And it seems that it also fixed the crashing problem. :)
Seems that if you change uzi 15 to uzi 8 (rows, under NEW button) fixes the out-of-range problem.
Thanks for the marvelous device. There seems to be a bug in it. It crashes my machine within 5 minutes of use. When I open the device, it reports on Max console that 'matrixctrl: cell coordinate(s) out of range'. I don't know whether the odd breaking behavior follows from this, but I thought you would like to know. Otherwise it's a fantastique device. Keep up with the good work! :)

Shortly: It defines the upper limit to how close the next step is to the last step.
