I too am very frustrated with the lack of a librarian only version of VC. I work in DP7, so in order to access all the VC features I have to stop working, plug the USB lead in to my laptop, make any changes or access patches, unplug the USB and continue. No recall within the song apart from midi patch information which I have to update in Cherrypicker EVERY TIME I go through this process.
Come on Access: It's a great synth, and I'm sure there's a good reason why it's not supported in DP, but give us a librarian, PLEASE!!!
