Reply to Looking at acquiring an RMX1000 but have a few questions for use in Abelton

Hey all,
I'm interested in adding an RMX1000 but not entirely sure if it will work well with my setup.
I'm using two CDJ2000 and a Xonedb4. As many may know the Xone does not natively Send/Return so I'm looking at using the RMX as an EFX unit in Abelton during my sets. So my signal path is CDJ to mixer via digital, mixer to Abelton via USB, Abelton back to mixer. My concern is whether or not the RMX can internally determine BPM while running as a VST in Abelton or if I'll have to manually adjust Abelton's tempo via MIDI. If I have to manually set tempo would I have sync/phase issues with the audio signal from the CDJs? I'm hoping it would just be a generic tempo that the VST/RMX would "react" to when an effect in engaged and not reliant upon a 4/4 count inside Abelton--meaning that although the tempo is correct, an effect would be out of phase with the original audio signal.

Hope this makes sense. I tried posting in the Pioneer community s a few days ago but my post still hasn't been approved yet...for wtv reason.

Thanks
