I wanted a compact mixer for a portable synth setup for live sets, and it's perfect for that.
Being USB-powered is one of its best assets but also what will make your setup more tricky, as it's really easy to get a ground loop due to USB power and unbalanced 3.5mm jack inputs.
But other than that, it's a bless! Easy to use and great sound, the reverb/delay are awesome and the master compressor perfect for live situations.
I did not use the recorder much, it does the job but it's a bit bare at the moment as there no transport and overdub possibilities.
The 1010 can also act as a USB host for a controller if you want hands-on access to all parameters, but it won't passthrough the MIDI from USB to its MIDI ports, which is a bummer (but maybe fixed in a later update?).
Overall, there's no other digital mixers as compact, portable and full featured as this one, and 6 stereo/12 mono (assignable as you need) is huge for such a small format!
