Audient’s Evo is an excellent-looking new iOS-friendly USB audio interface. Like all other “sound cards,” the Evo lets you hook up speakers, headphones, and connect microphones, guitars, and so on. It then connects to a computer or iDevice via USB, so you can route all that audio in and out of your apps.

But the Evo brings a few clever extras. One is the Smartgain feature, which automatically sets your input levels. The other is something called loopback, which lets you record your iPhone’s own output. This is handy on the Mac and Windows, but essential on iOS, and very welcome.

Roland’s new Go Livecast is a pretty fantastic little box for live-streaming with your iPhone. You can hook up microphones, use the companion app to do the streaming, and — get this — you can hook up a second iOS device and switch to its camera.

Let’s check it out.

This week we create music-synced video art with Glitch Clip, import music to our iPhone with Doppler 2, take proper control of Shortcuts with LaunchCuts, and more.

Glitch Clip is an iPad app for VJs. That is, Glitch Clip lets you combine video clips with in-app effects and visuals, and sync them to music. Thus, you can create live video performances, or you can just make killer music videos for when you put your own songs up on YouTube.

Previously this kind of power was found in apps like Isadora for the Mac, which costs over $500. And while Glitch Clip is no Isadora, it’s only 1/100th the price.

If you love making music, then you’re in the right place. If not, then next week I promise to write more about some non-music apps again — if the developers release some. Until then, we can bomb the bass, make some tunes with Tune Maker, get Unisonic with JAX, and take control of our stereo widths, all with the tap of a touch-screen.

Imagine arriving home, listening to music on your iPhone. You want to start that music playing on your home speakers instead, only you don’t want all the hassle of using Control Center, or the AirPlay panel, to do the connection manually.

If you own a HomePod, all you have to do is hold your iPhone near it, and playback will transfer. But what about regular AirPlay speakers? Can you hand off to those? Yes! You can. With a quick one-time setup, you can have the music or podcast app switch from your headphones, and play on any AirPlay speaker you have at home.

This week we boss a metronome around with only our voices, let a music app write our songs for us, and create beats and tunes like little children might. Yes, the only good new apps I’ve seen this week have all been music apps, so try to enjoy it.

Cubasis, the audio workstation app from Steinberg, just got rewritten as a brand new app. Cubasis 3 looks just like the old version, but is all-new, and includes support for the iPhone as well as the iPad. And hopefully, this rewrite also means that in the future, updates that adjust the user interface for new iOS features and screen sizes will be supported a lot faster. It took more than a year for Cubasis to support the 12.9-inch iPad Pro, for example.

So, what’s new in Cubasis 3?

Tidal today one-upped Apple Music with an even better student deal. Its 50% discount now extends to high-schoolers — not just college attendees.

Qualifying members will pay just $4.99 a month for Premium access, or $9.99 a month for the Hi-Fi plan. The discount is available to new and existing subscribers who verify their student status.

Start blasting those holiday tunes with free Amazon Music on iOS.

The streaming service can now be enjoyed without a paid subscription for the first time on iPhone and iPad, giving it a big advantage over Apple Music.

But just like other free music plans, it does come with ads … and some restrictions.
