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.
 
If you want to control different engines with the same controller, there are two ways:
- you can setup the different engines so that they only receive a certain MIDI channel, and then you just have to choose the channel on your controller. This implies that you can change the channel on your controller quickly and easily,
- you can use any midi filtering tool (mididings is a really fine one, that I woul recommend, but you also can do it with qmidiroute or whatever) and create a patch (or route or filter) that will route the MIDI signal to the engines in a way that would be controlled by a knob or a button on your controller. You can check an example with mididings here: https://github.com/PlagiatBros/PlagiatSetup/blob/master/Controls/Mididings/cmeKeyboard.py (you can omit the zyntrebleGMandela thing and the gateCancel): basically, the mididings patch routes the MIDI signal to a different pair of Output/Channel for each Scene, and the SceneSwitch is controlled by ProgramChange.
 
Hope this helps.
 
(btw Plagiat is a band, born on the ashes of Sebkha-Chott, running a live setup using synths, loopers, samplers, mixer, FX, routing, monitoring, lights management and VJ-ing using Debian GNU/Linux and free softwares only, as Sebkha-Chott did before)
