| Summary | 0010156: Launchkey Mini MK4 DAW integration only works with new sessions | ||||
| Description | I recently acquired a Launchkey Mini 37 MK4 after using the Launchpad Pro for a while. The DAW integration doesn't seem to work with my existing Ardour sessions that I've tried so far. Holding "Shift" on the launchkey the "DAW" pad among others doesn't light up. The Launchkey is detected and checked in the Control Surfaces settings, though. I checked for differences in the settings between sessions and saw none in mini connections, etc. For some reason after some use this behavior impacted new sessions as well until I wiped my ~/.config/ardour9 directory. It seems that if I use the Launchpad Pro, it still works fine in all cases. | ||||
| Steps To Reproduce | 1. Load an existing Ardour session (that was previously used with Launchpad Pro). 2. Plug in Launchkey. | ||||

When I switch the Audio System to ALSA, save, and reload the session, then the DAW integration works. Not sure why it's different for launchpad vs launchkey. |
|
|
Using ALSA for the audio system in Ardour does funky think with sound for the rest of my system outside of Ardour. It's odd that using Pipewire/Jack for the audio system works fine in a new session, DAW integration and everything. |
|
|
There are bugs in the Pipewire JACK MIDI implementation that make is unusable for control surface support at this time (not just the Launchkey). |
|
|
Dang. I'd been using it since I started using ardour a couple years ago. |
|
|
Any program that's using ALSA directly blocks access from every other program trying to play sounds, so the funkiness is as designed. That's one of the reasons things like JACK were created; to be able to multiplex audio sources. |
