Oscillator 1

Octave: the range is from 64’ to 1’ (7 octaves); please note

that the standard range for a piano is 8’ and this means that,

by setting the related control to the middle position, any key

played on the keyboard will play with the same frequency of

a standard piano (the Sledge keyboard is from C2 to C7 while

the standard 88 notes piano range is from A0 to C8)

Semitone: it allows to change the basic semitone (+ and + 12

semitones = 2 octaves)

Wavetable: this unique function, allows to select a number of

waveforms of dierent kind and harmonic content, allowing

many dierent sounds normally not obtainable by the typi-

cal analogue waveforms. 66 dierent waveform are available

and a more complete description of their harmonic content

will be made available separately.

When a Wavetable is selected (by the Shape button) the re-

lated Potentiometer allows to continuosly modify the star-

ting point, allowing to obtain almost innite nuances and

dierent harmonic contents. The same potentiometer (as it

is shown by the clear front panel labelling) is used to control

the Pulse Width, if a pulse shape is selected.

All other waveforms are typically associated to vintage analogue synthe-

sizers; note: the parameter doesn’t necessarily set only one waveform, but

sets a specic oscillator model that could produce a number of waveforms

depending on other settings. A good example for this behaviour is the

Pulse shape.

A Pulse waveform contains certain harmonic partials according to its width

and it is normally lacking all the harmonics multiple of its duty cicle: as an

example, a pulse having a duty cicle of 25% (1/4) will not have the 4th, 8ve,

16th, 32th harmonic etc. This waveform normally produces a hollow / me-

tallic sound. If the Pulse waveform is selected, the parameters Pulse width

and PWM (LFO section) are used to change the pulse width of the wave-

form. Furthermore, the modulation destinations PWM has a consequent

functionality, depending on which oscillator is set to Pulse.

• A Sawtooth wave has all the harmonics of the fundamental frequency in

descending magnitude

• The triangle mainly consists of the odd harmonics with very low magnitu-

des, while the Square wave has all odd harmonics (and it can be obtained

by also setting the Pulse width to 50%)

• Sine consists of the fundamental frequency only and consequently it has

no harmonics at all.
