OK.

My initial impressions were....WOW!!

An extremely flexible piece of kit that allows me to use two machines and still have room for Ableton channels.

The effects pad is great and can be assigned in a variety of ways that offer flexibility and playability.

However, it is a bit noisy on the outputs with a definite hiss that seems excessive for a mixer of this calibre. I am investigating further. I know of one other user who also noticed the hiss/noise and finds it unacceptable.

I have yet to investigate the midi functionality but it seems straight forward and flexible.

I'll report back some more info later.
