The Alpha from Eigenharp is a professional-level instrument that allows a musician to play and improvise using a limitless range of sounds with virtuosic skill. It excels as a performance instrument, delivering endless permutations for control and expression of either the supplied instrument sounds, or of virtual instruments from other manufacturers.
The instrument consists of a unique control "surface" containing a total of 133 highly sensitive keys that are internally sampled at 2,000 samples per second to deliver incredibly detailed control nuances. The sampling is also applied to the two strip controllers and the breath controller, providing almost endless possibilities for flexible keyboard layouts, fast instrument switching, and expressive musical control.
The Alpha, when connected to a required Mac computer, 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. Additionally for the solo performer, it can control an entire set. A very comprehensive built-in sequencer works for both percussion sounds and pitched instruments.
A feature rich software system provides a wealth of musical performance features that includes the already mentioned playback of the instrument's own native sounds, along with many common software plug-ins, Soundfonts, or external MIDI instruments via the MIDI outputs available on the included base station. The entire system has been built to withstand the rigors of live performance, and since all sound generation takes place on the computer, the controller will never become obsolete.
