How to mute the voices of the SID?
Hi!
I want to remix my favorite SID tunes. A lot of them have nice rhythm, ideas and melody, but if I hear them more then 10 times in a loop, I get dizzy.
I want to bring more stillness and a different temper in them - making a remix.
My idea is to mute one or two of the voices of the SID and additionally fiddle around with some registers.
I did that with emulators like the C64debugger("24Hours Demo Remix" on YT) and the result is quite nice. Now I want to do it on the C64 itself.
As I am no SID programmer or musician, I have no clue how to do it on the real machine.
I understand fundamental assembly coding, but I am far from doing fancy stuff.
So I need your help! |

After a lot of coding, testing and debugging, it is time to go live!
I released the first demo using muting and manipulation of two sid chips.
All actions are recorded during a live session.
The recording is played back and gives the demo.

Do mashups of sid tunes. |

This first one just takes one Sid tune. So I call this a remix.
SID Mashup needs at least two of them. The next step!
I can do this by extracting „samples“ from one song and play them vs another song.
Would be nice to have BPM in HVSC to find matching songs. |

I'd just make the player run on timers so that you can change the call rate for each sidtune. This way you can choose your speed for each tune. Many will sound wrong, but hey, it'll be interesting and different. :) |

Uuuh, never used timer.
From the CIAs, right?
Can I set a timer and let this trigger an interrupt?
I think this is a great feature to add! |

Funny, I just added SID voice muting and fine speed control to the SID player on the TeensyROM, then someone pointed me to this thread. Source code is in the GitHub if you're interested, here's a demo vid:

Thanks! :) |
