Roland offers a solution to spur-of the-moment sessions where inspiration can come from anywhere. Zentracker, the music pioneer, has released a free app for Android and iOS. It can be used as a multitrack recorder to create spontaneous performances. The app allows you to add unlimited tracks (it defaults at four), create 200 audio loops, and use 16 audio effects. You can also use familiar features such as beat matching and looping.
You can save tracks to OneDrive and Google Drive are "coming soon". You can use the app for free as long you have a Roland account. However, Roland will encourage you to subscribe to Cloud by restricting certain effects, loop bundles, and stem exports to paying customers. To make the most Zentracker, you'll need a mixer such as the Go: Mixer ProX.
An app is available for formal productions. Roland will release the TR-Editor desktop application (below), which acts as a companion to TR-6S/TR-8S machines. From your computer's screen, you can browse sounds and program beats as well as adjust parameters. We are still waiting for details on the launch of the software, but it could prove useful if the TR-series' interface on your device is too complicated.
