well, because I am working nearly 70 hours a week... and I do not have the time for this... I already have a hardsid with 4 sid´s... but while I am working all day in front of my computer I am not interested in switching this machine on at home... this is the reason why I would like to have it as hardware. and it seems that the possibilities of this synthz are much more than using a sidstation. cheerz diet
