OK, finally figured out what's going on here. The not only affects RB...but every other DAW I use: Cakewalk and Reaper.

I'm using a Helicon Voicelive 3 to drive harmonies from a MIDI track in my DAW's. I've set one of the outputs on the DAW to the VoiceLive 3 and directed the harmony track to the Voicelive. No problems, harmony track is going to the Voicelive and I can see the Natural Play light confirming that MIDI is being received. Vocals are perfect.

Here's where it gets weird. I also have a software Voicelive Editor from the guy over in England. I also use his Editors on two other Helicon units: Voicelive Touch and Perfrom VK...no issues with these. These Editors are absolutely indispensable for navigating the many layers in the VoiceLive 3. If I try to open the Editor while the song is stopped in Realband, the Editor refuses to open. If I shut down Realband, I can immediately open the Editor and it will establish full functions in the VoiceLive.

On the other hand, if I start up the Editor and its controlling the Voicelive and then start Realband and add the Voicelive as an output, I get the error message that there's not enough memory to run the Voicelive. Seriously?...with 32 gig of memory!

It seems that the Editor completely takes control of the Voicelive and will not let any other device share it.

I've look at running by midi only, running by USB only, look into Win exclusive mode. I've even stripped down my system such that only my computer, RB, my audio interface (Focurite 8i6) and the Voicelive are running.

Can't make heads or tails of this. Have never seen a software completely take over a piece of hardware and exclude any other use of it. Don't think it's a DAW issue as it happens in all 3 of my DAW's. Can't be a Win Exclusive issue as that's turned off for everything I can turn it off on.

Anybody got any ideas about this? The developer over in England seems willing to work with me on this problem but we can't figure out what the problem is.
