On Qranger you can create unlimited BUS Midi Outs ports.
Each BUS midi OUT port can be connected where you like on the all available Midi Inputs: asio, Gigasampler, Rom..
On qranger tracks preference you can assing each midi tracks to the desidered BUS midi OUT and the desidered midi channels.
Same also for the audio tracks, you can create unlimited audio tracks and routing to the esidered outputs.
Qranger MASTER audio out include the elastique pitch shift, so the all audio tracks routed to this out port will be transposed when you change the chords pitch.
All the tracks routed under Drums mode, mean that wil never transposed.
here a shoot:


For the other feature that you have request, we use the Performance burn system.
It mean that you setup the all pannel how you like and the OS will burn one image setup of the whole configuration.
Note: all the multiple asio Host used on the performance must be running, the performance system will NOT launch the windows application but only setup the sounds/program change.
