"This is the most advanced Theremin ever created. The original circuitry has been greatly enhanced in every way known. It has been fitted with every possible refinement and feature. It goes FAR BEYOND any other instrument and is truly suitable for the connoisseur player. This is the Stradivarius of Theremins, incorporating all of the Parenteau Mods, and much much more.

As you know, Clara Rockmore became the ultimate virtuoso of the instrument, provided for her by Lev Theremin after a car accident took her concert violinist abilities. She stunned national audiences with performances with national symphony orchestras and her other-worldly stance while playing. While it was certainly theatrical, it was also necessary as the instrument is sensitive to even the slightest movement of limbs or body. It takes precision finger control to truly play this instrument. In photo above, we pay homage to Clara and Tev.

The PAIA Theramax is an electronic Theremin kit that offers several substantial improvements and increased versatility over any other Theremin that has ever existed. Nonetheless, various virtuosi have made many modifications and refinements in its design. THIS ULTIMATE THEREMIN incorporates all of those refinements, and then some.

For starters, while the VOICE of this instrument is variable from smooth to aggressive with the TIMBRE control, the original design lacked the individualistic "warmth" of the antique RCA Theremins that established the instrument as a viable addition to a symphony orchestra and as stunning accompaniment to voice. Here, the engineer with over 40 years experience designing and constructing Theremins, has added, via a switch, the choice between the CLASSIC RCA of yesteryear, and the more modern timbre range as heard on recordings in the past few decades.

Another addition: CUE OUTPUT JACK for use with headphones to properly determine pitch, prior to final output.

The adjacent switch allows this jack to also be used as an AUXILIARY INPUT that bypasses the internal voice, allowing you to replace it with the sound of anything you input.

OTHER FEATURES:
Control Voltage Outputs proportional to Volume and Pitch for control of any CV - based electronic instrument. Yes, it is possible to control MIDI signals from CV signals. If you're into that, you're welcome to inquire.

There are also EASY ACCESS FINE TRIMS on VOLUME and PITCH.

An attenuator on the CV voltage output and a jack for a MUTE footswitch (optional).

The VELOCITY SENSING aspect of this Theremin is unique. A CV (control voltage) proportional to HOW FAST YOU MOVE is available. This can be used in external signal processing for even more sensitive nuances on the final sound.

But we didn't stop there: Note the central switch. It allows conventional Voltage-Follows-Velocity or a Fixed Output, until your Velocity Changes!"
