Sending Midi to Resolume Arena from Reaper: Output Sync Issue

Hi Forums,

I am using Reaper DAW (http://www.reaper.fm/) + LoopBe1 (http://ift.tt/1oEKIgP) + Resolume Arena 4 to sequence midi to control media inside of Arena.

The details of the setup:

In Reaper go to Midi devices and make sure LoopBe1 is enabled as output device (and is enabled to send time clock).
Make a new track in Reaper arm it to your midi controller, select the midi output and choose LoopBe1.

Inside Resolume, go to Properties Midi and choose LoopBe1 as the input (and leave timeclock on). Now look at the Composition mapping and map your Resolume clips to the keys you want.

What I did was set C0 to the "Record" function. And place a C0 item at the very beginning of my timeline in Reaper, then I trigger various clips along with the beat and at the end trigger C0 again to stop the recording.

When I hit play in Reaper, the clips get triggered perfectly everything hits right as it should (or so close that I don't notice).

I then take the rendered audio out of Reaper and the .mov file "Arena captured output" and go into Premiere.

What is happening:
The video STARTS in sync with the audio. But slowly overtime the video gets ahead of the audio (and it carries through this way to the end.
I've checked that each midi note triggering a clip is perfectly on the beat. (I am in piano mode anyway so it should only go to black not trigger to early). . .

I've tried using Camtasia Recorder 8 to capture the output of Resolume, but this totally kills my FPS.

Should I expect some latency when sending midi out of reaper like this? Is there anyway to compensate? I've painstakingly adjusted the video/audio in premiere but when I "get it lined up" in one part of the composition it inevitably goes out in the other.
