It’s not surprising a lot of Studio One users also have Ableton Live, because they’re quite different. I’ve always felt Studio One is a pro recording studio (with a helluva backline) disguised as software, while Ableton is a live performance instrument disguised as software.
Fortunately, if you like working simultaneously with Live’s loops and scenes and Studio One’s rich feature set, Studio One can host Live as a ReWire client. Even better, ATOM SQ can provide full native integration with Ableton Live when it’s ReWired as a client—once you know how to set up the MIDI ins and outs for both programs.
Now ATOM SQ will act as an integrated controller with Ableton Live while it’s ReWired into Studio One. Cool, eh?
To return control to Studio One, reverse the process—in Live, set Control Surface to None, and toggle the MIDI Ports that relate to ATOM SQ from On to Off. In Studio One’s Options > External Devices, For ATOM SQ, reconnect ATOM SQ to Receive From and Send To.
Note that with ATOM SQ controlling Studio One, the Transport function still controls both Live and Studio One. Also, if Live has the focus, any QWERTY keyboard assignments for triggering Clips and Scenes remain valid. So even while using ATOM SQ in the native mode for Studio One, you can still trigger different Clip and Scenes in Live. If you switch the focus back to Studio One, then any QWERTY keyboard shortcuts will trigger their assigned Studio One shortcuts.
Note: When switching back and forth between Live and Studio One, and enabling/disabling Studio One and Ableton Live modes for ATOM SQ, to return to Live you may need to “refresh” Live’s Preferences settings. Choose None for the Control Surface and then re-select ATOM SQ. Next, turn the various MIDI Port options off and on again.
