Dixie II+ Manual


The Dixie II+ is a fully analogue triangle-core oscillator capable of generating 5 different waveforms plus a square wave sub-oscillator.


See the Module Installation Guide for instructions on installing the module in your Eurorack modular system.

Front Panel



    This 8-position switch is used to set the coarse tuning of the oscillator. Each position shifts the tuning by one octave. Fine adjustment can be made using the FINE knob. Note that when in LFO and with the FINE knob turned up the oscillator may hit the upper limits of the LFO frequency range when the switch is in the higher octave settings.
  2. EXP/LIN
    This switch selects the mode of the FM1 input between linear and exponential response.
  3. FINE
    When in VCO mode this knob functions as a fine adjustment for the tuning frequency. The range is approximately +/- 6 semitones from the centre position. When the oscillator is in LFO mode the range of the knob is much higher, approximate +/- 7 octaves.
  4. VCO/LFO
    This switch switches the Dixie II+ between VCO and LFO mode. When in VCO mode the oscillator operates at audio rates with frequencies between 20 Hz up to almost 60 kHz. When in LFO mode the it can achieve cycles from several minutes in length up to low audio rates of around 1 kHz.
  5. FM1 Attenuator
    Attenuator for the FM1 input.
  6. PWM Attenuator
    Attenuator for the PWM input.
    This knob sets the base pulse width of the PULSE output.  When fully counter clockwise the output will produce a narrow 10% duty cycle pulse, when fully clockwise it produces a pulse with a 90% duty cycle. A square wave is produced with the knob in the 12 o’clock position. The knob is summed with the PWM input.

Inputs & Outputs

  1. FM1
    Linear or exponential frequency modulation input. The behaviour is set by the LIN/EXP switch.
  2. FM2
    Exponential frequency modulation input.
  3. PWM
    This input is summed with the PULSE WIDTH knob to set the width of the PULSE output. The range is +/- 5 V. Note that the width can go down to 0% and up to 100% at which point no wave will be produced.
  4. 1V/OCT
    Primary pitch voltage control input.
  5. SYNC
    When the input waveform crosses zero the oscillator is also reset to zero.
  6. FLIP
    This input functions similarly to the SYNC input except that instead of resetting the oscillator to zero it flips the direction of travel.
  7. SINE
    Sine wave output.
    Triangle wave output.
  9. ZIG-ZAG
    Zig-zag wave output.
  10. SAW
    Saw wave output.
  11. PULSE
    Pulse wave output. The width of the pulse is controlled by a combination of the PULSE WIDTH knob and PWM input.
  12. SUB
    Suboscillator output. Produces a 50% duty cycle square wave with a frequency one octave below that of the primary oscillator.
