.This is just an idea for a very ambitious z-plugin that you could considerate after some critical stuff as midifx (rerquired for this), timestretch, midi controllers, right click for erase&unselect notes (la la la la :D). It would be like to energyXT but native inside Podium.
The plugin could load the logicals MIDI Input and Audio Input (since Podium doesn’t do any difference between audio and midi) and MIDI Output (for MIDI thru purpose), Audio Output. It would load also audio and midi effects and
The innovation would be that it could also load MIDI Outputs/Inputs, Audio Outputs/inputs of other mixer tracks (this would be pretty easy for do sidechains, as other user requested).
When you would open the plugin you will see this interface, where with a simple right click you would load the plugins, and drag&drop’ing their input/outputs you connect them.
I didn’t draw this, but every audio effect would have a Dry/Wet and Balance knobs, and every synth a Vol and Pan knobs.
All the best!
edit: Example of new sidechaining (using only two tracks instead three :))
Racks in Tracktion also can be used like this. It’s a powerful feature, but i doubt Frits will find it fitting Podium’s paradigm. But i bet he could come up with something even better
