Pretty Decent New Controller
I just got it and I imagine I'd deviate from the 3 star rating based on how this thing lasts over the next few years, but initially, it is really good. I was wondering what they truly meant by semi-weighted keys as there's a million things it could mean.... what is the pressure like, does it give the feeling of bounce and balance that you get between the key and hammer on the real thing, etc. The keys still feel like keyboard keys, hitting them and touching them, you still get the tactile sensation of the hollow keyboard key. The weighted feeling is replicated by pressure/resistance to pushing or striking the key. In no way does it feel like a real piano key, but it also doesn't have the light pressure touch of a standard keyboard key. Even with the extra pressure, the keys lean towards keyboard more than piano. So don't get your hopes up way too high, but it's still better than nothing!
Otherwise this thing is simple, kind of a bubbly plastic retro looking not very flashy case that would still look somewhat dated sitting in a music store in 2002. Simple input controls, powered off the USB bus that you might use to sync midi with your computer, or if you choose to use the pinned midi ports then you need to pick up a separate power unit for it. If you plan on using this with a MacBook Pro and already have 1 of the 2 USB ports dedicated to an audio interface, and you need to keep a USB port free, then don't forget to get a separate power pack for this thing. (9VDC 500mA). Of course that's assuming you have the audio interface to hook the pinned midi cable through.
Not a whole lot else to say about it! If you need a decent built simple controller to simply play the sounds on another device, this works perfectly.
