cut-off.
The default configuration for the Gigmate v2 is to have envelope 1 control filter cut-off and/or other attributes
such as pitch, while envelope 2 is used exclusively to control volume. However, by switching to ‘envelope 2’
in the filter section, you can have envelope 2 control both volume and filter cut-off, whilst reserving envelope 1
for other purposes.

The Gigmate v2 does NOT conform to the ADSR type configuration. Instead, it has controls for
‘Attack’ and Release’ only. These are named ‘Rise Time’ & ‘Fall Time’.
With the sustain switch set to ‘in’, the envelope will hold its peak value until the key is released,
at which point the ‘fall time’ stage will kick in.
With the sustain switch set to ‘out’, the envelope will proceed to the fall time as soon as the
attack phase is completed.
If a held key is released before the attack phase is completed, the fall time will kick in immediately.

The envelope can be used to control filter cut-off; the extent of it’s influence can be determined by
the ‘env’ slider in the filter section. There are some caveats to this general principle, described later in
the section; ‘Envelope To Filter Clipping.’
The envelope can also be used to control output level (volume).
Within the confines of the master volume knob, the Gigmate’s output level is controlled by an amplifier
inside the instrument, the ‘VCA’ (Voltage Controlled Amplifier).
The VCA is controlled using this switch. When switched to ‘continuous,’ the VCA
remains at full gain. When switched to ‘keyed’, the VCA switches to full gain
when a key is pressed, but if no keys are pressed, it will close the output down
to zero. When switched to ‘contoured’, the envelope will control the VCA gain.
Please note that the Polyphonic Section has no ‘release’ and can not be heard once a key is released.
