It fills the bill

As a working musician whose gear is always on the go,this instrument does it for me. The Steinway emulation is pretty good,especially in the lower register. It has that distinctive Steinway "bite". The action reminds me of a vintage DX-7.(I have two.) It's the ease of transport that appeals to me;being lightweight enough to manage. I also own an M-Audio ES88 to trigger my rack-mount modules. Both of these keyboards are lighter than my DX alone. With a bit of EQ tweaking my Sono 88 sounds pretty ballsy. I like it. I would,however,like to see a hard copy user's manual. Sidebar;your customer service is superb,guys.Thank You!

Easily overlooked but highly worthy keyboard if you know what you're getting.

For a lightweight keyboard with limited (but sufficient) sounds, this M-Audio fills the bill. I used one when my Kurz SP-76 was in repair and frankly found it equally satisfying to play. It's also the only weight that makes sense for USB-ing or MIDI-ing into a desktop computer (I'm not about to drag a 60-pound behemoth to my iMac and crowded study for that purpose). The only problem is that some dealers confuse it with the "other" M-Audio ProKeys model, which has fully weighted action, twice the number of sounds, along with splits and layering, and is a totally different animal. Sweetwater's description is accurate.

I Like It!!!

This really is a nice sounding keyboard. For many years guitarists have had the luxury of inexpensive light weight instruments. This keyboard is easy on the back. The midi sounds aren't especially noteworthy but the bread and butter sounds, pianos, organ sound good. As far as the keys, you will never have two people agree on keyboard feel it is the nature of the beast. This isn't a fully weighted hammer action, but it is a very good semi-weighted action, just like many high end synths. Where this keyboard shines is recording, just connect to your USB connector and away you go. I don't use the ableton live software. I use Logic and it works great. For a song writer using a DAW or Band in a Box this keyboard is just the ticket. It also makes a very good live stage piano. Did I mention it is light? And the 2 headphones are great for giving my niece lessons without disturbing the household.
My only complaints are they should have included a power supply in the unit, I hate wall warts! And a sustain pedal should have been included. Also 7 sounds is a bit thin the prokeys 88 has 14 with some nice pads. At over $400 they should have bumped it to at least 10.
