Moog Matriarch - Amplitude Envelope Generator

29
Matriarch is equipped with two Voltage-Controlled Amplifiers, VCA 1 and VCA 2.
Before the sounds created by Matriarch can be output and monitored through
speakers or recorded, they pass through a pair of VCAs and are brought to an
appropriate level. The Output module controls will determine how the final sound
is heard. By default, VCA 1 controls the Left channel output level and VCA 2
controls the Right channel output level.
MODULE PROVENANCE: Matriarch’s output VCAs are based on the classic Moog 902 module.
MAIN VOLUME
The MAIN VOLUME knob sets the level for the LEFT (MONO) OUT and
RIGHT OUT outputs jack (located in the Audio section on Matriarch’s rear panel).
NOTE: The EURORACK and HEADPHONE output jacks on the rear panel are unaected
by the front panel MAIN VOLUME knob settings.
VCA MODE (Envelope, Split, Drone)
The VCA MODE switch determines which control signals – if any – are changing
the output level of each VCA.
AMP ENV
In the AMP ENV position, the output level of both VCA 1 and VCA 2 will be
controlled by the Amplifier Envelope Generator.
SPLIT
In the SPLIT position, the output level of VCA 1 is controlled by the Filter
Envelope Generator, and the output level of VCA 2 is controlled by the
Amplifier Envelope Generator.
DRONE
In the DRONE position, the output levels of the VCAs are unaffected by either
EG. Instead, the output level is set by a default voltage normalled to the VCA 1
CV IN and VCA 2 CV IN patch points.
NOTE: Matriarch will continue to drone at this level, whether a key is held or not.
