The Oscillator Section - Steinberg HALION4 Mode D'emploi

Octave
Here, you can adjust the pitch in octave steps.
Coarse
Here, you can adjust the pitch in semitone steps.
Fine
This parameter allows you to fine-tune the pitch in cents (hundredths of a semitone).
Env Amnt (Envelope Amount)
This parameter determines how much the pitch is affected by the pitch envelope.
Random
This parameter allows you to randomly offset the pitch with each played note. Higher
values cause stronger variations. At a setting of 100 %, the random offsets can vary
from -6 to +6 semitones.
Key Follow
Here, you can adjust the pitch modulation by MIDI note number. Set this parameter to
positive values in order to raise the pitch the higher you play. Use negative values to
lower the pitch the higher you play. At a setting of +100 %, the pitch follows the
played note exactly.
Center Key
This specifies the MIDI note that is used as the central position for the Key Follow
function.

The Oscillator Section

The Oscillator section for synth zones offers six sound sources: three main oscillators,
the sub oscillator, the ring modulation, and the noise generator. To create interesting
electronic spectra, you can mix any of these sound sources. The resulting signal is
sent to the Filter and Amplifier sections for further sound shaping.
The three main oscillators (OSC 1, OSC 2, and OSC 3) offer different wave shapes
and algorithms.
• To activate an oscillator, click its On/Off button.
To save processing power, deactivate any oscillator functions that are not needed.
