Quetzalcoatl quick guide
Quetzalcoatl is essentially 8 sample based synth voices stacked together with independent control over several key parameters. In traditional synthesise terms you could say a single Quetzalcoatl “voice” in has a signal chain something like this:
VCO (sample) > VCA (pre XF Gain) > VCA (For X-Fade) > - Filter - VCA (envelope).
In Quetzalcoatl, one of these voices is called a stage.
Apply several different crossfading and layering effects to the 8 voices.
- X-fade - crossfade between the voices
- Fade Mode - Select one of five x-fade modes
- Stages - Select between 8, 4 & 2 active voices*
- Smooth - Smooths out the levels between crossfades
- Mod - Applies modulation to the x-fade
- Vel - Applies velocity modulation to the x-fade
- AT - Applies channel aftertouch the x-fade
- Trk - Applies keyboard tracking to the x-fade
*Reducing the number of stages should improve performance.
Use the stages menu to switch between pages.
- Tuning - The 8 sliders control the pitch of a single voice
- Pitch mode - Select one of several pitch modes. These will lock (or not**) the pitch of the voice to a particular scale or tuning. When this is set to "off" CPU use will be decreased significantly.
- Offset - Offsets the relative position of each of the tuning sliders
- Mod - Applies modulation to the offset value
- Vel - Applies velocity modulation to the offset value
- AT - Applies channel aftertouch the offset value
- Trk - Applies keyboard tracking to the offset value
- Mod 1-8 - Per stage modulation
- Glide 1-8 - per stage glide
- Transpose - Transposes stages by semi-tone. Values are updated on next keypress. These controls work even if pitch mode is set to off.
- Gain - The 8 sliders control the gain (pre Xfade) of a single voice
- Offset - Offsets the relative position of each of the gain sliders
- Mod 1-8 - Per stage modulation
- Out 1-8 - Sets the output channel when using the Multi-output plugin
- Cutoff - The 8 sliders control the cutoff of a single voice
- Mode - Select between low pass, high pass, band pass, all pass, ring mod & fold filter modes. When set to off CPU usage will be reduced
- Offset - Offsets the relative position of each of the cutoff sliders
- Mod - Applies Modulation to the cutoff offset
- Vel - Applies velocity modulation to the offset value
- AT - Applies channel aftertouch the offset value
- Trk - Applies keyboard tracking to the offset value
- **Mod 1-8 ** - Per stage modulation
Wavefolder
- Fold - The 8 sliders control the amount of wavefolding on a single voice
- Offset - Offsets the relative position of each of the fold sliders
- Range - The range of the wavefolder, at maximum the folder will go from near silence to extreme distortion.
- Cut - The cutoff of the lowpass filter
- Q - The resonance of the lowpass filter
- Envelope - A standard ADSR envelope controlling the gain
- Vol - Controls master volume
- Vel - Velocity modulation of the master volume
- Pan - 8 sliders control the pan of each of the voices
- Load Expansion - Select an expansion pack to load
- Presets - load, save and manage presets
- Samples - Load multi-samples, change sample modes, import user waves and SFZs
Load and manage sample files.
Polyphonic modulators start with each key press.
- On/Off - Turns the modulator on or off. Disabling poly mods can significantly reduce CPU usage.
- Tempo - set the tempo of the step and LFO modulators
- **Div **- Divide the tempo rate
- Modę - switch between step, table and envelope modes
- One shot - The modulator only plays once
- Steps - set the number of stages in the step modulator
- On/Off - Turns the modulator on or off. Disabling mono mods can somewhat reduce CPU usage.
- Tempo - set the tempo of the step and LFO modulators
- **Div **- Divide the tempo rate
- Modę - switch between step and table modes
- One shot - The modulator only plays once
- Steps - set the number of stages in the step modulator
- Mod - Modulate the tempo
- Trig - set a trigger source (free, on key press or another modulator)
