Introduction
1
The System80 880 is an analog drum machine for the
Eurorack modular synthesizer format. Its drum voice
circuits are based on the TR-808, the classic drum
machine made by Roland Corporation between 1980
and 1983. Wherever possible, the 880 uses the exact
same semiconductors specified in the original circuits.
The sound very closely matches the sound and character of the two vintage TR-808s that were used as
references during the 880's design. Variation in
component tolerances as well as component aging
may contribute to some perceptable differences in
sound between the 880 and a vintage TR-808.
However, the same holds true for sound comparisons
between original TR-808s and other 808 clones.
The 880 features all 16 of the original TR-808's analog
drum voices with one important difference: the five
switchable voices are controlled with electronic rather
than mechanical switches. The automatic switching
between the paired drum voices allows them to be
played on differ ent steps of the same pattern. For
example, the Low Tom can be played on Step 1 and
Step 3 of a pattern and the Low Conga can be played
on Step 2 of the same pattern; the sequencer will
automatically switch between the sounds as the
pattern plays.
The 880's sequencer features a familiar interface that
allows for Rhythm Pattern creation using programmed
or real-time step entry. Manual Mode can be used for
arrangement and improvisation during live
performance. There is also a Rhythm Compose mode
that allows patterns to be chained together into longer
compositions.
The sequencer has been updated with 12 banks of 16
Rhythm Patterns, shuffle, mutes, performance rolls, a
pair of fully assignable trigger outputs, and multiple
options for syncing to external devices.
The Eurorack modular synthesizer format invites
experimentation and improvisation. The 880 features
11 indivdual instrument outputs for separate mixing
and processing of the sounds, either within a Eurorack
system or through other devices, such as filters,
reverb, compression, distortion, digital multi-effects,
etc.
A planned Trigger Expander module will allow the
880's drum voices to be triggered externally.

The 880 is a 60 HP Eurorack module. It must be
installed correctly in a Eurorack case and supplied with
Eurorack standard power. Use the supplied screws
and washers to install the 880 in your Eurorack case.
Set Trigger 2
Level
Connecting Power
The 880 uses a standard Eurorack non-shrouded/nonkeyed power connector. The cutout in the back panel,
however, does provide a keyed opening to ensure the
cable is connected in the correct orientation (Fig. 2).
A standard 10 pin Eurorack power cable is supplied.
The red stripe on the power cable indicates the position of the −12V conductor. When connecting the
power cable ensure that the red stripe side of the cable
is aligned with the thick line next to the power header
on the back panel. Connect the 10 pin connector to the
880's power header and connect the 16 pin connector
to your system's power bus board.
The 880 is designed to withstand brief conditions of
reverse power, but prolonged connection to reverse
polarity may damage the protection diodes and require
module servicing.
Fig. 2 Eurorack power header, back panel
CAUTION: Do not apply power to the 880 when it is
not securely installed in a Eurorack case.

trigger level may be required to trigger the envelopes
and clock inputs of some vintage equipment (eg. ARP
2600, Roland System 100/100M, etc.).
A jumper connector on the back of the 880 is used to
set the Trigger 2 level (Fig. 3). It is set to 5 Volts at the
factory. To change the Trigger 2 level to 12 Volts,
remove the jumper with a pair of tweezers or needlenose pliers and move it to the 12 Volt setting. Ensure
there is no power applied to the 880 when changing
the jumper setting.
DIN Socket Ground

employs an optocoupler to isolate MIDI devices from
one another. The DIN Sync standard, however,
requires a ground connection between devices. To
ensure compatibilty with legacy DIN Sync devices, pin
2 is grounded via a jumper on the back of the 880.
Grounding pin 2 of a MIDI IN socket does not conform
to the MIDI electrical standard. If a ground loop is
introduced by MIDI cabling this may be resolved by
changing the jumper to disconnect or 'lift' the pin 2
ground connection (Fig. 4).

Power Supply
Ensure that your power supply has sufficient overhead
to handle the current drawn by all of the Eurorack
modules connected to it. When its power supply is
overloaded the 880 will function erratically or not at all.
It is strongly recommended that a professional, high
quality Eurorack power supply be used with the 880.
Do-It-Yourself (DIY) power supplies and unfiltered 'offthe-shelf' switching power modules may result in
unwanted noise and performance issues.

Master Output
All of the 880's instruments are summed together at
the MASTER OUT jack. The level of each drum voice
in the master out mix is controlled by each instrument's
LEVEL control. When auditioning and recording from
the master output adjust the instrument LEVEL controls to obtain the desired balance of each instrument
in the mix. Use the MASTER VOLUME control to
achieve the desired output level into your monitoring
and/or recording device.
NOTE: The 880 is a clone of a vintage analog design.
Yo u ma y fi nd th e no i se f lo o r hi gh e r co mp a re d to o t he r
contemporary electronic instruments, especially on the
master output.
Instrument Outputs
There are five instrument pairs that each share an
output (LC/LT, MC/MT, HC/HT, RS/CL, and CP/MA).
The LEVEL control for these instrument pairs affects
the level of both instruments.
The 880 has 11 individual audio outputs. Connecting
a jack to an instrument's individual output removes that
instrument from the summed MASTER OUT signal.
An instrument's level at its output jack is determined
only by its LEVEL control and is not affected by the
MASTER VOLUME control.

sequencers. See the Quick Tips section on Page 5 for
details on how to assign any of the instrument triggers
to either of the Trigger Outputs.
Each trigger signal is a positive 5 Volt, 20 millisecond
(ms) pulse suitable for activating most Trigger and
Gate inputs on other equipment.
Sync In
The SYNC IN jack is used to slave the 880's sequencer to an external analog clock pulse. When set as
a SYNC IN slave (see Synchronization, Page 13), the
sequencer will respond to the rising edge of a 5 Volt
clock pulse received on the SYNC IN jack at a rate of
2 Pulses Per Quarter Note (PPQN).
MIDI/Sync
The MIDI/SYNC jack is a multi-function DIN connector
used to receive MIDI data and send, or receive DIN
Sync (Sync24) data. Its function is dependent on the
Synchronization Mode (see Synchronization, Page
12).

The PLAY mode allows you to play any of the 12
Rhythm Tracks stored in memory. The Rhythm Tracks
are selected using the INSTRUMENT/TRACK buttons.
The MODE selector control is located in the upper left
corner of the control panel and is used to select
different operations for both programming and playing
the instrument. Pressing the MODE key cycles through
each of the six modes: PATTERN CLEAR,
1st PART, 2nd PART, MANUAL PLAY, PLAY, and
COMPOSE. Holding the SHIFT-WRITE/NEXT key
while pressing the MODE key reverses the direction of
the selection cycle.
The PATTERN CLEAR mode is used to clear patterns from memory so that Rhythm Patterns can be
reprogrammed. The red CLEAR button is used to
activate the CLEAR function while in PATTERN
CLEAR mode. The 1st PART mode is used to program the first section of a pattern. Patterns with 16 or
fewer steps can be programmed using just the 1st part
of the pattern programming mode. To create patterns
of up to 32 steps, the 2nd PART mode is used. Patterns are initialized to 16 steps for the 1st part and 0
steps for the 2nd part. The red CLEAR button is used
in combination with the step switches to determine the
number of steps in a pattern. A combination of different
pattern lengths and PRE-SCALE settings allows different time signatures to be achieved.
The MANUAL PLAY mode is a performance mode
that allows you to play any of the Rhythm Patterns
stored in memory. Additionally, it offers automatic
switching for intros and fills. Shuffle and instrument
rolls can be used in MANUAL PLAY mode to further
improvise during performance.
Holding the SHIFT-WRITE/NEXT key while pressing
the AUTO FILL IN button changes the context of the
control to set the SYNC MODE. The SYNC MODE
cycles through INTERNAL CLOCK, MIDI IN, DIN
SYNC2 4 OU T, DIN SYNC 24 IN, an d SYN C IN mod es.
The AUTO FILL IN selector is used to insert Fill In
Rhythm Patterns while playing in MANUAL PLAY
mode. Pressing the AUTO FILL IN selector button
cycles through the six different fill options. The first fill
option is MANUAL which allows Fill In Rhythms to be
inserted manually by pressing the TAP button. Automatic insertion of the Fill In Rhythm is accomplished
with any of the remaining five options: 16, 12, 8, 4 and
2. Automatic insertion occurs every 16th measure,
every 12th measure, every 8th measure, etc.
The Tempo Control sets the tempo of the internal
sequencer. The internal sequencer has a tempo range
of 30 beats per minute (BPM) to 290 BPM.
When the sequencer is stopped the currently selected
pattern's LED will blink in time with the tempo.
When the 880 is slaved to an external clock, the

There are 12 Instrument/Track selector buttons. When
programming Rhythm Patterns these buttons are used
to select a drum voice or Accent to program. From the
left the drum voices are AC (ACCENT), BD (BASS
DRUM), SD (SNARE DRUM), LT/LC (LOW TOM or
LOW CON GA), MT/MC ( MID TOM or MID CONGA ),
HT/HC (HI TOM or HI CONGA), RS/CL (RIM SHOT
or CLAVES), CP/MA (HANDCLAP or MARACAS), CB
(COWBELL), CY (CYMBAL), OH (OPEN HIHAT), and
CH (CLOSED HIHAT). When two options are available, you can press the Instrument button a second
time to toggle between the two available instruments.
Drum voices with two instruments can be programmed
independently on different steps of the same pattern.
The drum voice will automatically switch between
instruments on each step.
Holding the SHIFT-WRITE/NEXT key while pressing
an instrument will toggle its MUTE function. The Instrument/Track selectors are also used to select the 12
memories available for composing Rhythm Tracks in
COMPOSE mode and playing any individual Rhythm
Tr ac k i n P L AY mo d e.
The COMPOSE mode allows any of the Rhythm
Patterns stored in memory to be linked together into a
composition called a Rhythm Track. Each of the 12
Rhythm Tracks can contain a unique sequence of up
to 64 patterns. The Rhythm Track memories can be
cleared using the red CLEAR button. Programming
the sequence of Rhythm Patterns is accomplished
with the STEP buttons and the SHIFT-WRITE/NEXT
key.
Voice Controls
7
Each drum voice has a LEVEL control at the top of
each group of instrument controls. The LEVEL control
is used to control the level of the drum voice in the
MASTER OUTPUT mix. RIM SHOT/CLAVES, HAND
CLAP/MARACAS, COWBELL, and CLOSED HIHAT
only have a LEVEL control, whereas the other drum
voices have additional controls for adjusting the sound
of the instrument.
The ACCENT LEVEL control sets the amount of
emphasis given to accented steps in a pattern.
Accented steps give emphasis to any drum voices
that are programmed on the same step.
Step Buttons
The STEP buttons have different functions depending
on what mode the 880 is in and whether or not the
sequencer is running.
In Rhythm Pattern Programming modes (CLEAR, 1st
PAR T, 2n d PART ) th e ST EP b ut to ns ar e us ed t o
select a pattern to clear, play or edit. While the pattern
is playing the STEP buttons are used to program the
steps on which the currently selected drum voice will
play. In combination with the red CLEAR button, the
STEP buttons can be used to set the length of a
Rhythm Pattern.
In MANUAL PLAY mode the first 12 STEP buttons
are used to select one of the 12 BASIC RHYTHMs.
The last 4 STEP buttons are used to select one of the
4 INTRO/FILL INs. When the START/STOP button is
pressed the selected BASIC RHYTHM pattern will
begin to play unless the TAP button is used to
changed the priority to the selected INTRO/FILL IN
pattern. The priority between the BASIC RHYTHM
and INTRO/FILL IN pattern is indicated by their LEDs

While holding the SHIFT-WRITE/NEXT key, the
STEP buttons are used to select different SHUFFLE
amounts and ROLL modes.
In combination with the ALT key STEP buttons are
also used to select one of 12 seperate banks of
Rhythm Patterns.

BASIC VARIATION button to return to variation B.
A solid LED indicates the current variation playing and
a flashing LED indicates the variation that is waiting to
play once the current measure has finished.
The IF/VAR button is used to select the variation
mode for the INTRO/FILL IN patterns used in
MANUAL mode. Like the BASIC VARIATION
BUTTON it toggles between variation A and variation
B modes. When a INTRO/FILL IN pattern is playing
its variation MODE is indicated by the BASIC
VAR IAT ION L EDs .
In other modes, the IF/VAR button serves as an ALT
key, sometimes in combination with the SHIFTWRITE/NEXT key to access alternative functions.
The SHIFT-WRITE/NEXT key is used to access
alternative functions of the other buttons/keys on the
880's front panel. It can be used to MUTE drum
voices, assign the trigger outputs, change SHUFFLE
and ROLL settings, and SYNC behaviour, set the
PRE-SCALE and activate the ALT functions in combination with the IF/VAR button.
In COMPOSE mode, the SHIFT/WRITE key is used
to advance to the next pattern when creating or editing
Rhythm Tracks.
Starts or stops the internal pattern sequencer. Input

source.
In MANUAL PLAY Mode the TAP button is used for
manual insertion of INTROs and FILL INs. It is also
used to manually enter trigger steps for drum voices
during Rhythm Pattern programming. In PLAY and
COMPOSE Modes it can be used to display the
current measure of a Rhythm Track.
Controls the overall output volume of the summed
drum voices available a the MASTER OUT jack.
The BASIC VARIATION button is used to toggle
between the two variation modes, A and B. Each
Rhythm Pattern consists of two variation modes of
one measure each that can be played independently

simply press the button for the step you wish to edit to
We will now program a Rhythm Pattern using both the
1st and 2nd Parts to create a 32 step pattern. With the
sequencer stopped, select the desired pattern number.
Ensure the BASIC VARIATION is set to A, clear the
pattern and set the mode to 1st PART. Start the sequencer and program a Rhythm Pattern using the instrument selector buttons and the step switches. When
you are finished programming the 1st PART, set the
mode to 2nd PART. The sequencer will continue to
play the 1st Part because the cleared pattern has only
16 steps. While pressing and holding the CLEAR button select step #16. The 1st PART will now play and
then the step LEDs will blink while the 2nd PART plays.
Notice that the 1st PART and 2nd PART LEDs next to
the START/STOP button light to indicate which part is
currently playing. Program a pattern into the 2nd
PAR T to c om pl et e y ou r 32 s te p pa tt er n.
Alternatively, it is possible to layer the steps program-
med into the 2nd PART onto the 1st PART. When lay-
ered, the steps in the 2nd PART will be triggered
inbetween the steps of the 1st PART. This layering
mode is active only when the 2nd PART is set to 0
steps. Simply clear a pattern, program the 1st PART,
set the mode to the 2nd PART and progam a layer that
will play inbetween the steps of the 1st PART. In layering mode, the sequencer LEDs will not blink while the
2nd PART is edited.
The 2nd PART can be toggled between a laye r and an
extension of the 1st PART. To extend the 1st PART
with the 2nd PART, press and hold the CLEAR button
and select the desired pattern length using STEP
buttons #1 to #16. To activate layering mode again,
press and hold the CLEAR but-ton and press step #1
twice. This will reset the 2nd PART to 0 steps and
clear any steps that were programmed in the 2nd
PAR T.
The scale bars on the panel above the STEP buttons
indicate the PRE SCALE. Changing the PRE SCALE
changes the number of internal clock pulses that are
counted between steps. Different PRE SCALE settings in combination with different pattern lengths allow
the creation of a variety of different time signatures. By
default, patterns are cleared to PRE SCALE 3 and 16
steps (4/4 time).
The PRE SCALE can be changed while editing the
1st or 2nd PART and the changes are saved in
memory with the current pattern.

The 880 has a shuffle feature that alters the timing of
the odd steps in a Rhythm Pattern. Six levels of shuffle
are available. While the sequencer is running, hold
down the SHIFT-WRITE/NEXT key and select the
SHUFFLE AMOUNT using the first 6 STEP buttons.
Step #1 indicates no shuffle and steps #2 to #6 apply
increasing amounts of shuffle. In Rhythm Pattern

remain solid.
Press the START/STOP button. The sequencer will
begin to play the selected BASIC RHYTHM pattern.
While the sequencer is playing, select a new BASIC
RHYTHM pattern. When the current pattern finishes
playing the new pattern will start to play. If you wish to
change the current Pattern Bank, press and hold the
SHIFT-WRITE/NEXT key and the ALT key and select
one of the 12 Pattern Banks using the STEP buttons.
NOTE: MANUAL PLAY mode is the only mode where
the SHIFT-WRITE/NEXT key needs to be used in
combination with the ALT key to change the Pattern
Bank.
The BASIC VARIATION button can be used to select
the desired rhythm variation, A or B. Hold the SHIFTWRITE/NEXT key and press the BASIC VARIATION

followed by the selected BASIC RHYTHM pattern.
With the sequencer stopped, press the TAP button.
The selected BASIC RHYTHM LED will become solid
and the selected INTRO/FILL IN LED will flash. This
indicates that the Intro pattern is active and will play
before the BASIC RHYTHM pattern when the
sequencer is started. To cancel the Intro function,
press the TAP button again. The selected BASIC
RHYTHM LED will begin flashing and the INTRO/FILL
IN LED will remain solid.
A Fill In Rhythm Pattern can be inserted between the
BASIC RHYTHM pattern manually or at a programmed number of measures. To manually insert a Fill In
rhythm, set the AUTO FILL IN selector to MAN and
start the sequencer. The currently selected BASIC
RHYTHM will begin to play. While the sequencer is
playing press the TAP button. The currently playing
BASIC RHYTHM will finish and the selected INTRO/
FILL IN pattern will play once. Pressing the TAP button
again before the Fill In pattern finishes will make it play
again.
If the BASIC VARIATION mode is set to alternate
between variation A and B then pressing the TAP
button will replace the next variation with the Fill In
rhythm pattern. For example, if variation A is playing
and the TAP button is pressed, then the Fill In will replace the queued B variation and return to the A
variation.

pressing and holding the SHIFT-WRITE/NEXT key and
then pressing the ALT key twice. This action will shorten
the Rhythm Track by one measure and the pattern
stored in the previous measure will begin playing.
Press and hold the TAP button to display the current
measure you are editing in the Rhythm Track. The
current measure is read by multiplying the PRE-SCALE
LED position by the STEP LED position to indicate from
1 × 1 = measure #1 to 4 × 16 = measure #64.
When you have finished chaining patterns into a
Rhythm Track press START/STOP to stop the sequencer. The Rhythm Track is complete and can now
be played back in PLAY mode or edited in COMPOSE
mode.
you can change the pattern using the STEP buttons or
change to a different pattern bank by pressing and
holding the ALT key and selecting a new pattern bank.
These changes to the current measure are automatically committed to memory.
The current measure can be deleted by pressing and
holding the SHIFT-WRITE/NEXT key and then pressing
Step #16 (DEL). The length of the Rhythm Track will be
reduced by one measure and the pattern stored in the
measure after the deleted measure will be moved to the
current measure. If you are editing the last measure of
the Rhythm Track, then the delete function simply
deletes the last measure.
A new measure can be inserted into the Rhythm Track
by pressing and holding the SHIFT-WRITE/NEXT key
and then pressing Step #15 (INS). The length of the
Rhythm Track will be extended by one measure. If you
are editing the last measure of the Rhythm Track then
the current pattern is simply appended to the end of the
Rhythm Track.
Rhythm Tracks can be edited in three different ways:
the current measure can be Changed, Deleted, or
Inserted.
In COMPOSE mode use the Instrument/Track
buttons to select the track you wish to edit. If a track
has been cleared then it needs to be created before it
can be edited (See Creating The Rhythm Track,
above). When selecting a track to edit, the track's first
pattern will load from memory and be displayed by the
Step LEDs.
Start the sequencer. The pattern programmed into the
Rhythm Track's first measure will begin playing. Press
the SHIFT-WRITE/NEXT key to advance to the next
measure. Continue to use the SHIFT-WRITE/NEXT
key to navigate to the measure you wish to edit. You
can go back to the previous measure by pressing and

Synchronization
The DIN socket is configurable as a MIDI Input, a DIN
Sync24 Output or a DIN Sync24 Input.
Internal Clock Mode
Sync Modes
The 880 has four main synchronization modes. The
fourth mode has two sub modes:
1. INTERNAL CLOCK Mode [MASTER]
2. MIDI IN Mode [SLAVE]
3. DIN SYNC24 OUT Mode [MASTER]
4. SYNC IN Mode [SLAVE]
i. DIN SYNC24 IN
ii. SYNC IN CLOCK
The fourth mode, SYNC IN Mode, has two sub
modes that slave the 880 to an external clock pulse:
either a Sync24 pulse on the DIN socket or a clock
input on the SYNC IN jack.
Holding down the SHIFT-WRITE/NEXT key while
pressing the AUTO FILL IN button cycles through the
Sync Modes.
Sync Modes 1 (INTERNAL CLOCK) and 3 (DIN
SYNC2 4 OU T) a re M ASTER cloc k mo des tha t us e
the 880's internal clock to derive the sequencer's
tempo. The TEMPO knob controls the rate of the
sequencer.
Sync Mode 2 (MIDI IN) and the two sub modes of
Mode 4 (SYNC IN) are SLAVE clock modes that
require an external clock signal derived from MIDI clock,
DIN SYNC24 clock, or a clock pulse on the SYNC IN
jack.
When the 880 is running as a MASTER, the SYNC
LED will glow red. When running as a SLAVE, the
SYNC LED will glo w or ange . I f th e 880 i s wait ing for an
external clock pulse, the SYNC LED will glow yellow.
NOTE: Like an original TR-808, the 880's user interface
is dependent on an active clock signal. In any of the
SLAVE modes the interface will appear to freeze if there
isn't an active clock signal on the selected clock input. If
you set the Sync Mode to one of the slave modes without a clock present simply set the mode back to
INTERNAL CLOCK to continue normal operation.
INTERNAL CLOCK mode is capable fo sending MIDI
out data on a planned TRIGGER/SYNC expander
module.
The 880 powers up in INTERNAL CLOCK Mode
[INT]. The sequencer uses the internal clock, which is
controlled by the TEMPO knob. Clock signals on the
DIN socket and SYNC IN jack are ignored.
MIDI In Mode
When in MIDI IN Mode the DIN socket is configured
as a MIDI input. The 880 will respond to MIDI Start,
Stop and Clock messages to control the sequencer.
The START/STOP button is ignored in MIDI IN Mode,
as is any clock input present on the SYNC IN jack.
MIDI IN Mode is a clock SLAVE mode that requires
an active MIDI clock signal present on the DIN socket
to drive the sequencer's user interface. You may
need to configure your MIDI master device to
continuously send MIDI clock data (see NOTE).
When the sequencer is stopped, the 880 may be
used as a MIDI drum module. The BASS DRUM is
triggered from MIDI note 0 (C−2) and the rest of the
voices are mapped across the MIDI note scale up to the
MARACAS on MIDI note 15 (D#−1). MIDI notes with a
velocity value greater than 63 will be accented.
To c h an ge th e 8 8 0' s M I DI r e ce i ve c h an n el se e Q u ic k
Tips on Page 5.
NOTE: MIDI triggering of drum voices is only enabled in
MIDI IN mode with the sequencer stopped. To use the
880 as a MIDI drum module you will need to configure
your MIDI master device so that it doesn't send MIDI
transport control (Start, Stop, Clock).
The 880's sequencer can be synchronized to
incoming MIDI clock, DIN Sync24, or an external
clock pulse present on the SYNC IN input jack.
12
Synchronization
DIN Sync24 Out
Mode
Connect a DIN cable (pins 1 and 3 must be wired; not
all MIDI cables will function as DIN Sync cables) to the
DIN sockets of the 880 and the slave device. Set the
slave device's sync setting to IN.
NOTE: Unlike MIDI, the DIN Sync standard requires a
ground connection between devices. See DIN Socket
Ground Setup on Page 3.
This mode is a MASTER clock mode that configures
the DIN socket as a DIN Sync Output so that the 880
can be used as a DIN Sync Master device.
DIN Sync is a legacy sync interface common on
vintage Roland instruments and sequencers. It uses a
24 Pulses Per Quarter Note (PPQN) clock signal and
a Run/Stop signal for transport control.
DIN Sync24 In
Mode
DIN Sync24 In Mode is the first of the SYNC IN modes
that depends on an analog clock signal (as opposed to
a digital MIDI signal). This mode allows the 880 to
operate as a DIN Sync slave device.
Connect a DIN cable between the 880 and the master
DIN Sync device. Set the master device's sync setting
to OUT.
The 880 is now dependent on the clock and run/stop
control from the master device.
See NOTE above about DIN grounding.
(cont.)
Sync In Clock
Mode
The second SYNC IN mode depends on a clock signal
from the Sync In jack next to the DIN socket.
When entering Sync In Clock Mode, the SYNC LED
will glow red if there is no clock signal and will flash
orange if a valid clock signal is detected on the SYNC
IN jack.
The Sync In Clock uses a Korg Volca standard 2
PPQN in contrast to the 24 PPQN used by both MIDI
and DIN Sync.
The START/STOP button must be used to control
sequencer transport when in Sync In Clock mode. A
run/stop input will be implemented on a planned
TRIGGER/SYNC expander module.
Run/stop control may also be added via a future
update using a specialized DIN to 3.5 mm adapter
cable.

FIRMWARE UPDATE TROUBLESHOOTING:
If the 880 does not accept the firmware the SYNC LED
will remain solid red and the current firmware will not
be overwritten. Turn the 880 off and then on again
without holding the START/STOP button to boot into
the current firmware or power the 880 on while holding
down the START/STOP button to try again.
If the 880 begins to receive the firmware (SYNC LED
turns yellow and flashes rapidly) but the transmission is
interrupted then the existing firmware is partially
overwritten and the 880 will not function. Do not panic.
Power off the 880 and power it on again while holding
down the START/STOP button. Wait until the SYNC
LED turns solid red and then try sending the sysex
firmware update file again.
The 880's firmware may be periodically updated to fix
bugs and add features. Please check
www.system80.n et/produc t/880/ for official firmware
updates.
A computer, MIDI interface, and software capable of
sending a MIDI sysex file are required to update the
880's firmware. Both MIDI-OX (www.midiox.com) for
Windows/PC and Snoize SysEx Librarian
(www.snoiz e.com/Sy sExLibr arian/) for Mac OS are
recommended software utilities for sending MIDI sysex
files .
Follow these steps to update the firmware:
1. Download the latest MIDI sysex firmware update file
to your computer from the System80 website.
2. With the 880 powered off, plug a MIDI cable from
your MIDI interface to the MIDI-DIN socket on the
880.
3. Power on the 880 while holding down the START/
STOP button. Continue to hold the START/STOP
button until the SYNC LED turns red. The 880 is
now ready to accept the firmware sysex file.
4. Using your MIDI utility software, send the MIDI
sysex firmware update file to the 880. When the 880
recognizes and begins to load the new firmware the
SYNC LED will turn yellow and begin flashing very
rapidly. The SYNC LED will remain solid red if the
firmware is not being received.
5. Wait until your MIDI utility software finishes sending
the sysex firmware update file. When complete the
880 will reboot with the new firmware installed.
