The rmx will work right out of the bow.. no problem with that.
You should think about if you can really use the RMX..
On the demo's it looks awesome... But is it ?
If i had the chance to test it properly before buying , I wouldn't bought the rmx
The effects on the scene FX are: Echo , HPF echo , Lpf echo , Crush echo , Bpf echo, Spiral up , Spiral down , Reverb up , reverb down , noise
So if you do not like the echo effect, then the rmx isn't something for you :)
Also the remaining effects on the Isolate fx aren't that usefull ... I already have an isolater on my mixer (djm 2000)
The same is for the gate / trans / roll leaving me with only the Cut / add / drive effects
This is MY little feedback for the RMX , many users are very happy about the rmx.
So the conclusion is : Test it properly before you are spending your money
