Event id #2967 : 25Hz Music Compo 2020
Welcome to the first and hopefully not the last edition of 25Hz Music Compo!
Basic premise is to create a piece of music with player that updates SID registers at rate of 25Hz or to put it in other words - every 2nd frame. There are very few tunes out there playing at such slow speed but maybe it's the right time to change it? :) Here are couple of examples:
Low Frequency
Half-Funk
Compo rules:
1. No covers and remixes allowed.
2. No upper limit for playtime.
3. No limit of tunes per author but playtime of each has to be at least 2 minutes.
4. Use any editor that allows you to use such playback rate or go for custom player if you need. Goat Tracker surely offers 25Hz playback (Multispeed 0).
Good luck and have fun! <3 |

I guess it's not a problem for entries which just do play/don't play logic per VBL ;) |

That one cycle (not line) per 2 frames wont matter at all =D |

well, just run Webchat and see the raster bar going down progressively as the tune plays. |

Would it be acceptable to update the driver at 50Hz, if the driver only outputs to the SID every other frame? |

I suppose you mean player call rather than proper update. In that case sure! Unless you mean updating some internal player variables per VBL - but I cannot think of any potential benefit to that solution then :D |

imho it only makes sense when you call the player at 25Hz.
ian: if we really want 25Hz, not "every other frame"... those are different things =) |

You didn't get my answer. I questioned what would be benefit of updating player at 50hz but updating sid registers at 25hz instead of doing everything at 25hz ;) |

How would that differ actually? We're strictly talking about SID update frequency. |

Framerate is 50.125Hz, not 50Hz |
