I just noticed on the MICRO that you assign so many different sounds 139 to the 4 PAD buttons almost like the multi-pads on Yamaha units...this can be very useful, Jingle bells etc...plus you can assign many functions to the pads also..eg: drum mute, page down/up, fx mute , etc..

PADS (1–4, STOP)
These programmable pads can be used to trigger a
sound effect. Use the STOP button to stop a cyclic
sound. Each Pad corresponds to a dedicated Pad track.
