The fgdp-30 is fantastic. Pads has a great feel and sensitivity, 3 finger playing is a brilliant idea from Yamaha.
It acts very good as midi controller. I use it with Addictive drums in general midi mode. The only thing i must do is to remap the pads, all the others are ok.
It is also very good as audio card. You can record via usb the internal sound.
The internal speaker is very nice for practice.
When you change values(volume, drum kits) you listen a female voice to tell you about the changes(very clever way to replace the luck of a screen).
The sound is excellent and more than 30 drum kits to play.
When we will play more i will tell you about the other functions!
