Oscillators

SKULPT synthesiser features 2 unique morphable waveform oscillators identified by Wave 1 
and Wave 2 labels. It has a total of 32 oscillators inside, that’s 4 voices with 8 oscillators per 
voice.

• 

Wave 1:

 This encoder allows you to sweep continuously thru the waveforms from Sine - 

Triangle - Saw - Square - PWM.  

• 

Wave 2

: This encoder allows you to sweep continuously thru the waveforms from Sine - 

Triangle - Saw - Square - Noise - Low Pass Filter  down to -inf dB. 

• 

Mix:

 The Mix encoder allows you to balance the volume between each wave. All the way 

to the left you will hear only Wave 1, All the way to the right you will hear Wave 2. In the 
centre you will hear a balanced blend of both waves. 

• 

Fine

: Holding the Shift key and turning this encoder allows us to control the fine tuning 

of Wave 2 (Fine) +/- 100 cents

• 

Tune:

 Holding the Shift key and turning this encoder allows us to control the coarse 

tuning of Wave 2 (Tune) at desirable int/- 4 octaves.

Note: assigning modulation to the Tempo / Swing knob will control the Global Tune of 
the oscillators.

• 

FM:

 Holding the shift key and turning this encoder controls the FM amount between 

Waves where Wave 1 is the carrier and Wave 2 is the modulator. This means that Wave 2 
is modulating Wave 1 up to a maximum of +/- 4 octaves & 100 cents. 

Because of the wide range of Wave 2 detune and the flexibility of the LFOs, this can be 
used to create a huge array of effects, from adding rich harmonics to interesting low-
frequency modulations.

• 

Ring Mod:

 Holding shift and pressing the LFO2 button causes ring mod to be enabled 

and disabled. By default Ring Mod is disabled. Enabling it will cause the LFO 2 LED to 
flash in an on or off direction, depending on whether LFO 2 is being edited or not.

Ring modulation is a form of amplitude modulation where a modulating wave (Wave 1) 
affects a carrier waveform (Wave 2). The effect generates new harmonics that are the 
sum and difference of all frequencies present in the two waves used to generate the 
effect, but this also causes the original frequencies in the carrier signal to disappear. 

Filter

SKULPT synthesiser uses a Modal designed state variable 2-pole resonant filter (capable of 
morphing from low pass, through band pass, to high pass).

• 

Cutoff:

 This parameter controls the low-pass filter cutoff frequency. This affects the 

cutoff frequency of the filter, from 0Hz up to 20kHz.

• 

Reso

: This parameter controls the amount of resonance of the filter. 

• 

Filt-EG:

 Holding the shift key and turning this encoder allows bipolar control of the Filter-

EG amount. (See the Envelopes section)

• 

Morph

: Holding the shift key and turning this encoder allows control of the shape of the 

filter: note that the filter is low-pass by default.

- At it’s minimum value you have a low pass filter; 

- We move through a sort of low-shelving; 

- At It’s midpoint we have a band-pass filter; 

- At it’s maximum value a 1-pole high-pass filter.

TIP: With this feature at lower settings you can dampen the low frequencies while 
maintaining a rich high-end texture.
