Moog MINITUAR, User Manual

Page: 9 / 20

MODULATION is an important part in the crea-
tion of musically-expressive sounds. The Minitaur’s
MODULATION section provides an LFO with adjustable
RATE and AMOUNT controls for the oscillators
(VCO) and the Filter (VCF). The Low Frequency
Oscillator (LFO) is a signal used to move the pitch of VCOs and the Filter Cutoff
up and down automatically. A LFO can be used to simulate vibrato, create
wobbling filter sweeps, or make interesting synthesizer sounds.
MODULATION (MOD)
PANEL CONTROLS FOR MODULATION
LFO RATE (CC# 3):
Sets the frequency of LFO Modulation. The range is from 0.01Hz to 100Hz.
VCO LFO AMOUNT
(CC# 13):
Sets the maximum amount the LFO moves the VCOs pitch up and down,
up to +/- 1 octave. Modulation affects both Oscillators. Amounts above MIDI
Note 72 are clipped. If using a MIDI controller, the Mod Wheel (CC# 1) is
used to fade the LFO Pitch Modulation in and out.
VCF LFO AMOUNT (CC# 12):
Sets the maximum amount the LFO moves the Filter Cutoff up and down,
up to +/- 5 octaves. Amounts above 20KHz or below 20 Hz are clipped. If
using a MIDI controller, the Mod Wheel (CC# 1) is used to fade the LFO
Filter Modulation in and out.
MIDI ACCESSIBLE CONTROL
LFO MIDI SYNC ON/OFF
(CC# 87):
Enables or Disables the ability of the Minitaur’s LFO to sync to MIDI
Clock messages.
Default = ON.
LFO SYNC CLOCK DIVISION (CC# 86):
Selects the LFO Clock division when the LFO Sync Source is set to MIDI
Clock. LFO Division Settings are listed on page 24. The LFO RATE control
can also act as a Clock Divider.
Default = 1/4.
LFO KEY TRIGGER (CC# 82):
Re-triggers the start of the LFO cycle when a NOTE ON message or KB GATE
Control Voltage is received.
Default = OFF.
NOTE : When the Minitaur powers up, the settings on the VCO LFO AMOUNT
and VCF LFO AMOUNT controls have a direct effect on the VCO and VCF. This
behavior continues until the Minitaur receives a MIDI Mod Wheel command,
from which point the Mod Wheel takes master control of the LFO modulation
amount set by the Amount controls.

note is released, the EG moves back to zero at the rate set by this control.
The time ranges from 1 msec to 30 seconds. The Release segment of the
Envelope is determined by the state of the RELEASE switch (ON/OFF).
AMPLIFIER SUSTAIN
(CC# 30):
Sets the Amplifier EG level after the Decay and before the Release portion.
A note must be held longer than both the Attack and Decay time to reach
the Sustain level. The level is adjustable from 0 to 100%.
MIDI ACCESSIBLE CONTROL
OUTPUT (VCA) VELOCITY SENSITIVITY (CC# 90):
Sets the amount of MIDI Note velocity to the Amplifier.
Default = 64 (50%).
EXTERNAL CV CONTROL
The GATE jack on the back panel is a trigger input that accepts a +5V Gate
signal. Applying a Gate signal causes both Envelopes (Amplifier and Filter)
to trigger simultaneously.
NOTE: When a Gate signal is applied, it overrides
triggering via MIDI. You will still be able to control the Oscillator pitch and
Modulation amounts from a MIDI controller, but the envelopes will not
retrigger until the Gate trigger is removed.
The RELEASE switch enables or disables the Release segment of
both Envelope Generators. When enabled, the Envelope Release
time is the same as the Envelope Decay time, and the DECAY
control adjusts the time for both segments. When disabled, the
Release segment does not occur and the Envelope stops abruptly in response
to a “Note Off” message (or when the Gate CV goes to zero).
RELEASE
PANEL CONTROL FOR RELEASE
RELEASE Switch (CC# 72):
Enables/Disables the Release function for both Envelope Generators.
RELEASE is enabled when the switch LED is ON.
