SETTING DELAY TIME
To change the delay time source, hold the shift button and
press the tap stompswitch.
DELAY TIME SOURCES
Local Tap (Tap LED shines Red): When the user taps in a tap
time, it gets scaled by the ratio knob, and is saved with the
preset.
Global Tap (Tap LED shines Blue): When the user taps in Global
Tap, it sets the global tap time. This Global Tap propagates to
any other modes running with Global Tap. If you load a new
preset that has Global Tap, it will use this time. Each preset and
engine applies its own ratio setting to the global tap time
making it easy to sync delays at musical ratios.
Knob (Tap LED shines Green): Turning the knob adjusts the
delay time from 20ms to 1.2s (in most modes).
MULTI-TAP
Multi-tap modes allow you to tap in a sequence of up to 5 taps.
The tap LED will blink the sequence tapped, with the ratio
applied, and then pause for 2 seconds. Multi-tap modes have
their own global tap.
USING DUAL DELAY ENGINES
The Echosystem has two engines which can each run any
mode. You can route these engines in parallel, serial, or split
left/right.
When using dual engines, two mode LEDs light up. The bright
one is the mode whose controls are active. Press down on the
mode knob to toggle which mode is active.
SYNC DELAY TIMES BET WEEN ENGINES
Hold the tap stomp and press the engines button, and the
delay time from the bright mode will be sent to the dimmed
mode. Note: The delay time sent to the other mode is the time
you tapped (pre-ratio) and the dimmed mode will apply its
ratio to that tapped time. This makes it easy to have the modes
in sync at different ratios. Both modes must be set to tap
tempo to sync delay times.
SOLO AN ENGINE
When getting sounds while using dual engines, it can help to
mute the dimmed mode temporarily. Hold the shift button and
press down on the mode knob to solo the active mode. The
active mode LED will blink while solo’d. To return to normal
operation press the mode knob again.
PRESETS
The Echosystem has two types of preset systems: the scrolling
preset system, and the bank preset system. Read about each
preset system to find which one will work best for you. Select
which preset system to use in Advanced Configuration.
SCROLLING PRESET SYSTEM
Preset Organization
In Advanced Configuration you can select the number of
presets you wish to use. The presets are represented by a
series of five LEDs located just below the knobs. Press the scroll
stompswitch to scroll through the presets. The preset LEDs will
blink. When cycling through the presets, after every five
presets, the preset LED colors will change to another color to
indicate you're in the next bank and will start counting again
from left to right.
When cycling through the presets, after your final preset, all
the preset LEDs will flash very quickly. This represents the
manual preset. If you recall this preset, the Echosystem will get
its settings from the current knob positions. In the manual
preset, no preset LEDs are lit.
You can scroll backwards through the presets by pressing the
tap and scroll stompswitches simultaneously.
Saving a Preset
To save the current settings to a preset, press the scroll
stompswitch until you reach the preset location where you
want to write. While the lights are flashing, hold down the shift
button and press the scroll stompswitch. Your preset is now
saved.
Recalling a Preset
To recall a preset simply press the scroll stompswitch until the
preset you’d like to recall is flashing, then press the tap
stompswitch to load the preset. The presets LEDs should now
be solid and bright.
What settings are saved in my preset?
If you change the position of a knob or switch after a preset is
loaded, the preset LEDs will dim to indicate that the preset has
been modified, but not saved. If you move the knob or switch
back to the position it was in when the preset was saved, the
preset’s LED indicators will brighten again. This lets you find the
positions of all the knobs and switches when the preset was
saved.
BANK PRESET SYSTEM
Preset Organization
In Advanced Configuration you'll select the number of banks
you wish to use. The preset LEDs display which bank is selected
by changing color. The middle and right stompswitches each
represent a preset. So there are two presets per bank.
Recalling a Preset and Bypassing the Pedal
To recall a preset, press on the middle or right stompswitch.
The light above that stompswitch and the bypass LED will
illuminate. To load another preset, simply press the other
stompswitch. To bypass the pedal, press the stompswitch
corresponding to the active preset, and the bypass LED will
turn off. The pedal is now bypassed.
Changing Banks
To bank up, press the right and middle stompswitches
simultaneously. To bank down, press the left and middle
stompswitches simultaneously. The LEDs will flash indicating
the target bank, then you can press any of the stompswitches
to load a preset within that bank.
Saving a Preset
To save a preset, set the knobs to the sound you would like to
save, then navigate to the target bank. While the lights are
blinking, press and hold the shift button and select the target
preset location by pressing the corresponding stompswitch.
BANK PRESET SYSTEM - WITH EXTERNAL TAP
If you'd like three presets per bank, you can use an external tap
switch. By setting the pedal's Advanced Configuration to bank
presets and the control port setting to either normally-open tap
or normally-closed tap you will get 3 presets available per bank.
(Changing the delay time source is done by holding the shift
button and pressing the external tap in this configuration.)
CONTROL PORT
The control port jack allows the Echosystem to be controlled by
a multitude of devices. The pedal ships configured to accept an
expression pedal. Please see the Advanced Configuration
section on how to configure the control port for the device you
plan to use.
EXPRESSION PEDAL
Each parameter, with the exception of the mode knob, can be
controlled simultaneously via the expression pedal.
To control a parameter with the expression pedal, move the
parameter's knob to the desired heel setting, then hold down
the shift button and move the knob to the desired toe setting,
then release the shift button. Multiple parameters can be
assigned for expression pedal control simultaneously by
repeating this process for each parameter to be assigned. Each
parameter can be set with independent heel and toe settings.
To release a parameter from the expression pedal's control,
move the knob that controls that parameter.
Any expression pedal used with the Echosystem should have
the following pinout: tip to signal, ring to power, and sleeve to
ground.
CONTROL VOLTAGE (CV)
With CV control, the Echosystem responds to CV signals from 0
to 5 volts. Otherwise, the CV configuration works exactly like
the expression pedal configuration.
EXTERNAL TAP SWITCH
The Echosystem can be used with either a normally-open or a
normally-closed external switch. This switch operates like the
tap stompswitch, with the exception of loading presets.
MIDI
All the parameters of the Echosystem can be controlled via
control change messages. Its presets can be selected with
program change messages, and its tempo can be controlled
with MIDI clock messages.
To use MIDI with your Echosystem, you'll have to:
1.
2.
Connect the Empress Midibox (not included with the
Echosystem) using a ¼” patch cable to the control port. A
TRS cable is required to send MIDI out messages if you're
using the Echosystem to control other pedals.
Configure the pedal for MIDI control and set the MIDI
channel. See Advanced Configuration for instructions.
Choose a MIDI channel that won't conflict with other
devices in your MIDI rig.
Recalling a preset via MIDI (Program Change Messages)
You can activate a preset by sending a MIDI program change
message. For example, sending a program change message of
7 activates preset 7.
Midi with Preset Out
The Echosystem can send out MIDI program changes on the
ring of the control port jack whenever a preset is loaded on the
Echosystem. The Echosystem will send out these program
changes on the 4 channels above the Echosystem's current
MIDI channel.
For example, if the Echosystem is set to MIDI channel 5
and preset 3 is loaded, the Echosystem will send out
MIDI program change 3 on MIDI channels 6, 7, 8 & 9.
Midi Beat Clock
Modes that accept a tap tempo input will respond to MIDI
clock messages. MIDI clock specifies quarter notes, subdivided
into 24 MIDI messages. The Echosystem's delay time gets set to
a quarter note.
Midi Control Changes
The Echosystem can be controlled with MIDI control change
messages. Opposite is a table that shows which MIDI control
change number controls each Echosystem parameter.

The modes and sub-modes are
numbered starting from 0
(Digital = 0, Tape = 1, etc.) To
translate the modes and submode to a single number you
apply the following equation:
MIDI message value = (mode x
8) + sub-mode
Example: To load the 2nd tape
mode, you'd send a value of 9
with the CC message. (1x8) + 1.

until a value of zero is sent,
simulating releasing the
switch.
Sending a value of 0 causes the
engine to ignore MIDI clock
messages. Sending a value of
127 causes the engine to listen
for MIDI clock messages. (by
default, the pedal listens for
MIDI clock messages)
Additional MIDI Control Change Notes
- MIDI switching cannot be done while in Advanced
Configuration.
- the manual preset cannot be used while using the bank preset
system.
USING HARDWARE INSERT
External effects can be inserted into the delay line using
hardware insert. You’ll need to enable this mode in advanced
configuration. Then, connect as below:
In this configuration the unit operates in mono. Left/right
routing won't function as expected.
If using dual delays, the hardware insert goes on engine 0 (the
first delay when in series).
ADVANCED CONFIGURATION
The advanced configuration customizes how your pedal
operates. The options are listed in the table that follows.
Entering Advanced Configuration
While holding down the tap and bypass stompswitches, press
the shift button. All the preset LEDs will blink yellow twice to
confirm you're in.
While in Advanced Configuration
Each mode LED represents a different configuration item you
can change. Look up the item you'd like to change from the
table on the right, then turn the mode knob to select it.
Turn the delay time knob to modify the value of the advanced
configuration setting. The preset LEDs will illuminate to show
you the current value. For example, if the blue digital mode LED
is lit and the 2nd preset LED is lit, you've configured the pedal
for buffered bypass operation.
Exiting Advanced Configuration
Hold down tap and bypass stompswitches while in advanced
configuration. Preset LEDs will blink yellow twice and the pedal
will reboot.

FIRMWARE UPDATES
This pedal has firmware that can be updated with an SD card.
Performing A Firmware Update
1) download the firmware file off the website
www.empresseffects.com/echosystem-firmware
2) copy the file to the root directory of the SD card
(a high-capacity SD card that's been formatted FAT32)
3) insert the SD card then power on the pedal.
4) The preset LEDs should marquee yellow for a bit, then all
turn green when the update is complete.
5) remove SD card, cycle the pedal's power, and you're good!
SD Card Constraints
There should only be one partition on the SD card because the
pedal only looks at the first partition on the disk. SD card must
be V2 high speed. Nowadays this is the most common type.
Firmware Update Error Codes
The preset LEDs will blink to signal an error:
1. unusable card
2. V1 card
3. V2 standard card
4. unable to read disk
5. valid FAT volume not found on SD card.
FACTORY RESET
WARNING! This will overwrite your current presets and advanced
config settings and replace them with the factory presets and
default advanced config settings!
To restore the Echosystem to its factory settings, do the
following: while in the advanced configuration (see Entering
Advanced Configuration): press and release the stompswitches
in this order: Tap, Bypass, Tap, Bypass. Then the LEDs do a
dance. Now you can exit advanced configuration (see Exiting
Advanced Configuration).
POWERING THE ECHOSYSTEM
Go to www.empresseffects.com/power for a full list of
compatible power supplies.
Please Note: The Echosystem requires at least 300mA of
current to function properly. Any power supply rated at 9V DC,
supplying negative tip polarity (
of current should work.
) and at least 300mA
