A Short Overview
25 Iridium Keyboard Quickstart
The Waveform Oscillator
Iridium Keyboard offers a standard oscillator model to
create typical analog waveforms.

Press the Waveform button to acti-
vate the Waveform oscillator for the
corresponding oscillator 1, 2, or 3.
The whole oscillator section lights up in green.
Iridium Keyboard provides typical analog synthesizer
waveforms (sawtooth, triangle, etc.), plus other classic
waveforms like square (which is the father of the pulse
waveform) and the sine wave (also part of every other
waveform). Also, different noise signals can also be choo-
sen.
The waveform oscillator can generate up to eight oscillator
signals (called Kernel) simultaneously. Here, you can pro-
duce supersaw-like waves, for example.
The Warp parameter morphs a waveform into another
waveform, depending on the selected one. For example, a
double saw wave can be blended into a regular saw wave
to a square wave.
The Particle Generator
This generator creates its sound by playing back audio
samples.
=
Press the Particle button to activate
the Particle Generator for the corres-
ponding oscillator 1, 2, or 3. The
whole oscillator section lights up in
blue.
There are two different ways of sample playback: normal
playback and granular playback.
The Particle Generator needs to be fed with one or more
samples. The Particle Generator can use one single sample
as well as multi samples that are mapped over the key-
board.
Granular synthesis is based on a simple idea: instead of
playing back an entire sample, only short portions of the
sample – the so-called grains – are played. These grains
can be played back in any order. Each time a grain ends, a
new one starts. To avoid discontinuities in the playback,
and to minimize artefacts, envelopes are applied to the
grains. Granular synthesis can be used to extract interes-
ting spectra from all kinds of samples creating sound
effects by completely scrambling a sample, or for low-
fidelity time stretching, for example.
