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 Explorer has 3 oscillators per voice. Oscillators 1 and 2 can operate in two different 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 different.
The Mutant modules affect an oscillator the same way a mask or lipstick affect 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 difference 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
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.
