Neutron Sound - Orgone Accumulator


Being an unusual and feature packed digital oscillator this module is able to create a vast number of sounds and timbres, from soft and subtle to outrageous and intense. This wide spectrum is made possible by dynamic waveform crossfading, FM, AM, dual VCO sync, wide detune, filter-like harmonic modulation and effects as well as a drum mode. Of course it gives you voltage control in abundance.



The Orgone Accumulator simultaneously produces three waveforms, Wave A, B and C between which the SCAN parameter dynamically blends. The red controls in the top left corner select the waveforms for A, B and C from a plethora of waves, from sine to complex material.

TUNE sets the oscillator's pitch in semitones, FINE is responsible for the fine tuning. When TUNE LOCK is activated unintentional changing of the tuning can be prevented.
DETUNE can be activated per wave and derives from a single one a number of waves which are detuned against each other. This widens the sound a lot, can produce rave-ish sounds and even geenrate chords. A hate at the RESET input will reset the detuned VCOs, creating a pulsating-percussive sound.

Amplitude and Frequencys Modulation (AM and FM): INDEX sets the modulation intensitiy, MOD WAVE the waveform of the modulator. The FIX button quantises in FM mode the frequency ratio between carrier and modulator to semitones.

Also integrated are eight effects which are activated with FX SELECT. The EFFECT parameter simultaneously determines modulation intensity and choses one of two variations (bipolar control, one variation to the left, one to the right).

  • Detune: the original Orgone's five oscillators, detuned
  • Twin: two oscillators with CV phase offset and anti-cancellation. left = down, right = up
  • Dist 1: left = bitcrush with smooting the crushbit number, right = wave folder
  • Dist 2: left = XOR effects, right = a self-modulation which bends waves by itself
  • Chord: generates chords. left = minor, right = major
  • Spectral: instead waves each value is a organ-like arrangement of harmonics. Set global waveform with MOD WAVE.
  • Delay: MOD FREQ sets delay time, MOD wave the modulation frequency. EFFECT left = negative feedback, right = positive feedback.
  • Drum: a complex drum voice with crossmodulated noise. Almost every control has a new function.

Not having a manual the functions of the PulS and CX buttons aren't clear to us.
