I stumbled across this on USTREAM:
It's the entire original announcement presentation of the KORG m01 from a month ago. This is also floating around on youtube, but the USTREAM stream also has demo performances by Simonger Mobile, koishistyle and keishi yonao. all extremely entertaining =)
Interesting thing though, something that the performances demonstrated was a slightly different implementation of live playing in Song Mode. There's a "lock" feature that, when turned on, allows you to choose the next pattern for the song to play, from once the current pattern has finished playing. That way you can have multiple "passages" laid out throughout your song view, and all you have to do is launch the one you want by selecting its first pattern in time. That should make playing live a lot less stressful =)
If i'm not mistaken, this is how Ableton Live does it as well.
