It's just to bang around on when I'm traveling. I want to have full-width keys.
What I like about the Roland Go Piano is it doesn't waste any space on the sides of the keys, so it's almost the same width as the MX-49 but it has 61 keys.
More keys, AC/DC, I give the edge to the Roland for travel, but the MX49 has all of those great EPs, organs, and synth sounds. Does it have stuff that I would want to use at home that my PSR-S970 doesn't have?
Larry thanx for adding more detailed info...if I'd known that I wouldn't have offered the info,.....have fun in your travels.. and whatever you choose...that said the Roland GO Piano is a good sounding choice.
