Iridium Keyboard Quickstart
Oscillator Section
Iridium Keyboard offers three oscillators with different
capacities:
Wavetable
,
Waveform
,
Particle Generator
,
Resonator
, and
Kernel
synthesis.
r
If you press an active oscillator model button, the
current oscillator is switched off completely. This gi-
ves you a better overview when editing sounds be-
cause you can use it as a mute function.
r
For each synthesis type, we have included
Presets
with which you can quickly create your own sounds
and explore the possibilities of synthesis.
The Wavetable Oscillator
Iridium Keyboard offers a wavetable oscillator.
=
Press the Wavetable button to acti-
vate the Wavetable oscillator for the
corresponding oscillator 1, 2, or 3.
The whole oscillator section lights
up in turquois.
A wavetable is a table consisting of single cycle waveforms.
Each waveform is classified by its own special sound cha-
racter. The main difference of wavetable synthesis in com-
parison with other sound-generation principles is the
ability to not only to play one waveform per oscillator but
also to step through the wavetable via different modulati-
ons, thereby creating wavetable sweeps. The results can be
dramatic – much more so than anything any sample play-
back-based system could ever produce.
This principle offers powerful capabilities. To give some
examples:
•
Each note on a keyboard can access a different wave of
a wavetable.
•
The
Travel
parameter allows a cyclic run through all
waves of a wavetable.
•
An LFO or envelope can modulate the position within
the wavetable. You can create subtle to drastic sound
changes.
•
User-selected controllers, such as the Mod wheel, can
change the position within the wavetable. When you
turn the wheel while playing a chord, each note’s wave
will be modified instantly.
