Hi Felipe,
Thank you very much for miniOMsynth.
but there’s something about your collective, choose “can’t close toplevel patchers” in the [standalone] inspector…
best,
Jerome
felipetovarhenao,
I tried the standalone version but I’m confused about the in- and outputs. Does it not work with midi input (fi. IAC-Driver)? I can only play with the mouse…
Hi Paul,
You need to enable OSC communication between OM and miniOMsynth, by going to OpenMusic Preferences/MIDI and make sure the default score player is set to osc-scoreplayer. Once you do that, the playback should work.
Let me know if that works.

Hi Jerome,
Thanks for trying out miniOMsynth. Why do you recommend changing that attribute in [standalone]? I did it simply to make it easier to close the app, but maybe there’s something I’m missing. Did you download the Max project to notice this?

hi,
when this box is not ticked, you can close the patch window, at this moment, you can’t see the patch again, you have to restart the standalone, it’s not very practical.
best,
Jerome
You’re right — I’ll have to change that for the next release. Thanks for the suggestion Jerome.

Hi Felipe
Thanks for your miniOMsynth which I had just downloaded. I have changed my midi OM preferences to osc-scoreplayer with the default ports. When I set a score-object also to osc-player the following OM message appears:
ERROR: cannot resolve hostname “localhost”, service 3000: unknown-host.
(I use OM 6.17 under Mojave)
Hi BUSEMARK304885,
Thank you for trying miniOMsynth and letting me know about this. I noticed this issue has come up before with other OM players (see this thread). A couple of things I’d recommend to narrow down what the problem is:
- Try updating OM to v6.18. I’m also using Mojave so this seems to be the only difference from what you specified.
- Making sure that the Force score player option is checked.
- Checking if the order in which you launch each application makes any difference in you machine.
Let me know if the problem still persists, and I’ll try to see what I can do.
Best,
FTH
Hy Felipe
- I have updated to v6.18
- The osc scoreplayer option is checked in the MIDI-preferences as well as in the score object (a voice). You suggest Force score player - is that a typing error.
- I’ve tried both launching orders: miniOMsynth-OM and OM-miniOMsynth
The problem still persists!

Hi Markus,
This is pretty strange. Just to clarify, I did mean Force score player — in OpenMusic Preferences/MIDI, right below Default score Player, you will see a checkbox that says Force score player. I suggest checking it because one of my students wasn’t getting playback until she did this. If this doesn’t seem to do anything, I will soon be releasing v1.1 of miniOMsynth which will include (with a few extra features) a MIDI input option, although, as you might imagine, is not as ideal as OSC for dynamic and accurate microtonal playback.
Just out of curiosity, how new/old is your machine?
Best,
FTH
… Yes Felipe, strange indeed. Even after checking the Force box the problem persists.
Regarding my machine: MacBook Pro (Mid 2012), 2.6 GHz Intel Core i7).
So quite old, but it works fine with Max 8 and is updated to OM 6.18.
Looking forward to try your v1.1!
Best
Markus
Hi Markus,
Sorry the issue still persists — miniOMsynth-v1.1 is now available on my github, which lets you use OM’s midi-player as well.
As you might know already, the problem with using midi-player in OM is that it’s very limited — the microtones are automatically routed through different MIDI channels (chan1 for 1/2 tones, chan2 for 1/8 tones, and chan3 for 1/4 tones) which means 1) you can’t really use channels as different instruments, and 2) 1/8 tones is the highest resolution you’ll be able to get.
There’s also some re-patching I need to do to optimize miniOMsynth for MIDI playback, but I hope it’s a workable solution for the time being.
Let me know,
FTH
Hi there!
There is one good news: if you get this error, it means that you are set up correctly in OM and your MIDI notes are now indeed routed through OSC over UDP when they are played (instead of using the MIDI player).
The bad news is that the UPD layer apparently doesn’t work and I’m not sure you can do much about it. 
The call:
(comm:get-host-entry "localhost" :fields '(:address))
should resolve “localhost” to an IP address. In your case, probably not, and therefore the connection fails with the error you reported.
ps. If this is just the translation of “localhost” that fails, you can maybe try the following:
(defun note-osc-events (pitch vel dur date chan)
(let ((evt (make-instance 'oscevent
:host "127.0.0.1" :port *osc-score-output*
:bundle (list "/om/note" pitch vel dur chan))))
(setf (offset evt) date)
(list evt)))
this redefines note-osc-events with “127.0.0.1” as hostname, which in principle is equivalent to “localhost”.
Hi Jean
Thanx for your reply. Is it maybe because Markus’ port is not opened for some restricted permission?
Just asking?
Best
k
Yes, probably not the port (it’s about resolving the host). I’m not sure what. 
Sorry yes i meant the host.
@Markus Check your network settings. Did you change your localhost to other than 127.0.0.1 ?
Hi Karim- I didn’t change anything in my localhost settings- I suppose that “Markus-Busers-MacBook-Pro-15.local” means 127.0.0.1. Sorry I am zero in network settings…
Hi Felipe,
Thank you for miniOMsynth! Seems to work flawlessly over OSC. I’m in Mojave/OM6.18. I have mid-2017 MacBook Pro.
Best wishes,
Maija
Good evening,
Thanks to the standalone version of felipetovarhenao’s miniOMSynth, I finally solved the microtonal reading for the Mac under OM7 and under windows 10 with OM17. I had tried Fluid Synth which I had seen in Mikhael Malt’s video tutorial, the interface was functional but there was no way to download the soundfonts as other users have pointed out. obviously this version was not updated for Big Sur. I tested the MiniOMSynth and if under Max 7 or 8 there are problems related to missing objects, the player works with the standalone version under Big Sur and Windows 10.
Best.
