BPM 2 Detune {cents}
« on: July 16, 2008, 19:05:38 »

Hello everybody,

here is a gnumeric spreadsheet that calculates the cents needed to detune a drumloop to fit a specific tempo in BPM.
Hope this is of any use, I havent red all the forum and dont know about the various (windows) utilities out there.

No way to view that file, but does that deal with actual, real world BPM, or tracker timing? What happens if/when MilkyTracker is adjusted to better match the original FT2 speed? Also, FT2 finetuning ignores the 3 least significant bits..

Gnumeric is a spreadsheed app like excel and available for linux, windows and as source code. http://www.gnome.org/projects/gnumeric/

I use it like this:
- you got an unknown loop...
- you make a test track with length 1 bar
- you start playback and alter the song tempo and sample fine tune to match one bar of the loop. You now know the original tempo given as #note, #temp and #speed.
- after that you can use the loop in your arrangement, calculating any #note and #finetune values to match your song tempo. A value of 403,78 eg. means four halftones up + 3,78 cents (sample finetune of aprx. +4).

Does that answer your question?

Edit: if speed is set to 6 and basenote set to C-4 the file will play at 'real world timing', IMHO. But I might be wrong on that one.

Tip: If that was an excel sheet (or export from openoffice), you can also load this into Google Documents and use it in your browser.

As it is, I don't think many will install that Gnumeric software just for this :) Still, thanks for sharing.
