Oscillator Modifiers

4. Triangle Wavefolder:
Effect: Boosts the amplitude of Wave 1 and whenever the oscillators cross the maximum
amplitude limits of the synth the waveform then folds back in on itself linearly.
Control: Controls the amount of gain boost applied to the oscillator (the amount of gain
applied affects how many times the waveform folds).
Tip: For West Coast style timbres try setting Wave 1 to a Sine or Triangle (Wave Bank = 1,
Wave 1 CC = 0 or 32) and set the ADSR's for Amplitude and Filter to the same values.
5. De-Rez:
Effect: Applies a downsampling algorithm to Wave 1 that reduces the amount of
readable points within a wavetable, causing the output to become jagged. The amount
of the downsampling scales with frequency resulting in different amounts of the effect
per note.
Control: Controls the amount of downsampling applied to Wave 1.
Tip: As the effect scales with frequency it is recommended to use higher control settings
for patches that use De-Rez at high octaves.
6. Rise-Over-Run Phaseshaper:
Effect: Reshapes the phase of Wave 1's oscillators so that instead of reading through
the wavetable linearly and generating the normal shape, a different output waveform is
produced instead. This modifier alters the amount of time it takes per cycle for the phase
to reach halfway through the wavetable.
Control: Changes the read curve from linear to fully shaped on Wave 1
Tip: For classic Pulse Width Modulation (PWM) effects, set Wave 1 to a square wave and
modulate the control (Wave Bank = 1, Wave 1 CC = 94).
7. Glitchy Sine Waveshaper:
Effect: Applies a wave-shaping distortion to Wave 1's oscillators that has the amplitude
curve of a bit-crushed sine wave, altering the final output shape and producing differing
harmonics.
Control: Controls the amount of wave-shaping from none to fully processed.
Tip: This effect is subtler than most other modifiers, especially when used with
harmonically rich waveforms, in these cases the effect can be used to introduce extra
high-end partials.

8. Window Amp Sync:
Effect: Similar to Window Sync where an amplitude window is applied to Wave 1,
however the window is played back at a faster rate instead of the waveform which
creates notches in the wavetable shape.
(Note: As the window is always applied to the waveform, this modifier will have an
impact on the sound regardless of whether the control is set to zero, this can act like
filtering with waveforms that have a lot of variation towards their edges).
Control: Controls the playback rate of the amplitude window.
Tip: When heavily modulated this effect works best with simpler waveforms such as Sine
waves. Subtle amounts of modulation can produce interesting phaser like effects when
used with more complex waveforms.
9. Frequency Modulation:
Effect: Wave 2's Oscillators are added to the frequency calculation of Wave 1's oscillators
causing the shape of the waveform playing back on wave 1 to become distorted,
producing complex frequencies.
Control: Controls the Frequency Modulation depth (how much Wave 2 affects the
frequency of Wave 1).
Tip: For more harmonic results it is recommended to set Wave 2's detune value to either
Octaves or Fifths. Whilst Phase Modulation and Frequency Modulation tend to produce
mostly similar results, this version of FM has been scaled to be more extreme than PM, if
trying to get subtler versions of this effect try Phase Modulation.
10. Hard Sync:
Effect: Oscillator sync is performed on Wave 1, with a sharp jump occurring at the phase
reset. Wave 1 is synced to an internal master counter tracking the current playing note,
with the slave frequency being controlled via the "Osc Mod" control. This allows sync
effects to be created without having to use Wave 2's tuning.
Control: Controls the sync slave playback rate (how much faster Wave 1's audible
oscillators are playing back in relation to the master counter).
Tip: This style of Sync is the version found on many synthesisers and works best on
harmonically rich waves, for classic kinds of synced sounds try using this effect on the
Square and Sawtooth waves (Wave Bank = 1, Wave 1 CC = 94 or 127).
