It fits into the trunk and stays there during the gig, I bought a used one for just 85 euros. Even works on batteries.

(EDIT: Warning: This one is discontinued, but the newer A-49 only works with a computer attached - VERY stupid.)


When I got a Roland A-49 a few years back, I, too, thought it was stupid the A-49 could not power up as a standalone. I found a trick on the internet.

How do I power up my Roland A49 MIDI controller with a USB power supply (without a computer)?

Hold the Function, Assign, and Pitch buttons while plugging the unit in to the power supply to enable the controller to receive power in standalone. Once you’ve done this, each subsequent boot should work normally with the power adapter without having to press that combination of buttons. [/quote]

That works? Funny... A normal USB power adapter apparantly doesn't work.
It's bizarre as I read the A-49 needs some kind of driver to work, either from PC or at least via iPad, but then that's obviously wrong...
