ConVertor E1

Pitch tracking, expandable oscillator alongside a studio preamp.

The ConVertor E1 merges the pro-studio into the Eurorack modular synth into what can be called the ultimate “synth channel”. With its pitch tracking DCO alongside a preamp with many pro features for the instrumentalists and vocalist, or for the working musician professional/sound engineer/designer. All functions in the ConVertor E1 are digitally controlled and can be saved/recalled as presets for a plug n’ play, intuitive performance while leaving you with analog CV outs to continue your sonic journey. With MIDI 2.0 ready digital interfacing option, firmware and hardware expansion, and polyphonic options, the ConVertor E1 is an extremely versatile tool.

Currently receiving pre-orders, limited production run. Shipping late March 2021.

Product description:

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 VCA, attenuvertor, analog compressor, CV compressor/expander, quantizer, VCO mode, auto-gain, and multiple expansion options both in software and hardware. 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" is optional. With a 3rd generation technology, the ConVertor E1 is capable of detecting the pitch of the audio and synthesize a choice of four waveforms (presets) as well as extracting the pitch, envelope, and gate CV signals as accurately as ever before. Built for efficiency and stability. The intuitive interface shows best when performing functions of what would have taken additional 7-12 external modules. It offers saved/recalled from presets for a "plug and play" live performance/during expensive studio sessions where time is of the essence. With digital output MIDI and sustain pedal expansion options via the MIDVertor E1 module (sold separately). * = With expansion module the MIDVertor E1

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 +50db 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 and attenuator/attenuverter. There are also separate ENV CV compressor/expanders and attenuverter/attenuater to each internal CV destination like the VCA and CV out. The FM input also has its own quantizer, and attenuverter. 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 out. In VCO mode the oscillator will be controlled only from incoming 1V/oct CV input.

Download below the 2-page User Guide that shows you exactly the functions and how to use each one in the ConVertor E1. The ConVertor E1 can play either true-sine, triangle, square or sawtooth waves and output from the 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. The FM CV input can accept external CV sources to shift the pitch the oscillator as well but can do so continuously or quantized to musical scales. With internal VCA, VCF, quantizer, attenuverters, LFO's, routing and different modes of operation, the ConVertor E1 offers presets to keep the show going smoothly.
