Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Solved Monitor AUv3 input to color(?), a bit like the Roadmap item Busses as destinations
(EDIT: Thanks @espiegel123 , solved. Gear icon on AUv3 instrument window title, set monitor through particular color, ostensibly achieves a colors-as-busses-as-destinations without requiring donuts or clips to be recorded, with main outputs off for those instruments. Marvelous).
It was mentioned over on https://roadmap.loopypro.com/feature-requests/p/busses-as-destination-and-multiple-destinations-for-busses that "it is possible to monitor at least inputs through color channels."
But I don't see that functionality in the way I had hoped it meant I could monitor AUv3 instruments routed to a color and not need them to go to the main outputs, and apply grouped processing and sends.
so I assume Marcus is referring there to turning on the monitoring of a "physical" input,
as opposed to being able to turn on monitoring inputs to(on) a color channel and therefore you could treat a color as a group buss without having recorded a clip or donut as yet.
If this is so, (IE no don't be silly, bruques, you can't turn on monitoring of a color and hear whatever is routed in to it, through it), is it that that the use case of grouping of AUv3 instruments on a channel is only going to be available once this Busses as Destinations feature is complete and in a release version?
May I please enquire @Michael if there is any tentative timeline for such?
I'm working around it, and am not stumped, but I'm nevertheless really looking forward to being able to group inputs not just donuts, as and when this is available.
