Please accept my apologies if this post is in the wrong forum but rightly or wrongly, I deemed that it was the most adequate.
I am the lucky owner of a Nektar Panorama P6 Midi controller keyboard and Bitwig but lately they have stopped "dialoging" together.
The P6 is deeply integrated with Bitwig and both have been faultlessly working together on Manjaro since I installed it for the first time back in October. The duo has been thru many Manjaro updates since and have been very reliable up until I did an update around the 27/03/20 after which they stopped working together. I was hoping that future updates would solve the problems - well... not so but there is hope!
My configuration: Laptop: MSI GT 72 2QE Dominator Pro OS: Linux Manjaro (latest) Kernel: 5.6.7-1 Manjaro KDE Plasma: 5.18.4 DAW: Bitwig 3.1.3 (for Linux) P6 Controller script: Bitwig_Panorama_Linux_2019-08.zip P6 Firmware: v01.14.03
The P6 is detected by Bitwig and appears in Bitwig's "Controller settings" panel (see picture below) but the controller's piano keys, sliders, pots or pads stay unresponsive with the midi event light in Bitwig not flashing.
Now, to eliminate the possibility that the P6 could be damaged, I tested it successfully with standalone synths outside Bitwig (i.e standalone VSTs via Wine and/or VST, Lv2 etc... via Carla patch-bay bridge.
After many unsuccessful tests with my installation and research on the web, I stumbled upon a thread on the KVR Bitwig forum relating to a similar problem but for an "AKAI Mini controller"
In one of the posts, the KVRist @sth pinpointed that "pipewire" could be the culprit and suggested to disable it by typing in a console:
$ systemctl --user stop pipewire.socket $ systemctl --user stop pipewire.service
which I did and... Hooray!! it worked!
Based on @sth comments, the way I understand it (please don't hesitate to correct me if wrong as I am willing to learn) is that pipewire, automatically preempt all available MIDI devices (I guess before Bitwig has a chance to do so) which is a real nono for Bitwig's direct/exclusive access requirement to communicate with the Controller Scripts!
Well, I don't really have one right now... I only wanted to pass on @sth's tip to the community so other users, who like me use Bitwig's deeply integrated midi controllers under Manjaro, have a quick and easy workaround!
I also wanted to highlight the problem to the Manjaro team in case it is something of interest/importance for the future of their fantastic distro.
Last but not least, I would like to thank KVRist @sth for his perspicacity and finding without forgetting the Manjaro team and this community for their dedication and hard work to keep us safely on the bleeding edge of computing!
