Check if JACK is 32 or 64 bit?

Post by CurtainsOpen »

Hi!

Does anybody know of a way to check if your JACK installation is 32 or 64 bit on Linux -> Ubuntu (I'm using Pop_OS!)? I installed JACK using
sudo apt-get install jackd
Context: I've run into a problem where Musescore can't detect my MIDI keyboard, so someone suggested using JACK. But JACK can't find my Musescore application, so someone suggested that JACK might be running 32 bit whilst Musescore version 3.+ is running 64 bit.

I am completely new to JACK and relatively new to Linux and Musescore, so there might be something obvious that I've overlooked. Thanks in advance for any help!

I don't believe a 64-bit app can even use a 32-bit lib.

Anyway, be aware that there are 2 versions of jack (jack1 and jack2). They handle midi differently (and stupidly). It may or may not be related to your problem.

Linux audio/midi is such a tragic mess, that I take a "nuclear approach" to fixing it.

I would run Synaptic, and mark the following items for "complete removal":

Jack
PulseAudio
Pipewire
MUsESCORE

Execute that. Then mark MuseScore for installation. It will install whatever else it needs.

Warning: This could potentionally mess up audio in other apps. But it likely will fix your musescore problem.
