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- Plasmonic synth for desktop
By the creator of Absynth. Just released. It sounds great and has a wonderful MPE implementation.
It’s 99$/EUR right now.
Plasmonic combines the resonant depth of physical modeling with subtractive synthesis. Our goal is for Plasmonic to approach the depth and detail of an acoustic instrument, while making it easy to shape the sound into anything you want. Its deep modulation capability and MPE support make it very playable and expressive.
