Odd problem with Note and microtonal playback in OM 8.0

Hi Karim,
I’m having an odd problem getting microtones to play in the Note object. If I launch OM, then open a Note object, playback ignores microtones (I’m using 24 edo - and making sure it’s set within the Note object). However, if I open any other kind of Score object, it works. Once I’ve successfully played a microtone in a Chord object (for example), when I go back to the Note object, it works there too!

Any suggestions? It’s pretty easy to fix, but I’d like to be able to just play a microtone in a Note object without jumping through hoops.

Mac OS 14.8.7 (stuck there for now until I have time to deal with old Finale scores, sigh)
Thanks! And apologies if I missed an earlier mention of this issue.

Dear Per,

Yes you’re right. It seems a bug that I thought I have already fixed. I will look into tht ASAP and get back to you. And by the way it is not plateform (OS) related. So no worry about this…

Thank you for reporting this.

Dear Per,

I went through this problem, and finally it is not a bug:

The NOTE object by default has his port set to nil. The reason you don’t have microtones auto retuned while using the new fluidsynth implementation is this exact reason. In fluidsynth a port is an instance of fluidsynth. So therefore, if the port is nil, no auto microtuning is sent.
This could be corrected in the code, but not as a patch fix, because we need to implement the port for the NOTE object as a valid integer. So this will have to wait for the next release.
I suggest two possible momentary solutions:

  1. use the CHORD object instead
  2. If you need absolutely to use the NOTE object, just play a chord or another score object with the corresponding tuning. This will set the auto microtune to the desired EDO.
