    It appears this keyboard-module came with a 3000 series Eurorack module. with a 15V psu-connector, a 7 pin din socket for the keyboard and 4 bananaplug cv in/outputs. Anyone got any info/pics concerning this unit?

    1. That keyboard does feature the awesome two piece bender, up and down in a fraction of a heartbeat, or at any particular rate. Neat as it is, the very special thing to me appears to be the staccato button feature. I believe this removes a cap or diode that limits or eliminates bounce from the keyboard contacts (wild conjecture based on a very old memory of an explanation) and the response from the non velocity keyboard suddenly changes. It offers a very spitty opportunity if the keys are applied conscientiously. I suppose you would have to experience it to believe, but I think it is tremendous and unique.
