The inspiration for a song can surface whether or not your full studio is available, and Roland has a solution for those spur-of-the-moment sessions. The music pioneer has introduced a free Zentracker app for Android and iOS that serves as a multitrack recorder for impromptu performances. You can add unlimited tracks (it defaults to four in the name of simplicity), draw on 200 audio loops and wield 16 audio effects while using familiar features like beat matching and looping.
You can save tracks to OneDrive, and Google Drive is "coming soon." The app is free as long as you have a Roland account, although Roland nudges you toward a Cloud subscription by limiting some effects, loop bundles, stem exports and other features to paying customers. You'll likely want a mixer like the Go: Mixer Pro-X to make the most of Zentracker, too.
There's an app for more formal productions. Roland is releasing a TR-Editor desktop app (below) that serves as a companion for machines like the TR-6S and TR-8S. You can browse sounds, program beats and tweak parameters from the comfort of your computer screen. While we're waiting on launch details as we write this, the software could be handy if you find the TR-series' on-device interface too cumbersome.
