Step 2: Controls
(EN)
OSCILLATOR SECTION VCO
(VOLTAGE CONTROLLED
OSCILLATOR)
(1) and (3) OSC TUNE - Adjusts the
frequency of oscillators.
(2) OSC MIX - Adjusts the blend between
oscillator 1 and 2.
(4) and (5) OSC SHAPE - Adjusts
the shape of the oscillator. Can be
configured to switch between fixed
waveforms or to blend continuously
between adjacent waveforms.
(6) and (7) OSC RANGE - Adjusts the
pipe length of oscillators between
32/16/8. +/-10 octave mode enabled
when all 3 LEDs are on.
(8) OSC SYNC - OSC 2 syncs to
OSC 1 period.
(9) PARAPHONIC - Allows the two
oscillators to be independently
pitched when more than one MIDI
note is played. If only one note is
received, both oscillators will play the
same pitch.
(10) and (11) PULSE WIDTH (PW) - Sets
the pulse width of oscillator square /
tone mod waveforms.
VCF SECTION (VOLTAGE
CONTROLLED FILTER)
(12) FREQ - Adjusts the cutoff frequency
of the VCF.
(13) MODE - Selects the filter type.
Choose between High Pass Filter
(
), Band Pass Filter (
) and Low
Pass Filter (
).
(14) RESO - Adjusts the resonance of
the filter.
(15) KEY TRK - Applies keyboard tracking
to the VCF.
(16) MOD DEPTH - Sets the depth of filter
modulation from the FREQ MOD input.
(17) ENV DEPTH - Sets the depth of filter
modulation from ENVELOPE 2.
LFO SECTION (LOW
FREQUENCY OSCILLATOR)
(18) SHAPE - Adjusts the shape of the LFO.
(19) RATE - Adjusts the frequency of
the LFO.
(20) KEY SYNC - Re-trigger the LFO when a
midi note is received.
NOISE & VCA BIAS
(21) NOISE LEVEL - Adjusts the amount of
white noise injected into the filter.
(22) VCA BIAS - Opens or closes the VCA.
DELAY SECTION
(23) TIME - Controls the rate of the delay.
(24) REPEATS - Controls the number
of repeats.
(25) MIX - Adjusts the wet/dry mix of
the Delay.
OVERDRIVE SECTION
(26) DRIVE - Sets the amount of overdrive.
(27) TONE - Changes the timbre of the
overdriven sound.
(28) LEVEL - Controls the volume of the
overdrive output. When fully off you
may hear no audio at the output.
ENVELOPE SECTION
ENVELOPE 1
Envelope 1 is routed to the VCA CV by
default.
(29) A [ATTACK] - Controls the attack time
of the envelope.
(30) D [DECAY] - Controls the decay time
of the envelope.
(31) S [SUSTAIN] - Controls the sustain
level of the envelope.
(32) R [RELEASE] - Controls the release
time of the envelope.
ENVELOPE 2
Envelope 2 is routed to the VCF filter
cutoff via ENV DEPTH control by default.
See 17. ADSR knobs 33-36 function the
same as 29-32.
OUTPUT SECTION
(37) VOLUME - Controls the main
output level.
(38) MIDI IN - Accepts incoming MIDI data
from the selected midi channel.
SAMPLE & HOLD CLOCK
Generates a random pattern based on the
sample & hold clock.
(39) RATE - Controls the rate of the
SAMPLE AND HOLD clock.
(40) GLIDE - Sets the rate of change
between sample values.
SLEW RATE LIMITER
(41) SLEW - limits the rate of change of the
input signal.
(42) PORTA TIME - Controls the rate of
change between midi notes.
ATTENUATOR SECTION
(43) ATTENUATOR 1 - Used to reduce
the amplitude of the input signal.
ATT1 can be controlled by a control
voltage. See 58.
(44) ATTENUATOR 2 - Reduces the
amplitude of a signal.
