Capture 126.96.36.199798 released on April 1, 2015 supports Sync for RM Series Mixers.
Access the downloads here: http://www.presonus.com/support/downloads/Capture
or in your my.presonus.com account if you have an RM, StudioLive AI or StudioLive mixer registered to your account.
Previous versions of Capture do not support Capture for sync with StudioLive RM mixers. Because of this, with the previous release of Capture version 188.8.131.5235 there was no way for channel names to sync or have scenes saved with the session for that would load when the Capture session is opened in Studio One.
