Using presonus studio one for live backing track, click track , and lighting via automation lanes (dmxis, or EMU) or a midi track. Presonus could easily surpass other apps in this use if it would simply add an "input monitoring follows selection option". We can use midi controller buttons to call a macro which finds and selects a particular track. Say goodbye to mainstage. we can setup synths and full channel effects for those synths and simply push a button on our midi controller and select a particuar synth (track) and monitor enable it without touching the computer. Keyboard players would ditch mainstage in a heartbeat if they are already using studio one and are familiar with it.
