Hi, Florian,
 When I light it up, buttons 2 and 7 light up... I don't know if this is the latest version, but this warning on the kiwi manual kind of scares me:
 "WARNING - If this procedure fails the 3P will be rendered unusable and will require a replacement CPU from KiwiTechnics. Use at your own risk."
 Also, on their page
http://kiwitechnics.com/updates.htm
 it says that i should provide a serial number. Any idea where can i find this, since I bought it with it already installed?
 As for the arpeggiator, I'm pretty sure I'm doing something to cancel it, but I don't know what. If I activate it (by presssing tape and then hold) I get no sound from it. If i then press hold again, it acts like a normal hold, only that no chords will play, single notes only. But if i then start pressing some chord multiple times, it acts like an arpeggiator -going through all the notes i have in that chord, one by one, at the speed that i'm pushing the notes. Only with hold on, otherwise no sound.
 I'm pretty confused about a lot of things for the moment (for example if i have both midi in and out connected, it starts doing stuff on its own, not responding to anything i do), so any advices on how should i handle it (i have mapped most of its paramteres on a midi controller) are more than welcome - i don't know problems you had and handled..
 Thank you,
 Costin
