LinPlug Alpha - Manual (Page 7)

Overview
There are multiple versions of the Alpha synthesizer available: the full Alpha, a couple of
custom Alpha synthesizers with a somewhat reduced set of features and the Free-Alpha
which is publicly available but has the least features.
See the Appendix F on page 32 for the differences between the various versions of Alpha.
This manual describes the Alpha so some parts may not be applicable to the custom
versions of Alpha and the Free-Alpha.
The Alpha synthesizer is a 32 note-polyphonic AU and VST synthesizer based upon a
classic subtractive design. It includes three oscillator modules, a filter module, two envelopes
and three LFO modules, a chorus effect and an easy-to-use yet powerful Modulation Matrix.
The structure of the main edit page can be divided into several sections: Oscillators, Filter,
Amplifier, Modulation Matrix, LFOs, Glide, Chorus and Master.
Audio signals are generated by the oscillators when the Alpha receives a Note-On from your
DAW software. The Alpha contains three oscillators from which one generates noise only.
The other two oscillators create a fixed mix of two waveforms each. Pitch, amplitude and
symmetry can be modulated using the Modulation Matrix (Noise can be only modulated in
amplitude). Moreover the second Oscillator hast a Ring Modulation unit integrated.
The output of all three oscillators is mixed and routed to the Filter section. The filter modifies
the harmonic spectrum of the mix and has its own dedicated envelope for controlling the filter
cutoff parameter. The Filter also can be cross-modulated from one of the three Oscillators
(Filter FM).
The output of the Filter section is then sent to Amplifier section, where it is shaped in volume
and finally sent to the Chorus section. The Chorus feeds the Alpha output which sends the
audio to your DAW's channel mixer. In your DAW you can set the pan position of the Alpha's
output and apply additional effects.
At various points throughout the signal path you can modulate the signal using either
envelopes, LFOs, MIDI controllers or other sources. The Alpha contains 2 independent
envelopes and three LFOs that can be routed to any available modulation destination.
