character as the DEPTH knob is adjusted
barber: continuously rising or falling LFO. Direction is set via live

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.
ON
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.

Adjusts the LFO range. Higher settings
result in more dramatic phase and/or time
modulations as set by the VOICE knob.

Engages the 6-Stage phaser circuit,
independent of the 4-Stage phaser. RED
ON LED indicates that the 6-Stage phaser
is engaged. The LED pulses in time with

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.)

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

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.
