The AM goes from VCO2 to VCO1 (VCO2: carrier, VCO1: modulated) via
AM
. The process
is made after the VCOs and before entering the HPF and VCA stages.
The FM is through Zero FM. It is from VCO1 to VCO2 and vice versa and it is controlled via
the
FM
and
XFM
faders. This process directly affects the VCO frequency.
A more complex way of using the AM and FM can be achieved using envelope 1. The
process consists of sending the carrier via a VCA controlled by Envelope 1. The output is
sent to the AM or FM system. This process can be used to make portions of a sound with
modulation, while the rest without it. It is available via
ENV1>AM
and
ENV1>FM
(only from
VCO2 to VCO1). The signal flow is illustrated below:
5.5 Mixer
This is a two-channel mixer that sets the volume of VCO1 and VCO2 after all the modulation
processes and VCA amplification.
V1 MIX
sets the level of VCO1 (which includes the FM
and AM processes).
V2 MIX
sets the volume of VCO2 (which includes the XFM process).
The wave sent to channel 2 is the
FM WAVE
.
5.6 HPF
After the mixer there is a 6db high pass filter used to cut the low-end frequencies. It is
controlled by
HPF1+2
. At its minimum position, the sound passes through without any
change.
