It's good. Considering if you buy a piece of hardware like this it will cost you around 400$+.
Found few videos on you tube

Personally I'm loving it. Apps like this make me love my ipad even more=)
There are so MANY great music apps on the ipad it's unbelievable. Last night I bought minySynth pro and miniDrum pro and I'm having a blast with this two.
You can make your beats on miniDrum then import them directly to miniSynth pro and record you synth melody on top of the beat. Amazing.
Is the sound quality studio like? No it will never be able to compete with daw's like cubase , logic etc....But it's pretty damn close , don't forget you can also sample your own sounds on it=)
I just HOPE that Korg will turn ims 20 into a midi controller.
Also keep in mind this is the 1st gen ipad and look already what apps we have to our disposal.
Immagine what they will be able to do with a more powerfull ipad.
