Knobs and Switches – 4-Stage Phaser Controls
SWEEP Selects the style of the 4-Stage phaser.
classic: traditional rising and falling LFO* voicings that change in character
as the DEPTH knob is adjusted barber: continuously rising or falling LFO.
Direction is set via live edit function (See page 10 for details.) env: touch
sensitive envelope phasing effect with range set by the SPEED knob and
sensitivity set by the DEPTH knob
SPEED Adjusts the LFO rate.
MIX Adjusts the balance of the dry signal and the phase-shifted signal from
mild phasing at min to 100% wet at max. Strongest phasing effect occurs with
knob set at 12 o’clock (50/50 mix).
DEPTH Adjusts the LFO range. A deeper phasing effect is achieved as the knob
is turned clockwise.

Engages the 4-Stage phaser circuit, independent of the 6-Stage phaser. RED ON
LED indicates that the 4-Stage phaser is engaged. The LED pulses in time with
the selected SPEED when engaged.
NOTE: *An LFO is a low frequency oscillator. It is used to modulate the
filters that create the phasing effect.

NOTE: When both the 4-Stage phaser and the 6-Stage phaser are disengaged, the
bypass is either Buffered Bypass or True Bypass depending on the selected
mode. (See page 14 for details.)

change color to indicate the current status as the knob is turned.
VOICE knob selections:
Series: GREEN (default) – Output of the 6-Stage phaser feeds into the 4-Stage
phaser when both sides are engaged.
Parallel: BLUE – Output of both the 4-Stage and 6-Stage phasers are mixed to
the outputs while maintaining stereo independence of the LEFT and RIGHT
signals.
Split: RED – Sets both the 4-Stage and 6-Stage phasers as mono effects that
are sent to separate outputs. Output of the 4-Stage phaser goes to OUT L, and
output of the 6-Stage phaser goes to OUT R. (For stereo output connections
only.)

MIDI Functionality Configuring Zelzah to Use MIDI
Using MIDI unlocks a set of tools that can be used to load any of Zelzah’s 300
preset locations using a suitable MIDI controller or interface connected to
Zelzah’s EXP/MIDI jack. This requires a Strymon MIDI EXP cable or a MIDI
controller/interface, such as Strymon Conduit, with at least one quarter-inch
output. When using a Strymon MIDI EXP Cable, the MIDI OUT mode must be set to
OFF. (See page 27 for more info.)

MIDI PROGRAM CHANGES
Zelzah contains 300 preset locations, numbered sequentially from 0-299.
Because MIDI Program Change messages have a maximum number of 128 (0-127) the
presets are grouped into three MIDI patch banks.
MIDI BANK 0 = PRESETS 0-127 MIDI BANK 1 = PRESETS 128-255 MIDI BANK 2 =
PRESETS 256-299
0 Favorite setting (accessible via MiniSwitch) (See page 19 for details.)
1 MultiSwitch Plus footswitch 1 2 MultiSwitch Plus footswitch 2 3 MultiSwitch
Plus footswitch 3 127 Manual mode (“knobs”)
Zelzah always powers up in MIDI Patch Bank 0, so if you plan to stay within
the first 127 presets, simply send a standard MIDI Program Change message to
load a preset. If you will be using MIDI Banks 1 and/or 2, it is advisable to
send a standard MIDI Bank Change message (MIDI CC# 0 with a value equal to the
MIDI Bank#) before each MIDI Program Change. Selecting bank 0, patch 127 will
put Zelzah into Manual mode. In this mode, the pedal will be set to the
current knob and switch settings. No preset data can be stored at this preset
location.
