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.
OT: Blue light filter (physical or night shift replacement) that "works" for older iPads?
I use night shift on the iPad pro at about 75% which helps a lot late at night. Pretty jarring though when I add the old iPad 4 to the mix and the blue light is so harsh in comparison. Things I've tried to fix this:
Sideloading an old F.lux - started asking for a developer account (seems it only works with 99 yearly developer account, the free account no longer works)
Sideloading Goodnight - same thing about developer account
Jailbroke it with H3lix just for flux. Semi-untethered jailbreak and the h3lix app sometimes won't open to unjailbreak again from iPad. I'm not always around laptop for this.
☝️ any current way to do this and keep it working for more than days via sideload/jailbreak? Old ways seem to not work.
Figured I'd just put a physical blue light blocker on there so it's less hassle. Look at selections on Amazon and most look clear (mainly glare guards) and some say, "for ladies" and "9 hour sleep" marketing rubbish. Asked questions and the replies were to the effect that they don't block much blue light despite what the possibly fake reviews say. Does anyone have a suggestion for a physical filter that works blocking blue light on iPad 4? Even contemplated putting a camera gel sheet with binder clips holding it on it, but that's not gonna work.
