The Oscillator Group
Oscillators are the foundation of a patch. They generate the most basic component of the
sound, which is then shaped by other components such as Mutants, Filters, Envelopes, etc.
Hydrasynth has 3 oscillators per voice. Oscillators 1 and 2 can operate in two dierent modes:
Single and WaveScan. Oscillator 3 operates only in Single mode. The same waveforms are
available in both modes, but the features of each mode are very dierent.
The Mutant modules aect an oscillator the same way a mask or lipstick aect a face: they
change the way the underlying component is presented to the world. The Ring-Noise module
does a similar thing: it produces a sound based on the sum and the dierence of two input
signals.
The Oscillator, Mutant, and Ring-Noise modules form the Oscillator group. We’ll cover them all
in this chapter.
Settings can be copied between identical modules (Osc 1 and 2, Mutants 1-4): Hold
[SAVE], press and release the source, and then press and release the destination. Then
release [SAVE].
Oscillators 1 and 2
The features of these oscillators are identical, so the following descriptions apply to both. For a
list of the available waveforms see the Waveform List (p. 40) at the end of this chapter.
Switching modes
To change an oscillator from Single mode to WaveScan mode or vice versa, access [OSC 1] or
[OSC 2] and use Control knob 1.
Single mode
Single mode provides only a single waveform to the sound, hence the name. There’s a lot you
can do with a single waveform, though: the Mutant modules and the Ring Modulator make sure
of that.
Single mode has one page of parameters.

(see Waveform List (p. 40))
Choose a waveform as the starting point
Semi +/- 36 semitones Coarse tuning of oscillator pitch. Use [SHIFT] to
jump by 12 semitones.
Cents +/- 50 cents Fine tuning of oscillator pitch
Keytrack 0-200% Sets keyboard pitch tracking. 0 = xed pitch;
at 200% a 1-octave dierence on the keyboard
changes the pitch by 2 octaves. Default = 100%.
