[LAU] Live setup question with Carla

Hey hey, I am helping a friend to set up a live performance system. The general requirements are: one master keyboard connected to a notebook, which hosts several plugins (VST through wine and Pianoteq in some form). The challenge: switch the sound engine which the master keyboard is controlling via MIDI (from the keyboard) or through another cheap controller. The current state: use Carla to host the instruments and try to map certain MIDI controllers to switch the internal routing. To that end I found one thread on Linux Musicians, where FalkTX suggested using some MIDI filtering plugin (like pizmidi-plugins or x42) or a standalone app like mididings. No final solution was posted/described. Does anyone have a working solution to that kind of setup? It doesn't necessarily have to use Carla at the core, as long as it can host the instruments involved. Namely, these would be vb3 version 2 and M-Tron Pro (VSTs through wine) and Pianoteq, in which ever format. As far as I am aware, no layering or splitting setups are intended. Best wishes and thanks for any hints, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * GitHub: https://github.com/jeanette-c * Twitter: https://twitter.com/jeanette_c_s Do you even know what I like Just what I'm living for, What I adore <3 (Britney Spears)
