I just wanted to add that even though the C.24 Miselu Bluetooth keyboard works much better with the WIDI BUD in terms of latency than the mi.1 with WIDI BUD, the velocity is pretty abrupt. It goes from quiet to loud rather too quick and abrupt. I thought it was the keyboard of the C.24 Miselu, but when I connected it to the iPad over Bluetooth, the velocity level was very smooth.
