5.1.5 Mono Mode and Poly Mode in the Master Channel
The modules in the Master Channel have two operating modes: Poly mode and Mono mode.
You can switch between both modes by clicking on the Mono/Poly switch:
Mono/Poly switch
•
In Mono mode (three arrows meeting each other), the signals coming from the three
Channels A-C are summed up before being processed by the module.
• In Poly mode (three parallel arrows), the module processes each Channel separately.
!
As a logical consequence, you cannot have a module in Poly mode sitting after a module
in Mono mode, since the three Channel signals have already been summed up by the
rst module…
The difference between the two modes can be heard particularly clearly in the Waveshaper
module: In Poly mode every voice has its own, independent Waveshaper. The distortion affects
every voice separately – in the same way as if every string on a guitar had its own amplier.
In Mono mode, only one Waveshaper is used for the different voices, which means that many
of the notes played interact – similar to the way that they do in chords played on a distorted
electric guitar. You can try out the effect simply by inserting a Waveshaper module into the
Master Channel. Play a couple of sounds and switch between both modes by clicking on the
Mono/Poly switch. You will see that the Mono mode reacts with signicantly stronger distor-
tion as you begin to play multiple notes. This is because the signals of the different voices
are assembled before the Waveshaper input, which results in a higher input gauge. In Poly
mode, by contrast, the voices are distributed among multiple Waveshapers and thus produce
lower signal levels.

For low level input signals, the Waveshaper in Mono mode works like a simple compressor
and lends itself well to compressing and heating up the input signal.
