Notable features:

o MIDI input, but not out!
o Audio out mono
o Section "keys" but not tactile Management velocity
o Storage of 8 sequences: too light, especially without export
o No power sector provided! (Batteries included but it's something)
o The global hash functions or pattern ("share") of good quality
o The rest has already been widely said again :-)

UTILIZATION

Super subjective opinion, but probably consensual:

The use is top, very intuitive interface, and a few "hidden" features fully explained in the manual that extend a few more features (for example: press <Func> + <Power> start to change global settings).

SOUNDS

I was not sure what to expect:

o Excellent sound overall, slap in the ears!
o The bass drum is great, especially with the decay!
o The snare is not so successful as that, I think, contrary to other opinions
o PCM sounds are really well chosen and playing with the PCM Speed knob, it gets cool sounds!
o No panoramic

OVERALL OPINION

The Q / P is really excellent, definitely.
Remains to be seen as part of the offer because demands Volca Beats in his studio. I think the use companions to create rhythmic slightly anywhere / anytime, other than with an MPC-like.

PROS:
o Super nice to work with
o Sons PCM
o Sounds pro, it is not in the gadget
o tactile keys that I feared are excellent
o Effects hash well rendered

CONS:
o lack of memory slots and the inability to export
o not velocity sensitive (but volumes of shares remain adjustable)
o No AC adapter ...
