |

But even that version is kinda old... :) |

And closer to what I hear on real 8580 than Vice 3.8 (minus the ADSR quirks) ;) I out signal via SidFx, though, so that might affect output and my judgement. |

Last time I used it, VICE has weird 8580 filter defaults. GT2 8580 is pretty good, but is less resonant than most 8580s. Most accurate I think is sidplayfp. |

You're right on resonance. And emulation is better and better in department of actual SID behaviour but somehow overall sound colour and characteristics (which harmonics dominate, sharpness in high end etc.) seem to deviate more from real chip than it used to. |

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 ;) |
