REQ: Wavesfactory Marxophone (updated 2016)
Doesn't look like there's any kind of trial, unfortunately.
The sound of the Marxophone is reminiscent of the various types of hammered dulcimer in music traditions world-wide. It has four sets of chord strings to be strummed with the left hand and two octaves of double melody strings, which are struck by metal hammers activated by the right hand.
