‘The Pioneer’ Modular Synthesizer

The Pioneer features redesigned primary Emu modules that, whilst following the original style, are electronically new. It is also planned to produce additional modules to add to existing systems or as part of a new one. (Note that these modules will be completely compatible with existing Emu modular systems)

The currently available ‘Pioneer’ modules are:

  • EA2002 Dual Voltage Controlled Amplifier
  • EA2011 Quad Voltage Controlled Amplifier
  • EA2101 Voltage Controlled Low Pass Filter
  • EA2140 Voltage Controlled Multimode Filter (12dB Lowpass, Bandpass, Highpass, Notch)
  • EA2201 Voltage Controlled Oscillator
  • EA2211 Multi Waveform Voltage Controlled Oscillator
  • EA2215 Triple Range Switch
  • EA2351 Dual Delayed Transient Generator
  • EA2352 Dual Transient Generator
  • EA2411 Lag Processor
  • EA2421 Pot Pourri – (Dual Low Frequency Oscillator, Dual Invertor, Noise Source, Sample and Hold)
  • EA2431 Ring Modulator
  • EA2441 Voltage Controlled Low Frequency Oscillator
  • EA2421 MIDI to CV convertor
  • EA2522 Dual MIDI to CV convertor

Additional Ancillary modules are used to complete the system:

  • EA2800 3″ x 6″ Blank Panel
  • EA2801 6″ x 6″ Blank Panel
  • EA2802 9″ x 6″ Blank Panel
  • EA2901 Power Supply and Back Panel
  • EA2905 Power Supply Front Panel
  • EA2906 Multiple Panel

Custom built Oak cabinets are made to order with the following dimensions:

  • EACAB1  42” x 12” Oak Cabinet
  • EACAB2  42” x 18” Oak Cabinet
  • EACAB3  42” x 24” Oak Cabinet
  • EACAB4  24” x 24” Oak Cabinet

The “Tribute” System

Nearly 50 years ago in the early 70s two Californian university graduates, Dave Rossum and Scott Wedge, set up a small company making a high quality modular synthesizer. The company they formed was called E-mu and from the humble beginnings of their modular system they went on to produce a whole host of innovative electronic instruments.

The E-mu Modular system is a classic and it was pioneering. The Exclusively Analogue modular system project was started to fulfil the need I had to re-house my original E-mu system submodules and developed from that. It was built as a tribute to the E-mu pioneers and hence it was called “The Pioneer Tribute” modular.

The primary modules, Voltage Controlled Oscillator (VCO), Sawtooth Pulse VCO (SPVCO), Voltage Controlled Low Pass Filter (VCLPF), Dual Transient Generator (DTG), and Voltage Controlled Amplifier (VCA) have been faithfully recreated, also as a tribute to the E-mu modular, to ensure the same sound.

There were only 5 complete systems built, including mine, but several original systems were repaired and enhanced with the new modules.  If required, replacement sub-modules, such as VCO and VCF, for most of the original E-mu modules can be produced to get a system working again.  I am extremely grateful to Dave Rossum and Rob Keeble for their help with completing this project.  I had the privilege to meet Dave, ‘Mr E-mu”, in California and to see some of his new Eurorack synthesizer modules.

The Pioneer Tribute contains the modules listed below. The modules that have web links are available in limited quantities as stand-alone modules.

Additional Ancillary modules are used to complete the system;

  • EA2800 3″ x 6″ Blank Panel
  • EA2801 6″ x 6″ Blank Panel
  • EA2802 9″ x 6″ Blank Panel
  • EA2905 Power Supply Panel
  • EA2906 Multiple Panel
  • 42” x 12” / 24” x 24”  / 12”  x 24” Oak Cabinet
