Envelope Generators - Moog LABYRINTH User Manual

ENVELOPE GENERATORS

Labyrinth contains two envelope generators. EG1 can be routed to modulate VCO FREQUENCY, MOD
VCO FREQUENCY, VCW FOLD, or VCF CUTOFF via the labeled bipolar attenuators next to their
respective controls. EG2 is normalled to control the VCAs of both the VCW signal path and the VCF
signal path. Each envelope generator is a decay-only envelope triggered by the resulting sequencer
trigger mix via EG TRIG MIX.
EG1 DECAY
EG2 (VCA) DECAY
EG TRIG MIX
This blends between triggers from SEQ1 and SEQ2 which are sent to EG1 and
EG2. Fully counterclockwise, triggers from SEQ1 have a velocity of 100% and
triggers from SEQ2 are suppressed. Fully clockwise, triggers from SEQ1 are
suppressed and triggers from SEQ2 have a velocity of 100%. At 12 o'clock,
triggers from both SEQs are at equal levels.
EG1 DECAY
This sets the decay time for EG1. The envelope generator produces a percussive
envelope with no attack time and variable decay from around 10 milliseconds
to greater than five seconds.
EG2 (VCA) DECAY
This sets the decay time for EG2 which is internally patched to the VCW and
VCF VCAs. The envelope generator produces a percussive envelope with no
attack time and variable decay from around 10 milliseconds to greater than
five seconds.
TRIGGER
This manually triggers both EG1 and EG2.
RUN/STOP
This starts/stops SEQ1 and SEQ2. These sequencers do not reset when stopped/
started; they can be overridden via MIDI Start/Stop/Continue commands.
