ROLI has announced it is now shipping the Seaboard RISE 49, a four-octave version of its expressive Seaboard RISE MIDI controller.

Pliable, pressure-sensitive keywaves take the place of keys on a traditional keyboard. The sensor-embedded keywave surface lets you shape sound through touch. Three faders let you fine-tune the responsiveness of the surface to touch.

The RISE offers what ROLI calls ‘5D touch’ – you can get different types of expression by:

• striking the keywaves
• pressing into them
• gliding sideways along them
• sliding up and down the keywaves, and
• lifting off.

Here’s the official video intro:

The Seaboard RISE 49 is available for US $1,199.
