At first, sorry for bad English. I know its Linux forum and I using Windows but maybe solution of my problem can be equal for both OS.
What I actually trying to do that I want to send my Traktor decks into Ableton separately for returning effects to mixer channels. I don't know much about Jack2 and MIDI messages but I want to try to figure out what's what. I tried to make Jack2 works with my setup but unsuccesfully.
My setup: MSI laptop with Ryzen 5 5625U, Windows 10 22H2;
Ableton ver is 11.2.6, Traktor is 3.8.0;
Traktor A10 interface: 2 main inputs and outputs set to be used for send/return FX's (PSP42 delay plugin and Ableton reverb), all remaining outputs goes for Traktor decks;
DJM 800 mixer: 3 Traktor decks + 1 Ableton for drums and 2 mono mic returns for FX's (2 RCA to 2 TS jacks), also using MIDI cable connected from DJM midi out to midi in of A10 and mixer turns into MIDI controller;
Xone K2 MIDI controller (ch15, all layers) which I setup with controlling 50/50 Traktor and Ableton using 2 applications: loopMIDI and MIDI-OX;
Launchpad S MIDI controller with LP95 script;
And one more thing is - DIY adapter (6,3 female stereo jack to usb) with arduino pro micro onboard working with M-Audio expression pedal that allows to control delay's feedback;
Two programs synced by Ableton Link function.
The problem is that Jack crashes and loopMIDI mutes channels. When I start sending MIDI signals from any MIDI device its instantly crashes Jack and makes loopMIDI mute his virtual ports
When even a midi cable is connected from the card to the mixer, the jack does not start
I looked in Jack's patchbay and tried to create connections in MIDI client but i don't understand how. Maybe certain client launch options is needed, or another 3rd party app to implement this, maybe I'm wrong. Please help!
