84 DeepMind 12 User Manual

Flanger

The Flanger emulates the phase-shifting sound (comb-fi ltering) originally
created by applying pressure against the fl ange of the reel on a tape recorder.
This eff ect creates a unique "wobbly" sound that is quite dramatic when used on
vocals and instruments.
The controls of this eff ect are nearly identical to the Chorus eff ect block.
Additionally, the FEEDBACK can be adjusted with positive and negative amounts
and also band-limited with the FEED HC (high-cut) and FEED LC (low-cut) knobs.

Phaser

A Stereo Phaser, or phase shifter, applies multiple STAGES of modulated fi lters to
the input signal to create a "notch" in the frequency response, and then applies
a MIX with the original for a "swirling" eff ect. Use the Stereo Phaser to add a
"spaced-out" sound to vocal or instrument tracks.
SPEED adjusts the LFO rate and DEPTH sets the LFO modulation depth. The BASE
knob adjusts the frequency range of the modulated fi lters. The resonance is
adjusted with the RES knob. The WAVE knob shapes the symmetry of the LFO
waveform and PHASE dials in an LFO phase diff erence between the left and right
channel. The modulation source can also be the signal envelope, which produces
vowel-like opening and closing tones. The ENV knob adjusts how much this eff ect
takes place (positive and negative modulation is possible), and the ATTACK, HOLD
and RELEASE knobs all tailor the response of this feature.

Mood Filter

The Mood Filter uses an LFO generator and an auto-envelope generator to control
a VCF (voltage-controlled fi lter), as well as a side chain function where the
channel B signal controls the envelope of channel A.
This fi lter can be modulated with the signal's envelope using the ENV MOD
(with positive and negative amounts), ATTACK and RELEASE knobs, or the
LFO can modulate the fi lter. The WAVE knob selects between 7 diff erent wave
forms – triangular, sine, saw plus, saw minus, ramp, square, and random.
The PHASE can be off set by up to 180 degrees. The SPEED knob adjusts the rate
of the LFO and the DEPTH adjusts the amount of LFO modulation. Adjust the
resonance of the fi lter until self-oscillation with the RESO(nance) knob.
BASE adjusts the range of the fi lter from 20 Hz to 15 kHz. The MODE switch
selects between low pass (LP), high-pass (HP), band-pass (BP) and Notch. Use the
MIX knob to blend the eff ected signal with the dry sound. With the 4 POLE switch
engaged, there will be a steeper slope than the OFF (2 pole) setting. The DRIVE
knob adjusts the level and can also introduce an overdrive eff ect (as with real
analog fi lters) if pushed hard.

Stereo / Dual Pitch

Pitch shifting is often used in two diff erent ways. One is to set the Mix knob lower
and only use the Cent knob to make a small off set in pitch between the wet and
dry tones. This results in a "voice doubling" eff ect that thickens the overall sound
in a more subtle way. The extreme use of the eff ect is to turn the Mix knob fully
clockwise so the entire signal is eff ected. This way, the signal can be shifted into
other keys up to an octave above or below the original. When used on a voice,
this results in a "chipmunk" sound or a low Darth Vader eff ect.
When the SEMI and CENT knobs are set at 12:00, the pitch is not altered.
Making adjustments by semitone will have a very pronounced eff ect,
whereas changes to the CENT knob will be very minor. The DELAY knob creates
a time diff erence between the wet and dry sound. The LO and HI CUT knobs
allow the eff ected signal to be band-limited. The Dual Pitch eff ect allows
the left and right channels to be adjusted independently, and allows GAIN
compensation and panning of the two channels.

Rotary Speaker

Rotary Speaker emulates the sound of a Leslie rotating speaker. The Rotary
Speaker provides more fl exibility than its electromechanical counterpart, and can
be used with a variety of instruments, and even vocals, to create a whirling,
psychedelic eff ect.
The LO SPEED and HI SPEED knobs adjust the rotational speed of the
SLOW and FAST Speed selection, and can be toggled with the FAST switch.
The ACCEL(eration) knob adjusts how quickly the speed increases and
decreases from the Slow mode to the Fast mode. The rotation eff ect can also
be disengaged with the STOP switch, which will stop the movement of the
speakers. DISTANCE adjusts the distance between the Rotary speakers and the
virtual microphone.
