Summary of Contents for Rob Papen QUAD

  • Page 1 User Guide Powered by RPCX...
  • Page 2 Welcome QUAD is the first Rack Extension synthesizer built from the ground up for Reason by the Rob Papen team. It features two oscillators with a seemingly simple arsenal of classic waveforms. The sonic palette is huge though, through the vast modulation possibilities that QUAD has to offer.

  • Page 3: Patches And Mod Section

    At the top of the QUAD Panel you find the Patch section and modulation controls. Patch Controls QUAD uses the standard Reason Patch controls. A click on the Patch menu displays a list of patches in the current folder. The up and down buttons take you through all the available patches one by one.
  • Page 4 An oscillator is a tone generator. It is the first building block in the sound construction process. The frequency setting of the oscillator determines the pitch of the sound. The selected waveform defines the sound’s tonal character, or timbre. QUAD uses up to 2 oscillators in per voice (note played).
  • Page 5 When oscillator 1 finishes its wave cycle, it reverses the synced oscillator 2 waveform direction Oscillator 2 retains its own pitch, but the reversal of its waveform introduces additional overtones in the oscillator output. It is a much more subtle effect than hard sync. Rob Papen QUAD...

  • Page 7: Oscillator Modulation Functions

    Oscillator Modulation Functions QUAD has a number of different modulation types that allow oscillator 1 to control oscillator 2 and vice versa. Each of the modulation function has Amt 1 and Amt 2 controls to set specific parameters for each modulation function type.
  • Page 8 Frequency modulation alters the output of Oscillator 2 by using the output of Oscillator 1 to alter the frequency of Oscillator 1. QUAD employs cross-frequency modulation, which allows Oscillators 2 to alter the frequency of Oscillator 1. This creates a more complex waveform.
  • Page 9 At low modulation amounts, it would transform a sine wave towards a saw wave. At high levels a chaotic waveform ensues. Amt 1 Sets the modulation amount Amt 2 Sets the balance between self-modulation and frequency modulation. (0 – self , 100% - FM) Rob Papen QUAD...
  • Page 10 Sign uses the polarity of one oscillator to change the polarity of the other oscillator. Amt 1 Sets the balance between the modulated signal and direct signal Amt 2 Sets the direction of modulation between Oscillator 1 and Oscillator 2. Rob Papen QUAD...
  • Page 11 2 Amt 1 Sets the balance between the modulated signal and the direct signal of oscillator 2 Amt 2 Sets the balance between the minimum of oscillators 1 and 2 and maximum of oscillators 1 and 2. Rob Papen QUAD...
  • Page 12 Determines the number of cycles to played from each oscillator Amt 2 Sets the extent at which the oscillator pitch drives the number of cycles played. What follows is a display of a sine wave and a saw wave combined in the Cross algorithm: Rob Papen QUAD...
  • Page 13 Sets the resonance amount String String uses oscillator 2’s output in a string model (Karplus-Strong), to generate plucked sounds. Amt 1 Sets the length of string in the model Amt 2 Sets the level of damping in the model Rob Papen QUAD...

  • Page 14: Phase / Waveshape Distortion

    The waveforms as generated by the oscillators are subject to further modulation through Phase Distortion and Wave Shaping. You select these in the XY Pad section of QUAD as explained in the next chapter. Each Phase Distortion and Wave Shaper type has two controls to define the effect.
  • Page 15 Sets the frequency of the fold-over distortion. Amt 2 Sets the level of the fold-over distortion. Fuzz Fuzz is based on a classic fuzz pedal distortion. Amt 1 Sets the frequency of the fuzz-distortion effect Amt 2 Sets the level of fuzz distortion Rob Papen QUAD...
  • Page 16 Sets the level of the positive wave cycle Oct 2 Oct 2 moves the signal up by one or more octaves. Amt 1 Sets the range of the octave effect. Amt 2 Sets the level of octave effect. Rob Papen QUAD...
  • Page 17 Sets the frequency of the PWM Rez1 / Rez2 Rez 1 and Rez 2 distort the signal based on resonance peaks, Amt 1 Sets the amount of resonance Amt 2 Sets the frequency of the resonance. Resonance 1 example: Resonance 2 example: Rob Papen QUAD...
  • Page 18 Sets the average frequency of the static noise. Trans Trans distorts the transients only. Transient are the sharp peaks that occur at the beginning of waveform. Amt 1 Sets the transient frequency range Amt 2 Sets the level of distortion Rob Papen QUAD...
  • Page 19 Reason manual for details on how to achieve this.. A third method to get those X and Ys moving is through the CV Inputs. On the QUAD Back Panel you will find CV inputs for the X and Y values for each of the Pads. The control voltage used on these inputs determines the X and Y values.

  • Page 20: Filter Type

    Filters 1 and 2 QUAD includes two high quality analogue modelled filters that apply subtractive filtering to the soundwaves generated by the oscillators. The filters have their most used modulation parameters hard-wired in the QUAD structure, such as Envelope, Velocity and Modulation Wheel. This makes sound editing easier and faster.
  • Page 21 This is an additional 12 dB LowPass filter with an alternative tonal character 24dB HighPass High frequencies pass through this filter; those below the Cutoff frequency are reduced by 24dB per octave. The filter is fully open if the Cutoff frequency knob is turned fully counter-clockwise. Rob Papen QUAD...
  • Page 22 Cutoff frequency are reduced by 36dB per octave. 36dB HighPass High frequencies pass through this filter; those below the Cutoff frequency are reduced by 36dB per octave. The filter is fully open if the Cutoff frequency knob is turned fully counter clockwise Rob Papen QUAD...

  • Page 23: Filter Controls

    Vowel In the Vox filter this controls the vowel of the filter. For Formant 2 / 4 filters, it controls the separation of the filter bands. Rob Papen QUAD...
  • Page 24 Typically, the harder you strike the keys, the more the filter opens. When you use negative modulation values the filter closes with increasing velocity. If QUAD is in sequencer mode (Play mode) the sequencer velocity settings drive the filter frequency.
  • Page 25 Patches in a Folder. Velocity (Vel) The Velocity control determines how the sound’s volume responds to changes in note velocity. It applies to notes played on a keyboard and those triggered by the QUAD sequencer. Velocity shape The velocity shape changes QUAD's velocity curvature response to the keyboard input or host input.
  • Page 26 0% in the time set by the fade control. The envelope release stage starts when you release a key. The envelope fades out from the sustain level to 0% in the time set by the release control. Rob Papen QUAD...

  • Page 27: Modulation Section

    Modulation section You find QUAD’s modulation section in the bottom right hand corner. This section holds 2 Envelopes, 2 LFOs and a modulation matrix with 8 slots. The modulation section is a treasure trove for subtle or complex sound-shaping options.
  • Page 28 Sync is a switch that enables automatic triggering of the envelope, synchronised to Reason’s tempo setting. LFO 1 and 2 The QUAD modulation section has two LFOs. Both LFOs have an identical set of controls to determine their behaviour. Waveform type The available waveforms are Sine, Triangle, Saw Up, Saw Down, Square and S&H.
  • Page 29 LFO the range goes from 25% up to 400% which is from 25% of the original speed (i.e. ¼ as fast) to 400% of the original speed (i.e. 4 times as fast). The destination column lists which parameter is subject to the programmed modulations. You have a choice of 119 destinations here. Rob Papen QUAD...
  • Page 30 Arpeggiator QUAD incorporates a classic style arpeggiator that plays notes one after another, drawing from all keys that are held down. The playback order happens in a variety of octaves and patterns. The arpeggiator has a built-in pattern sequencer. Each step of the pattern sequencer has individual on/off and velocity settings.
  • Page 31 The Vel / Key control sets the balance between these. Step 1 – 16 On/Off Click on a step number to mute and un-mute it. Rob Papen QUAD...

  • Page 32: Play Mode

    QUAD will stack multiple voices for every not played Unison In Unison mode, QUAD plays multiple voices, for each note played. The Unison detune parameter makes that these voices can be detuned slightly from each other. Ultimately this gives you an extremely rich sounding stack of voices. The unison parameters are an excellent tool to create fat lead sounds.
  • Page 33 This mode works the same as constant rate, but only affects overlapping notes (legato style) Held Time This mode works the same as constant time, but only affects overlapping notes (legato style) Port This control sets the rate or time for the portamento effect. Rob Papen QUAD...

  • Page 34: Effect Types

    FX section Each QUAD Patch incorporates up to two independent high quality effects. The effects are connected in series. Each effect type comes with default parameter settings and can be used straight away upon selection. If you make any changes to the effect controls however, it will remember these.
