Musynx (2015)

MUSYNX on Switch starts from a library of over 90 songs, with free updates adding more once downloaded. Four- and six-key layouts, adjustable note speed and key sounds make it a useful collection to learn rather than merely sample. Pop, trance, rock and chiptune styles help break up longer sessions. Its presentation and song browsing are plainer than the larger licensed showcases, but you can work through the included music without a rotating subscription.
