Acidlab who already make great Roland TR-808 (Miami) and TB-303 (Bassline) clones is recreating those products in beautiful Eurorack modular form. As far as pro-audio gearlust these things rate high on the wow I want to touch them scale. You can read an interview I did with Klaus Suessmuth here. Klaus posted these photos and information over at the Muffwiggler forum (link).
“The newest products are FRAME with 84TE space, a 5-ch Mixer and the POW-Modul. 3HE Case is at 75 Euro; the Powermodul with powersupply is at 65 Euro. POW-modules’ performance is +12V/700mA und -12V/700mA. Another new products will follow in the near future: 6HE Case, 303VCO & M303 (303-module); the 808-Drumodule will need more time. -a V/Octave to V/Hz Converter (for Korg-CV & Metasonix) will follow, too!” – Klaus Suessmuth
