"Current modified circuit bent speak n read by bentstruments"


via this auction

"Here we have a Benstruments, circuit bent Texas Instruments Speak & Read.

Just like the Speak and Spell, exact same voice only the Speak and Read has better beat looping in my opinion.

You also have a small vocabulary of words you can type in and the speak & read will say the word typed.

Works as a normal Speak & Read until you flip a glitch switch.

Ive added these new controls:

Opto-Theremin Pitch Control with on/off switch

LFO control with rate led and knob, shape knob and pitch depth knob.

Tone oscillator button that creates a tone you can then manipulate with the pitch controls like a theremin

1/4" output jack that shuts off the onboard speaker when you plug into an amp or pa system

Loop switch with on/off and advance button for cool beat loops

Reset switch to get it back to normal

Glitch forever switch that sets the speak into constant gibbering of incoherent sentences

Dual voice glitch switch that causes it to speak in both a high pitch and low pitch at the same time

Ive added all the coolest mods you can find on these sweet robotic bent synthesizers. I guarantee all of my bentstruments for as long as you own, my work is solid and ive modified hundreds of toys and synths that are employed the world over by both famous and amateur musicians. Great piece to bring some creativity to your work."
