We're not entirely sure if the Seaboard Block M is really the "new dimension of music creation" that ROLI claims it is, but it does have new dimensions compared to the Mk1 version, so perhaps that's what the London-based firm means.

Seaboard Block M is an update of the original Seaboard Block, a more mobile version of the company's Seaboard RISE MPE keyboard that followed the release of the original Grand model a decade ago. This introduced the concept of the 'five dimensions of touch, and these are still in play in the new Seaboard Block M.

A quick recap: the five dimensions are enabled by the special 'keywave' playing surface of the Seaboard. Strike is the first - the more traditional playing of the keys with velocity. Press is the equivalent of aftertouch so comes into action after you Strike.

The more unusual ones are Glide and Slide, which can send MIDI information as you move your fingers left-right (Glide) or slide them up and down the keys (Slide). Finally, Lift sends information depending on how quickly you release a key.
