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 beautiful ebony and silver finish, it has 120 highly sensitive keys, 12 percussion keys, 2 strip controllers and an optional breath pipe. 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 or a Windows computer to run.

mikemilton's review"A wonderful experience to play"

Eigenlabs Eigenharp Alpha
If anything was 'perfect' this instrument would have got my vote.

I've had an Alpha since they first became available. While they are able to act as a MIDI controller, they are really a complete instrument by themselves, have several 'internal' sounds and can host virtually any AU or VST.

The Alpha is exquisitely made and is, as a result, expensive. (The Tau is essentially the same and very reasonably priced)

What do I like?
- it is incredibly tactile and expressive, well beyond what MIDI is capable of
- there is total configurability
- one can load multiple AUs/VSTs at the same time and play them simultaneously or sequentially in multiple keygroups
- It has an excellect mic-pre and headphone amp built in
- all information (including mic and in-ear monitors) flows through a single cable (mine is 80Ft long) giving complete freedom of movement
- The ability to configure the instrument and SW has greatly improved and continues to be refreshed

Knowing what I know now:
- if I were buying one now, my only wish would be to have bought earlier at a better price

Is there a not-to-like
- it has quite a learning curve and the keys are *so* expressive they take practice (like playing a fretless instrument)
- You can play any hard or soft synth right out-of-the-box using factory setups but advanced customization
and making your own setups can be technically challenging (this has improved greatly)
