A professional level instrument which allows the musician to play and improvise using a limitless range of sounds with virtuoso skill. The unique design of the keys makes this the most expressive electronic musical instrument ever made. The Alpha can play and record loops, change scale and key, transpose, alter tempo, program beats, create arrangements, switch and layer multiple sounds, all while the musician is performing live on stage.
Available in a variety of finishes, it has 120 highly sensitive keys, 12 percussion keys, 2 strip controllers, a breath pipe and numerous pedal inputs. This gives almost endless possibilities for flexible keyboard layouts, fast instrument switching and expressive musical control. The comprehensive software system provides a wealth of musical performance features, including playback of its own native instruments, many common software plugins, soundfonts or midi instruments.
The Alpha requires a Mac computer to run. Click here for full software specification.
