the sound depends what you use it with, but the quality of sound is nearing perfect. It responds intensely quick to my playing, very expressive. I can be fluent in many types of music with this tool and the exciting thing is I can use this as a live midi trigger or for just about any instrument or drum vst I have. Finally a keyboard without a mandatory dc adapter - usb rules! - I love Edirols!

I only wish It shipped with the expression and sustain pedals... I don't have extra cash to use for those, and I would really like to try them out.

The Quality of the keyboard seems pretty excellent other than it does not have wieghted keys, I have had similar feeling keyboards with keys that would break too easily, this is the only worry I have, I am a bit aprehensive at taking it touring or anything.

Very worth the price, I bought it as soon as I could afford it!

I don't know how the company's support system is, I have never had to use it. I guess that is a good thing.

This is really a good looking keyboard, I love the amazing power indicator. It's space-age! Edirol has come a long way! Also a very practical necessity for a small studio.

My music style is electronic folk, emo, indie, etc.

There is not sound, it's a midi controller, not a synth keyboard. I use it with softsynths, sequencers, hardware samplers and a G5. So, I'll just rate how fast it sends info into the sequencer, without error, here.

The controller has tons of options, and memory sets. The pitch/vibrato well are good, and feel nice to work with. Edirol's PCR Editor software, from there website, make assigning custom pan/fader/utils changes easy. Can use midi, midi-thru, and usb interfaces. The display (vertic send) that displays midi info sent, etc, is quite helpful, and if set correctly, will tell you exact values of moving faders and pans, based on those of your software (Reason, etc). This does not mean that they are moving/automatable faders, just to be clear. It simply means that it display number/midi data in relevance to you software.

It's made of plastic, but it's far from a paper weight. I wouldn't take in on the road, but it's good for in-house. The color and build is appealing, and the pan pots/faders/buttons all function as they're supposed to.

It's worth what I paid for it, but there are better, just not in this range. Most other controller in this range, that I've tried, are level are below, in comparison.

Haven't had to contact them.
