How many BPM is a C64 or HardSID ?

[03:19] <rambones> any geniousses ?
[03:19] <rambones> how many bpm is a C64 raster irq ?
[03:20] <rambones> or as i this case. the music is at 51 hz... so i wanna find the sync to the beat

See. i wanna sync a sampled sid to the tracker..
So... it was sampled with HardSID which is 51 hz..

It must be around 120-130... but i am uncertain..

No clue what to google for

Perhaps you should use some shorter samples... Long sequences aren't ideal for remixing - use shorter loops instead...

On second thought (I'm a little rusty here, so bear with me) you could try to cut up your sid with recycle, but I guess the usefulness of this depends on your sequencer or whatever you use...

What VIC said. try cutting the sid into smaller chunks. works like a charm. You dont have to hit the actual BMP of the sid 100%, since it "resyncs" on every sequence

Like i explained:

When cutting sid sample to smaller bits, that are beat perfect..

If i have 10 samples, and they are played at
step 1-20-20-30-40 etc. f.ex

Then they sync to themselves, ok!

But the 0.xxxxxxx out of sync frequency, does
that no pc editor (tracker, multitrack editor, whatever),
that it cant sync with it.

It will sound ok to most, but to a musician who is trained to hear total sync, its clear it is buggy.

Ofcourse, if i did multitrack copy pasting of samples, and
spent like many many days on each bit, i can edit out of all problems. but this is too much work really.

Perhaps it is possible to make a sidplayer where you use 1mhz update as override to the 0.xxxxxxx - so that the sample will be synced with any modern editor ??

Like, just patch sidplay 2, to produce output at exactly 1.0 mhz !???

EDIT: i confuse myself...

To make a stable sample, with 0.0 offbeat variance, what is needed, and can it even be done ?

It dont matter that the sid plays not as on c64. it will be so close it dont make a difference, at least for 1x sid..

What do you mean by stable? Do you mean a SID that runs at 125.00 BPM, in contrast to 125.3 BPM?

Some PC tools allow for 0.xx precision in BPM settings. The ones you use don't, or?

Not sure if this is a good example of the before mentioned method.
Its a last ninja remix i did 10 years ago on the PC with Fasttracker2.
It uses the original sampled sid tune chopped up to small parts and tracked along with it.

Please kindly ignore the poor mastering quality.

You can probably fine-tune the SID-samples to make them sync 100%

Yes, because i have tried this.
It is in sync for (appears to be) 1 minute.

Ok, so chopping them up, will resync.. yes...

Its just a lot of work :(

Yes :-)

I was just trying to avoid the work of chopping,
and make an automated method to get it to work..
