Two models, Alpha and Pico - both quite strange      06/10/09

Eigenharp Unveiled


Yesterday was the day the Eigenharp roadshow kicked off in London at the BBC's Maida Vale studios. After 6 weeks or more of teaser videos on YouTube and scant facts we can now reveal the nature of the beast.

Heralded as the "Most revolutionary musical instrument of the last 60 years" it's quite a claim.  Specifications published in the Eiegenharp website reveal that there are to be two instruments the flagship Alpha (£3950) - bristling with controls and features, and the smaller and more affordable Pico (£395).

Essentially the system comprises of the main instrument unit, linked to a base station via a 6m lead, which in turn links up to the computer (Ma only) via USB.

  • Up to 750mW output on a 3.5mm mini jack.

Microphone input/preamp:

  • Balanced input on an industry standard 4 pin LEMO locking connector.
  • 24 bit at 96khz A/D converter.
  • Low noise programmable gain from 10 to 55db in 1db steps.
  • Software switchable 48V phantom power.
  • 8.2V Electret polarisation power available, requires specific cable.

  • 26dB software switchable input pad.

Base Station:

  • 2 inputs for continuous control expression pedals:
  • Suitable for use with Boss FV50 and FV500 volume pedals.
  • Suitable for use with Yamaha FC3 continuous control sprung sustain pedals.
  • USB 2 interface to host computer.

Quoted:

You can load and play your own Soundfonts, Audio Unit Plugins and Midi instruments with the Eigenharp Alpha. In addition, the Alpha comes with its own native instruments (at present a software model of a Cello, Clarinet and a Synth engine). The Alpha also ships with a collection of loop libraries and several acclaimed instruments from our partners:

  • 1500 AIFF format (timestretch and tempo change capable) varied Percussion and Drum loops.
  • Sampletekk 'Black Grand Steinway D, sampled at 20+ levels in a 6 Gigabyte set that includes three recordings from dry to highly ambient.
  • Sampletekk 'Tubed Rhodes', a multi sampled Rhodes Electric Piano.
  • Sampletekk 'Wurlittzer' electric piano in a Gigabyte multi sample set.
The software is Mac Only.
Meanwhile, the Pico offers:
  • 18 playing keys.
  • Sensitive to direct pressure and to lateral pressure in both directions.

Breath pipe:

  • Sampled at 2000 samples/second.
  • 12 bit (4098 value) resolution.
  • Sensitive to blown and drawn breath.
  • Removable, interchangeable mouthpiece for easy hygiene.

Strip Controller:

  • 180mm long.
  • Sampled at 2000 samples/second.
  • 10 bit (1024 values) resolution.
No word on availability just yet, but pricing is as one would expect for a revolutionary instrument that has had eight years of development put into it.
Eigenharp Alpha £3,950
Eigenharp Pico £395
