Keyboard Mode and Glide

There are three keyboard modes:

Polyphonic

 : the default mode where each new pressed key creates a new voice.

The maximum number of simultaneous notes can be adjusted with the 

Polyphony

setting. Noxious has a maximum polyphony of 16 voices.

Mono-Retrigger

  :   when   pressing   a   key,   the   synth   retriggers   the   envelopes   and

changes the pitch if a previous key is pressed.

Mono-Legato

  :   this   is   the   same   as  

mono-retrigger

  but   the   envelopes   are   not

retriggered.

By changing the  

Glide

  duration, you can add portamento effect that will make the pitch

glide from the previous note to the next. This also works in  

polyphonic

  mode but in this

case the portamento will take place only if you press a new key will previous notes are in
release mode.

Sound

Architecture

In   Noxious,   you  don't   directly   create   partials.  You
start from a set of partials corresponding to a wave
form   which   you   then   modify.   These   modifications
are done through two “classic” filters and up to five
“modifiers”. All these are applied in sequence to the
partials.   This   architecture   is   summarized   by   a
schematic   on   the   back   panel,   reproduced   on   the
right of this page.

Waveform

The wave form is selected by navigating through the
list of wave forms with the left or right buttons or by
directly selecting it in a list by clicking on the current
wave form label.

Variation

Each waveform has a number of variations (for example pulse width for the sawtooth
waveform) that  can  be selected  in a continuous  manner. Sweeping smoothly between
each variation is a first method of changing your sound over time.
