This is a list designed to be searchable an findable!
of Perfect bpms. ie bpms without a remainder (374.8318)
(it was mainly just a self reference but here you go!~)
according to renoise all of these bpm’s have 0 decimal pionts. 32.0000
(i see the possibility that it could go deeper than 4 places so use at your own risk!)

You should probably also mention that these need to be at speed 06 or 03. It’s still possible for “125 bpm” to be inaccurate if you use speed 04, 07, 08, etc.
interesting.
but this got fixed in the next version, right?
AFAIK yes.
The configurable bpm timing has been made leading but only when certain speed settings are used, this is however ofcourse a far better solution than the current <=1.52 implementation.
Ha! Dblue, you got me. i overlooked this, i’m pretty sure i was using speed 6, i probably should have made a table instead.
anyone know how to change topic titles? i havent been able to figure out how to do this on really any board that im on!
off the top of anyones head, is it possible to use tables on here? (invision forum stuff)
theres another forum i use that has a plethra of options like syntax scrolling & coloring an tables an stuff, but i dont know if any of that would work on this one.
As long as you are moderator or admin, you can do this.
With any other regular user state you can’t.
So i made the topic title more fitting to the actual related content as there is no such thing as perfect bpm in Renoise (or any other host for that matter).
If you desired another topic title, i can copy and paste, but it can’t have much more amount of characters than it has now.
i tested your bpm’s.
amd64 x2; renoise version 1.52 at speed 6:
50 bpm
75 bpm
125 bpm
150 bpm
250 bpm
375 bpm
the rest is off, here.
so different cpu’s, different “real” bpm’s ?
Looks interesting… i feel the Intel bug-cpu coming around the corner again, but the list was made by a Mac owner (don’t know if the table is based upon Intel or Apple’s native cpu).
Either that or AMD is now the one, having some sort of bug, there is definately a difference between AMD and Intel, not only in performance.
On my AMD X2 4800+ the following bpms appear to be “accurate”. Which is to say that there are 4 zero’s after the bpm, ie. “150.0000”. I suppose it’s possible that some of these are also inaccurate but we just can’t tell, ie. “150.0000037”.

I noticed some interesting anomalies when you get up into the very high bpms. Sometimes two neighbouring bpms will appear to share the same “real” bpm, ie. 344 and 345 both display as “344.5313”, 354 and 355 both display as “354.5016”, etc. This occurs with increasing frequency the higher you go, and eventually you get to a point where 3 bpms are the same, ie. 489, 490 and 491 all display as “490.0000”.
For the record I also quickly checked things out on my Intel Centrino laptop, but I didn’t notice any difference between the CPUs as far as which bpms were accurate or not. Both CPUs seemed to give the same results.
PS. This was all done on Windows.
.
oh whoops, i should have mentioned i dont really use renoise on mac anymore, those were done on a windows pc, w/ an amd athlon thoroughbread as the cpu.
this hole is getting Deeper! xD
i had no idea this is related to cpu’s!
i guess i should do this same thing on my g4 ibook an my thinkpad.
then i guess we could have more comparison to work with.
ppc,pentium & amd
g4 ibook (ppc)

wow…
405 & 406 = 405.3309
408 & 409 = 408.3333
411, 412 = 411.3806
414, 415 = 414.4737
417, 418 = 417.6136
420, 412 = 420.8015
422, 423 = 422.4138
there is too many of these.
489, 490, 491 all equal 490.0000
man, renoise is Nowhere close to precision i had originally thought it had. i cant wait for the next version!
heh, this is certainly a waste of time, but at least i have a list now to look at for myself!
