ConVertor E1

Pitch tracking, expandable oscillator alongside a studio preamp.

Translating the natural nuances of an audio signal to analog and digital synthesizers, accurately, in an ultra-compact but expandable module. Developed from the ground up, the ConVertor E1 packs an enormous amount of features compared to its size. With a professional preamp, internal VCO, VCA, LFO, analog compressor, ENV CV compressor/expander, quantizer, DCO, auto-gain, and multiple expansion options both in software and hardware.

Product description:

With a 3rd generation technology, the ConVertor E1 is capable of detecting the pitch of the audio and synthesize a choice of waveforms (presets) as well as extracting the pitch CV, envelope CV, and gate CV signals as accurately as possible today. Built for efficiency and stability. The intuitive interface makes controlling its plentiful functions easy. Functions that would have taken additional 7-12 external modules are now offered at a touch of a button. It offers saved/recalled memory of all settings so you can power it off, turn it back on and carry on where you left off. An expansion MIDVerotr E1 can add MIDI output sustain pedal input, arpeggiator to MIDI and back to ConVertors, centralized control for groups of ConVertors and more all via a high-speed, bi-directional 4-pin header connection we call the "Sonicsmith bus".

The ConVertor E1’s preamp audio input can receive a balanced/unbalanced audio signal at line level, instrument level, or dynamic microphones with a clean preamp featuring a unique auto-gain of +54db range to accommodate all types of audio sources. Pitch tracking evolved to become so accurate that no filter is needed, no matter the source material or its frequency range. The ENV now has a compressor / expander. The FM input also has its own quantizer. 6 Character LED meter reflects the input level of the audio input or menu choices periodically. VCO mode will separate the preamp from the oscillator leaving it completely independent while still providing the ENV CV and pitch CV outs. In VCO mode the oscillator will be controlled only from incoming 1V/oct CV input, either continuous or quantized.

Download below, the 2-page User Guide that shows you the functions and how to use the ConVertor E1. The ConVertor E1 can play either true-sine, triangle, square, sawtooth, PWM or a saw-square-mix waves from its SYNTH output. The P-SHIFT knob is an inf. encoder that shifts the relative pitch of the internal oscillator and the pitch CV output within a 5-octave range in semi-tones. Encoder can also be pushed to go back to unison quickly. With internal VCA, VCF, quantizer, compressor/expander, attenuator, LFO's, routing, and different modes of operation, the ConVertor E1 offers memory of all settings to keep the show going smoothly.
