Highest times-x speed of SID tunes?
Hey there,
especially in older tunes you encounter double/quad/whatsover speed. I wonder what is the highest figure. AFAIK Barbarian is 8x speed. Is there any tune with a player routine that is supposed to be called even more often per frame?
Thx in advance

nope, that's 8x
23C5 A2 09 LDX #$09
23C7 8E 05 DC STX $DC05
23CA A2 98 LDX #$98
23CC 8E 04 DC STX $DC04
CIA setting are calculated this way: ($4cc8/8)-1 = $0998 |

Interesting thread mates.
I may be dead wrong but as far as I can remember, back in time when Hermit coded the 'rakBIT' SID remix album interactive album cover that was a good old C64 music collection, he told me something like that his SIDRIP tool that reads the SID registers from clock to clock reported some extra wicked multispeed player code for Martin Galway's TIMES OF LORE title tune, the one that sounds like a real guitar. I can't recall it clearly but as if we talked about some 16x player or something.
iAN what do you say? You know the players inside-outside.
The rakBIT music colly includes a Richard Joseph tune, too, called 'Rimrunner'. I still can't recall clearly as Hermit told me a lot of code tech stuff that I could not really understand at the time but it was maybe an another multispeed tune, with extra wicked player, eating almost all the rastertime available. But maybe not, it might have been Galway's Times of Lore?
Check the album cover colly if you like, both tunes are included:
rakBIT
These are not the original SIDs in it but the bytestream player. |

Galway's Arkanoid is filled with multi-speed sounds at least. :)
I think Barbarian is 8 speed.. resulting in not too obvious multi-speed sounds, but a great tune overall. |

Barbarian is almost ancient - 1988.
Maybe these records you linked need to be checked. |

I agree mates, Barbarian is a gem. All of them above IMO :) |

Arkanoid is multi-speed if it comes to sound-fx, and the samples are generated realtime (at ultra-speed), which sounds alot cooler than the alternative drum sampled version. |

Some more of Galway's songs are multispeed: wizball (and maybe parallax)
Check with my sidplay and you get a visual :) |

Great tool, so Electrosound is the first nitro-speed music when it's going at high BPM? :) |

nitro sure is below ultra - why not go for hyper?

Yeah Wizball is QuadSpeed and another one of my alltimes favs by Galway, Times of Lore is double speed NTSC clock :)
@6RG: I began coding a smilar tool (mainly meant for own usage, but maybe to be released some day, who knows, coding that was the main reason why I opened this thread) before I found yours on HVSC page a few days ago. Great work you did in Sidplay64 v0.7, anyway.
@Jeff: \o/ Thx for the self-promo, didn't know that one before, great percussion :) |

Hey there,
thx again for your help, everyone.
Do you have any idea why I fail to calculate the speeds of Wizball and Times of Lore properly as Ian had explained thus
23C5 A2 09 LDX #$09
23C7 8E 05 DC STX $DC05
23CA A2 98 LDX #$98
23CC 8E 04 DC STX $DC04
CIA setting are calculated this way: ($4cc8/8)-1 = $0998
All the other tunes' speeds can be calculated with that formula by halting the timer, initialising and dividing #$4cc7 by #$llhh of the timer values $DC04/05.
Of course I do know their real speed and both songs of course do play in the correct timing in a CIA-timer-IRQ, that's not the problem, but I really wanna calculate their speed and fail :)
Thx in advance if you have any idea.
CU
Ryk
PS: just a guess: could it be possible that they turn on the switched off $DC0E again even when initialising so that my values are f--ked up? |

there was a time where cia timers were set in the play routine each time, instead of once in the init as we usually do now. The important thing is that the CIA generated IRQ happen at specific and constant time to have equal distance between play calls inside a frame. It happens rarely that 2 calls but be at a different and irregular distance, so the CIA timer method won't produce a sound as intended, so the actual raster pos must be used, either with d012 polling or multiple raster IRQs.
I don't see the need to use the old method so I simply stick to the new one, just set CIA in init and it's done. |
