Heya everyone,
this is slightly more complicated idea, so unless you have some experience with computer game engines or 3D creation softwares, this may seem very confusing,
feature I would love to see in Sonar is visual routing of inputs/outputs, effects, patches, instruments and all the other stuff, all neatly organized in some kind of graph,
for a reference, see this image example of "Blueprint" in Unreal Engine 4:
now just replace blue frames with tracks, and the parameter inputs with actual inputs, parameters, effects and so on,
maybe even whole modules indicating Mix Recall adjustments or sequencing/looping with let's say custom (midi)key command inputs would be convenient...
I am not expecting to see this feature in Sonar anytime soon, but IF it was ever implemented, I'm pretty sure it could bring Sonar to whole new level!
