Hello,

when I use Jack2 on macOS, how can I get realtime prio 95? I only get 10, no matter what I am trying.

This is my command /usr/local/bin/jackd -X coremidi -d coreaudio

JACK server starting in realtime mode with priority 10


Qjackctl doesn’t allow me to set a new value.

All the best, Daniel

Hi there,

My few takes on this

Linux (ALSA) applications can create a virtual midi ports either with
jack or ALSA

On windows this is not possible (*)

The only reson loopMIDI can be seend is that LoopMIDI is a Windows MIDI
device driver, so it can be seen by windows a a MIDI device  and thus
also by  Jack.

VMPK is a client, it connects to TO  a Windows MIDI  port (not sure it
supports jack) 

Pd could only connect to jack if it supported to create a jack client
port, suppose it' can't

Here is discord for MIDI , you could also try to post on midi.org forum
or on linuxmuscians.com
Not sure if there are any other forums for MIDI, targeting non-Linux.
https://discord.gg/bkdNqbF3

(*) until Windows MIDI 2.0  comes out, and then,  no idea if jack will
support the new Window service as the new service is similar to jack
Windows MIDI 2.0 will support legacy MIDI 1.0, so perhaps  then it may
support connecting ports to each other and also Pd to jack through that
new service.
I haven't looked at this scenario yet. 

Besides that , perhaps we will see something alike pipewire on windows
which already has replaced the jack driver on Linux.

Thanks

Probably a long shot because most of y’all are on Linux, but I’m on
Windows and trying to use Jack2 on Windows to connect MIDI applications
and failing horribly.

In QJackCtl the option to select a MIDI driver is just greyed out? I’ve
been able to use loopMIDI for a loopback MIDI device to connect
programs, but that sidesteps Jack completely which is not what I want.

In my testing scenario, I have Pure Data (Pd) running the audio/midi
test patch, and Virtual MIDI Piano Keyboard (VMPK) as well, a piano
keyboard. I can use loopMIDI to connect the two and Pd will
successfully send random MIDI notes to VMPK which it will then play as
audio. But again, I want to be using Jack for this instead so I can
manage things in one place.

How can I route MIDI data between these two applications via Jack on
Windows?
