multaneously to activate the Kernel mode for the cor-
responding oscillator 1, 2, or 3. The whole oscillator
section lights up in pink.
So what, exactly is Kernel synthesis? Simply speaking, it is
a modular approach in which up to six audio kernels can
be freely combined into a single oscillator. Effectively, each
kernel is an oscillator in its own right, realising a whole
range of timbres – from using sine and classic waveforms
via wavetables through to samples and noise. For example,
users could combine three wavetables with a sample, a
sine wave, and noise within a single oscillator.
On top of that, the kernels could modulate each other in
audio rate using a variety of modulation methods, such as
amplitude, frequency, phase, and ring modulation. Phase
Distortion is also possible alongside unusual processes like
audio rate wavetable- position modulation. Moreover, each
kernel, of course, could also add self-modulation like clas-
sic FM feedback.
Furthermore, each kernel has its own multi-stage envelo-
pe, stereo output panning, plus multiple modulation opti-
ons for velocity, various key tracking possibilities, plus
presenting feedback, level, pitch, and wavetable position as
modulation targets in the Iridium’s Modulation Matrix.
Meanwhile, kernel pitch can be set in relation to note pitch,
as well as being set to fixed frequency in audio or LFO
range. Pitch envelopes could be also applied to each kernel
individually using the Iridium’s Modulation Matrix.
It is perfectly possible, then, to view Kernel synthesis as an
oscillator construction kit, allowing for traditional approa-
ches like a six- operator FM synth, as well as providing an
experimental space for future-facing synthesis techniques.

Here is a short example how to explore kernel
mode:
1) Choose “Init” from the Load page.
2) From Osc1 Control page choose VCA or DF100
Fil 0 as “Osc1 Dest” for stereo fun.
3) Press Wavetable & Waveform buttons simulta-
neously to put Osc1 in kernel mode.
4) Choose from top left “Templates” menu any item
you like.
5) Each template assigns the 5 OSC 1 pots to indivi-
dual sound shaping parameters.
6) Turn knobs and make sound.
7) Choose another template.
8) Get lost!
