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.
Mozaic: Latch and Switch v1.6 - MIDI latching / routing and note display (mainly) for arpeggiators
I have just released this wee Mozaic script.
I created this script because my KeyStep MIDI controller does not have a proper latch/hold function, and I wanted to use various software Arpeggiators in the same way as the one in my Roland SH-01A synthesizer:
This synth allows you to play monophonic melodies without the arpeggiator already turning your notes into a staccato. Only when you press more than one key at the same time, the arpeggiator starts working.
And this is what the AUTO mode in this script is for. With the advantage, that you can even allow for more than one note to be active before notes are sent to the connected arpeggiator.
On top of that: Of course latching, note display, and several ways to mute notes including a fully fledged MIDI panic.
