EXTERNAL SIGNALS
Processing External Signals
External Signals
Solaris provides extensive processing capabilities for
external signals routed through the synthesizer. External
signals can be routed in via one of the four analog inputs
or the S-PDIF jacks on the rear panel. These inputs appear
in source lists as Input1, Input2, Input3, Input4, SPdifL and
SPdifR, respectively.
Processing External Audio
Signals
External audio signals are essentially played “through” the
Solaris. Though you can process them as you would the
oscillators, it’s important to remember that the external in-
puts are not polyphonic. No sampling or pitch shifting or re-
synthesis is involved. Just holding down one key (or using
the Hold button and playing one key) will be all you need
to hear external audio as it is routed through the synth.
Pressing multiple keys will just give you the same signal,
but louder, for each key pressed.
The external inputs are on the Audio Source List, and
therefore can be routed just like the oscillators. You can
filter them (in parallel or in series with the 4 filters), use the
insert FX with them (pre- or post-filter), even use them as
inputs to the Rotors, Vector Mixers, or AM sections. Plus,
you can derive an envelope with the envelope follower (see
“Envelope Follower (EGFoll)” on page 43) for any of the
external ins to sweep the filter cutoff or modulate other pa -
rameters. You can even use them with the lag processors
for simple 1-pole filtering, as described in “Lag Processor”
on page 43.
Using external ins with the Vector Mixers allows you to
quad mix 4 inputs with the Joystick . Using them with the
AM sections (such as the Ring Mod algorithm) allows the
external ins to interact more with the oscillators, and vice
versa. Or, you can just use them as Mod Sources to control
an oscillator’s frequency directly.
An additional comment about using external audio signals
with the Rotors: because the Rotors can run at audio rates
like oscillators do, you can use the Rotor to give a “pitch”
to external audio signals, and play them polyphonically that
way. The source material doesn’t even have to be pitched.
You could use traffic sounds, crowd noises, or strange elec -
tronic blips and beeps, and then just run the Rotor as an
oscillator. The external inputs will provide the raw material
for the Rotor’s timbre, and the Rotor’s tuning controls and
the keyboard will control the pitch or frequency.
Processing External Control
Signals
Control signals from external synthesizer gear, such as a
modular LFO module, can be passed in to Solaris via one
of the four analog inputs. This signal can then be used as a
control source within Solaris to modulate other parameters,
thus providing a way to easily synchronize parameters in
Solaris to external analog gear.
