The E950 Circuit Bent VCO is a unique VCO module from Synthesis Technology. Using licensed technology from the original Texas Instruments LPC speech synthesizers (such as the Speak and Spell), the E950 contains original voice ROMs and algorithms from two generations of speech DSPs. Additionally, 2 banks of 16 wavetables each from the E350 Morphing Terrarium are included for a low-cost morphing VCO.

The E950 can speak in both "normal" and "circuit bent" modes, all under voltage control. Unlike traditional circuit bent toys and keyboards, the E950 is very repeatable and controllable, adding deep new timbres to your modular synth.
