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.
ROLI hardware is disposable garbage when the batteries die
I have two Roli Control blocks, that cost over $160 plus tax.
The batteries are dead, and Roli responded that they're garbage now:
Thanks for getting in touch!
I'm sorry to hear your Blocks are not charging. Since you purchased the Blocks used they have no warranty, so we wouldn't be able to replace. We don't sell individual components for Blocks so I'm afraid that you wouldn't be able to replace the battery either. I recommend getting in touch with the original seller and returning or exchanging your Control Blocks. Please let me know if you have any additional questions or concerns and I'd be happy to assist you.
