I have the MPD16 and I gotta says its very useful if you want to bang on them pads. Make sure you get an ASIO driver because latency can be very annoying with the MPD. I suggest you get the new version which is the MPD24.
nah dont delete the current drivers.. just install the asio drivers and then when youre in FL go to audio settings and select the ASIO driver instead of your soundcard
