Casio SA-5 Vactrol Paradox Circuit Bend

[uzi4u182]

thats crazy. i have that exact same keyboard, except in its original toyish form!

You've done a fantastic job with the control surface... very professional and solid looking. And it sounds every bit as good as it looks. AWESOME WORK! 10/10

unstoppably bananas, but what is a vactrol and how does it work? is it some kind of photo-sensitive related thing?

[vomiol]

A vactrol is a photoresistor, which changes resistance based on light, wrapped up in electrical tape or glue with an LED, which lights up in response to voltage. so you can wire the led to respond to some part of the circuit, in this case i think it's just lighting up with the sound output, and then wire to two ends of the photoresistor to anything else you want to control. it could be the pitch, for example, so that when you play a note on one thing it makes the pitch spike. hope that helped.

I love this thing. I think i saw it at ad noizium but i never got to hear it. Just been down the shed freezing to death with an sa8. Watching your vid yesterday made me think of trying out the vactrol idea with a pot on the overdrive. worked a treat :) Stuck a simple fuzz in there too and it sounded even better. Then i buggered it up somehow and sent the keyboard mappping wrong. Oops, that'll teach me to go poking around those pins that i KNOW are bad news :D

really cool work.

[alexdatsko]

killer. sounds alot like my concertmate380 but i only have the glitch bible aleatron bend nothing fancy.. i also have some of those voice changer chips ht8950 and the datasheet to build the stock applications, nice work combining some really glitchable gearz =] would you be interested in sharing any of the good bends in the ht8950 schematic?

[WhistleFork]

I like this a lot!

Is the voice changer a separate circuit you are housing in the keyboard?

Also, how did you hook up the vactrol's LED to the signal? Wouldn't an LED that big just completely drain it?

This sounds amazing, keep it up!

At the begining I was getting bored and about to leave but than it got realy good and even better and better. Great bends!
