I bought the Keylab Essential 49 last week and there are a few caveats.
While is DOES have a real MIDI port and can be powered either by USB or Wall Wart the controls are kind of stupid. You CANNOT use the encoder wheel or increment and decrement buttons to scroll thru patches on a hardware module.
Apparently those controls can only be used with their own VST software.
What I can do is set up the 8 drum pads into 6 banks of 8 individual patches that I have to program manually one by one. So I can basically program 48 patches as my setup.
This has been confirmed by their tech support.
On the other hand, the keys are very light and have a decent feel comparable to a Korg X50 or mid range Casio WK model. If you are familiar with those boards and like the key feel you would not be disappointed.
Currently I am still debating with myself as to whether I'll keep it or else send it back to the store in exchange for something else.
I think I am leaning toward keeping it.
In practice I rarely use more than a dozen patches anyway.
