Filtering micro-tones

Hi there,

Is there a way to separate micro-tones from a chord-seq or a voice ? That’s in order to get all micro-notes on one side for the instruments able to play them and all semi-tones on the other side for instruments which can’t play micro-tones.

filtre-micro of the OM-Tristan Library removes the micro-tones, but only for chords…

Thanks a lot for your help !

Hi,

Yes it is quite easy to do.
First, you’ll have to set an approximation value whatever: 1/4, 1/6, 1/8, 1/16…
For human players the most feasible is probably 1/4 tones.
Then you build a filter patch of the kind below(see attached file).

It is not programmed to filter micro tones but when you’ll understand how it works you can easily add this criterion.

Have a good day.

Thanks JM for your answer !

I’m quite new to OpenMusic so I need time to study this but it actually looks like what I’m looking for !

Best regards !!

Alright it now works !

I attached the solution i found (i guess it’s one at least).

Thanks for your help JM, I learned a lot with your patch !

Best regards !

Thx Paddys ! It’s a good example of the use of once-mode !!
