MIXER SECTION
•
OSC1 VOL – Input level of OSC1 to the mixer.
•
OSC2 VOL – Input level of OSC2 to the mixer.
•
NOISE/EXT VOL – Input level of NOISE to the mixer. Plugging a signal to the EXT
INPUT jack overrides NOISE.
FILTER SECTION (VCF)
•
CUTOFF – Controls the cutoff frequency of the 24 dB / octave low-pass filter (VCF).
•
EMPHASIS – Adds emphasis at the cutoff frequency (resonance).
•
CONTOUR – Controls the max amount of filter contour generator affecting the filter.
•
KEY TRACK – Controls the amount of keyboard control voltage applied to the filter.
CONTOUR GENERATOR SECTION (ENVELOPES)
Progue has two Contour Generators (Envelopes): the top one controlling the filter and
the bottom one controlling the amplitude (VCA).
•
ATTACK – Attack time of generated envelope.
•
DECAY/RELEASE – Decay and Release time of generated envelope.
•
SUSTAIN – Sustain level of the generated envelope.
•
RELEASE – Three-position switch:
§
FAST – Static “fast” release time, “Decay/Release” potentiometer only sets the
decay time of the contour generator.
§
ON – The “Decay/Release” potentiometer sets both decay and release time.
§
OFF – Static instant release time, “Decay/Release” potentiometer only sets the
decay time of the contour generator.
•
GATE MODE – Three-position switch:
§
AUTO – Contour generators are triggered by the MOD LFO.
§
NORM – GATE or MIDI signal is needed for triggering the contour generators.
§
GATE SYNC – Same as above, and both OSC1 and OSC2 are synced to GATE.
MODULATION SECTION (LFO)
Progue has two Low-Frequency Oscillators (LFO): MOD LFO and PWM LFO.
•
OSC MOD – Controls the amount of modulation applied to OSC1 and OSC2.
•
VCF MOD – Controls the amount of modulation applied to the filter.
•
MOD SHAPE - Selects between Triangle / Square / Sample&Hold (Random).
•
MOD RATE – Controls the MOD LFO rate.
•
MW/AT DEST. – Sets the source and destination of the Midi controllable modulation.
Sources include MOD LFO triangle and square, and PWM LFO triangle. Destinations
include VCO, VCF, and BOTH. The modulation amount can only be accessed via Midi.
