Mine just arrived and I'm sort of impressed.
Good points:
The keyboard is perfectly playable. It's not a piano, and not a synth, but a nice mix of the two. 88 keys is good.
Nice package - lightweight, feels solid
Controls easy to spot, and display legible
Internal speakers better than I expected!
Given the few dedicated controls, UI is easier to use than I thought it would be.
It's a very nice MIDI controller for soft-synths (though I haven't worked very hard on that).
And the bad:
The audio out through USB is terrible. It starts breaking up at about the 8 o'clock position on the volume. It actually starts feeding back at high volumes. Maybe it's the way I have it set up, (Aggregate audio device with a TASCAM audio interface) but I feel it's basically unusable. Comes in at 48kHz, 24-bit, so it should be fine. Playing back analogue to the -10dBu inputs on the TASCAM works well a bit faint on the +4dBV front inputs. Ignore this - it was a CKI problem (CKI = chair-keyboard interface = me)
The Stick 2 is weird. It seems to be programmed as a pitch bend X direction on a lot of the presets as well as other things in the Y direction, and seems to have no X auto-centering!! Stick 1 doesn't seem to work that much. Again, I haven't been through all the presets.
Oh, and the figure-of-8 AC adaptor cable came with a Euro-plug, rather than a UK version.
Basically, it's a nice piece of gear, with the reservations above. Pianos sound pretty OK through better speakers, organ (I'm not an expert) sounds are usable, and the synth and other presets are pleasant enough and editable. Sliders/drawbars are fun. Definitely good enough for me. The other issues (USB sound out, stick assignment, etc.) are all issues that can be solved with firmware upgrades - don't know if this is something Soundlogic is known for.
