4Pockets’ MultiTrack Recorder Plugin is an audio-recording app that can be loaded inside other music apps. If you’ve ever seen an app like GarageBand or Logic in action, you’ll be familiar with the layout of multiple tracks on a horizontal timeline. MultiTrack Recorder Plugin offers exactly that, only it’s designed to be used inside other music apps. Apps that don’t have their own recording functions.

Instead of just firing up that ambient music playlists again today, why not try the PolyPhase app? It’s a “generative sequencer,” which is an accurate but uninteresting way of describing its purpose: to create great music, automatically.

PolyPhase is intended to be used as a creative tool. A music can manipulate its settings, and listen until she hears something worth saving and turning into a song. But the app is equally good as an ambient soundtrack generator. One that will never stop. Ever.

Audiobus, the iOS app that lets you route audio between apps on your iPad or iPhone, just got an update. The version number is 3.0.5, which belies the fact that Audiobus 3 just got one huge new feature: support for Ableton Link, which means that it will now keep tempo with all the other music apps on your iDevice.

If you want to make music on iPhone or iPad, you can choose from an embarrassment of fantastic iOS apps. You’ll also find plenty of music effects and recording apps on the platform.

The problem is using two types of apps together, because iOS isn’t nearly as flexible as macOS when it comes to digging into the system. But with a $10 app called Audiobus 3, you can route audio between apps. That means you can send music from, say, a drum machine to an audio recorder, or from your guitar to a sampler.

Further, you can route audio from many apps at a time, letting you create as complex or simple a setup as you like. If you think of Audiobus as a set of virtual patch cables for your iPhone or iPad, you’re on the right track.
