Hi Perry, Thanks for the suggestion, I'll try that out. In fact I realized that unfortunately killing the shred, or terminating the program is not enough to close the ports. You need to terminate ChucK. An alternative could be that of using Std.system("chuck midi_config.ck"). At this point I could simply print the port names on the terminal. Anyway, I'll try both and see.

I’m not sure if they can be closed, but as long as you don’t chuck them to now, the extra ones really shouldn’t take up (much) computational resources.  

One option would be to first run a MIDIConfig.ck file that opens them all and writes all the names and numbers into a MIDICONFIG.txt file.  Then when you run your main file, it reads that and only opens the one(s) you need.  Or your first MIDIConfig.ck file could pick the one(s) you need and write only them into the temp file.

I’ve done this for PLOrk pieces, to figure out if laptops have accelerometers, and what orientation those are.

Hi,

Is it possible to close a MIDI port?

I'm working on a MIDI class, and to print all the available ports, I open them one at the time and get the name. Then I end up with tons of open MIDI ports I'm not actually using.

Apart from this, another user case could be a live set where different scripts are launched and each of them wants to talk to a specific MIDI port. Doing so one ends up with a lot of /leftovers/.

Cheers,

Mario
