Synthesis Technology E300 Ultra VCO (Silver)

Analog oscillator based on the MOTM-300

The Synthesis Technology E300 Ultra VCO is an analog oscillator based on the MOTM-300 5U module, with an updated design engineered in collaboration with Dave Rossum of Rossum Electro-Music.

The E300 uses modern temperature-controlled exponential converters without the expensive MAT-02EH + Tempco found in the MOTM-300. It also incorporates variable HFT (High Frequency Tracking) for a wider, more accurate 1V/Oct input. The SYNC circuit is a simpler hard sync type, with accurate detection of any waveshape/frequency used. There is an added -1OCT/-2OCT sub-octave squarewave output, which is phase-aligned with the sawtooth.

The VCO core is a new sawtooth-based circuit with improved linearity and a unique saw-to-triangle converter with no glitch in the transition peaks.

Just like the MOTM-300, the E300 is designed to be the best tracking analog VCO available (over 10 octaves) with the lowest temperature drift (typically less than 0.1Hz over a 24hr period).
