LinPlug Spectral - Manual (Page 11)

Overview
Spectral is a 32 note-polyphonic synthesizer with some extraordinary
features.
Audio signals are created by the Oscillators. They get triggered from your
host software (DAW software). The Notes might come from a prerecorded
track or being played life from your Keyboard, Guitar or whatever Controller
you use to play your music.
The output of each Oscillator is sent to its dedicated Filter. Moreover each
Oscillator can be used simultaneously as a cross-modulation source in any
Oscillator or Filter. This cross-modulation increases the harmonic spectrum
of the modulated Oscillator or Filter producing very interesting results.
At this point the signals can also be thickened and spread in the stereo
panorama using the Spread (polyphonic Unison) controls.
Most Oscillator parameters can be modulated using the Mod-Matrix.
The Filter modifies the harmonic spectrum of the Oscillator signal. Each
filter includes a dedicated envelope for controlling the filters operation
frequency. The filter can also be used as a cross-modulation source. The
filtered signal then can be panned and routed to either one or two effect
units. Most filter parameters can be modulated using the Mod-Matrix,
including the routing.
Following the Filter section is the Spectral's effects section which contains
6 independent effects processors plus a Master EQ. A wide range effect
processors are available including delays, chorus, phaser, filter and many
more.
The effects routing is quite flexible allowing each effect to go to any of the
successive effects or the Master EQ.
The Modulation sections contain the instrument’s 12 Envelopes, 5 LFOs,
Glide, the Arpeggiator and the Modulation Matrix (or in short Mod Matrix).
At various points throughout the Spectral’s signal path you can modulate
the processing parameters using the various controls found in this sections.
Independent from the internal modulation sources every MIDI Controllers
can be used to modify any of the Spectral’s parameters (using MIDI Learn)
and the most common Controllers can be used in the Mod Matrix (for
example Velocity, the Modulation Wheel or the Expression Controller).
