"these are rare keyboards. this one was sent in on commision. casio va-10 is a keyboard and a multi-effects processor which can effect sounds onboard or from external ins. an ambitious keyboard for the consumer market that didn't make it far for production.
this keyboard had alot of bends that were unstable so i just went for a simpler approach to effect the effects processor.. the kinds of control you can apply to the effects proccessor range from feedback depth, unique ring modulations, continously variable bit depth reduction, clocking the pitch shifters like a whammy, psychadelic panning effects, strange sounding chorus sounds, modulating pitch for sampling and delay playbacks, etc etc.. some of the multi effects onboard controls aren't very useful but when bent some in particular are very effective.
on this keyboard besides various ways to control the effects i've added an onboard sample looper that is sent from a seperate output from the main outputs on the keyboard.
in this demonstration the self oscillation from the delay feedback from the effects is used as it's own as an instrument.. there are various ways to EQ the delay feedback, vary it's modulation and depth, and it can be pitched just like an analog delay feedback..
that plug is a power cord 9V negative tip. the sound you hear is coming from the speakers on the instrument in this demonstration
it's a really great piece of casio gear.. when bent it probally is one of the more unique effects processors out there.. good luck if you ever find one.. this one has to be sent off unfortunately.."
