The E300 is a collaboration between Dave Rossum of Emu/Rossum Electronics and Synthesis Technology to bring the legendary MOTM-300 Ultra VCO into Euro format. The E300 adds a switchable sub-octave output, has more stable and accurate tuning, and uses standard parts (no tempcos or other exotic stuff).
The sound qualities of the original MOTM-300 are preserved, using identical audio paths.
The improvements are in the CV paths, where modern op amps and a new exponential generator are used to keep the E300 rock-solid for days of use.
Size is 14HP, 30mm depth.
