Cubase map? As soon as mine comes in I plan on making one if I can't find one. I hate not having a map.
I'm happy with the nano key so if the nano pad is anything like the nano key then I say go for it. Someone did a comparison of the bigger korg and said the pads even though they were smaller felt better on the nano than they did on the bigger korg pad controller (no idea what the fuck the damn name of it is and to lazy to google).
Actually Toontrack has maps. Log in and go to downloads then scroll to the bottom where it says extra downloads, click superior, and then host stuff, then select your daw and maps.
nanoPad comes with mapping and editing software for the device. I do all the mapping within the DAW but it is possible to do it with the software included. nanoPad is cool but just don't play too hard as the sensors are pretty sensitive.
