Sound Bank: not bad and rich of option, free combination allowed and good sample quality, easy to set up via the Main Module or USB.
Main Module: nice build unit, too much of a plastic feeling and knobs and tuner are too small if you have big hands, nothing that bother me tho. 2 x extra output available, not all main module offer that at this price range.
Rack: the rack is nicely shaped and it is made of solid material, upside is that it doesn't transfer much vibration to the pads, down side is the winged screw system to build the rack together. they are ok but after few hours of practicing you need to tide them up over again. can be solved by replacing them with standard screw and bolt system.
Pads: i have tried out Roland and Yamaha pads from much more expansive drum set and honestly these from Millenium are really good mesh, nice look, nice feeling and the bouncing of the sticks is really realistic. the anchor point provided to connect the pads to the rack are a bit weak, needs to be adjusted every few drumming sessions. Hit stick noise is pretty low.
Cymbal: 3 x 3 zone cymbal with choke.... no need to add more. really nice to play on and not to noisy when hit with sticks.
Hi-Hat: this is the only item i will replace soon, the response and the open close function is not the best around, will probably changing with the Alesis Pro X Hi-Hat set which I had before on my Alesis DM6 and was very happy with it.
Kick Pad: solid and silent, even with double kick set-up, had to add a screw in the back so it doesn't run away from me while playing.
Easy to configure from main module or from PC via USB.
cable provide are of good quality, maybe 50 cm extra on each of them would make the wiring and cable management easier.
Overall impression is good, really good and so far I'm enjoying it really much. For this price i do not think you can get anything better that this one.
