Roland A-49 White

Well, let me start by saying that this is a beautiful keyboard. In my opinion, it looks among others in its price range.

And the build quality is quite good. I compared it to numerous competitors that all turned out be inferior (some keyboards feel excessively plastic, or the keys produced an unpleasant mechanical squeaky sound of the springs inside). None of the sort with this one.

First, I thought it could not be used (powered) without a computer. A year or so later I found the way to power it up from a USB power supply (a feature not documented in the user manual). For those who want to know, you have to press and hold Pitch+Assign keys before you plug in the USB cable (some sources suggest pressing Function+Assign+Pitch, but I saw no difference).

All in all, I'm quite satisfied with the product after I found the way to use it in the the stand-alone (w/o PC) mode.
