E300 Ultra VCO Ready for Pre-Order and Available Nov. 15th, 2019



E300 Ultra VCO

E300 Ultra VCO Available Nov. 15th, 2019

The E300 Ulta VCO is based on the 5U MOTM-300 VCO with improved enhancements and added features. Introduced in 2000, the MOTM-300 was based on a sawtooth core designed by Dave Rossum and used in the EMu modular.

The E300 still uses precision, low drift resistors, adding improved C0G ceramic timing caps, the latest in low drift and low THD OPA op-amps, and a new, unique triangle waveshaper that generates ‘glitchless’ triangles and sine waves.

The MOTM-300 was very sensitive to the rise time of external VCOs used to sync, and the E300 uses a much-improved sync/triggering scheme to allow any signal, with fast or slow edges, to reliably force the sync.


The E300 will also be available in black at no additional charge. Synthesis Technology targets to ship in early November to Synthesis Technology dealers.

About Synthesis Technology

Synthesis Technology was founded in 1998 with the introduction of the MOTM modular synth format. This format enabled musicians and electronics enthusiasts to build their very own DIY synthesizer, one module at a time. Although the 5U size, 1/4″ jack connections, and utilitarian black front panels recalled the Moog modular synths of the 1970s, the MOTM format improved on the modular synth concept with updated components and engineering techniques. As microcontroller technology leaped forward in the early 2000s, the all-analog MOTM lineup was augmented with digital modules such as the MOTM-650 polyphonic MIDI interface.

Poly-8 Voltage-Controlled Oscillator (VCO)



Poly 8 Voltage Controlled Oscillator VCO

Poly-8 VCO

Wavefonix launched their latest eurorack module the Poly-8 VCO. This new eurorack module is now available to order from the online store. Poly-8 Voltage-Controlled Oscillator (VCO) represents the first in a line of 8-voice polyphonic modules developed by Wavefonix that will be released in the coming months.

The Poly-8 VCO module is one of a kind. It is a premium polyphonic oscillator bank, comprising eight CEM3340 (Rev. G) VCOs in a clean, compact and ergonomic design. Each VCO features a vast range of modulation capabilities, including hard sync, PWM, 1V/octave and exponential/linear FM.

Each VCO provides simultaneous ramp, triangle and pulse waveform outputs. The authentic CEM3340 architecture offers an instantly recognisable, rich analog sound found in many famous synthesizers from the past, such as the Prophet 5 etc.

  • Premium polyphonic oscillator bank comprising eight CEM3340 (Rev. G) VCOs.
  • Three simultaneous, buffered 10Vpp (±5V) waveforms per VCO, including DC-coupled ramp, triangle and pulse outputs, with controllable PW and PWM CV inputs (0V to 10V). Pulse output is derived from the CEM3340’s triangle waveform using external circuitry.
  • Individual coarse and fine frequency control knobs provide an adjustable frequency range of more than ten octaves (approximately 8Hz to 16KHz) for each VCO.
  • Each VCO has a wide range of modulation inputs; including hard sync (comparator-based), PWM, 1V/octave and exponential/linear FM (switchable).
  • Ergonomic design.
  • Hand-built and tested in the UK.
