GRANDMOTHER FIRMWARE UPDATE V1.1.0 Sept 23, 2020
Firmware version 1.1.0 for the Grandmother contains a number of new features as well as some bug fixes.
HOW TO UPDATE YOUR FIRMWARE
1. Connect a USB cable from Grandmother to your computer.
2. Open your SysEx sending software.
NOTE: We recommend downloading Bome SendSX for Windows or SysEx Librarian for Mac.
3. In the SysEx software, select Grandmother as your MIDI output device.
NOTE: In SysEx Librarian, this is located in the drop-down menu at the top of the application window.
In Bome SendSX, this is located in the MIDI OUT menu on the menu bar.
4. Select the SysEx file “Grandmother_FIRMWARE_INVALIDATE.syx” included with this download
and click Send. On the Grandmother, the Arp Rate LED will start blinking red/green.
5. In the SysEx sending software, re-select Grandmother as your MIDI output device (Grandmother
reboots and needs to be re-selected after INVALIDATE).
6. Select the SysEx file “Grandmother_FIRMWARE_ERASE.syx” included with this download
and click Send. On the Grandmother, the Arp Rate LED will blink red three times then blink green steadily.
Grandmother is now ready for new firmware.
7. Select the new firmware file “Grandmother_Firmware_v1_1_0.syx” included with this download
and click Send. The Grandmother Arp Rate LED will blink yellow-orange while receiving.
8. You’re done! Grandmother will reboot to the new firmware when done.
TROUBLESHOOTING
If the Grandmother Arp Rate LED is still blinking yellow-orange after the firmware has finished sending,
or if the Arp Rate LED stops blinking and the unit does not reboot automatically once firmware has
finished sending, you should try again.
Turn the Grandmother power off and on again, disconnect and reconnect the USB cable, and
then start over at step 1.
You can retry as many times as necessary and it will not hurt the hardware. If it doesn’t work after two
or three tries, you should contact Moog Technical Support for further assistance.
If you have any questions or trouble with your update please contact [e-mail].

CHANGES SINCE V1.0.6:
• Synchronization and Timing Engine update - Analog Clock in/out and MIDI Clock all remain tightly in phase now,
eliminating the possibility of drift between these clocks which was present in earlier firmware.
• New Behavior: HOLD button acts like a Sustain Pedal (KB Hold) when Arp/Seq is not running.
• The default setting for CLOCK INPUT PPQN and CLOCK OUTPUT PPQN was changed from expecting/outputting a
clock every 8th note, to expecting/outputting a clock every 16th note (changed from 2 PPQN to 4 PPQN).
• Arp/Sequencer Gate Length can be adjusted using MIDI CC 106. Value 64 = 50% gate length (default).
• External Analog Clock overrides MIDI Sync.
• Added Arp/Seq Swing parameter (MIDI CC 14; global param ID 22).
• Added Multi-Trig parameter (MIDI CC 95).
• Arp/Seq PLAY button does not output MIDI CC 73 (can still respond to it if necessary).
• Improves compatibility with other Grandmother/Matriarchs.
• Changed MIDI Clock Output default setting to “Off”.
• Can now edit global parameters via MIDI SysEx messages (documented below).
• This also exposed a number of previously-hidden parameters which can now be edited.

GLOBAL SETTINGS
To access Grandmother’s Global Settings, simultaneously press and hold the HOLD button (on the Left-Hand
Controller) and SYNC button (in Oscillator 1) until the SYNC button begins to blink. Now you can use the keyboard
commands listed below to make any needed changes to the Global Settings. The SYNC button will continue to blink a
number of times to indicate which Global Setting is currently selected. When you have finished making any changes,
simply press the SYNC button to exit the Global Settings edit mode.
TIP: You can also double-tap your Global Settings selection on a white key to update a setting and exit the edit mode.
NOTE: Global Settings are retained even when the power has been turned off.
For information on advanced Global Settings visit www.moogmusic.com/grandmother.
HERE’S HOW IT WORKS
Global Settings are organized in groups of ten. An individual parameter in the chosen group is selected using one of
the lower 10 black keys, starting with F#0. The white keys, starting with F0, are used to set the value of the chosen
parameter. The first 10 parameters are in the default group, and no group selection is required. Additional groups are
selected using one of the upper black keys, starting with F#2. To access these additional parameters, hold down a
Group Select key while pressing the individual Parameter Select key.

0.7 Clock Input PPQN (none) G#1
To be sure that Grandmother’s Sequencer and Arpeggiator sync correctly to an External Clock, you can determine how many
pulses are received per quarter note (PPQN). To edit the PPQN value, first press the (G#1) key, and then use the first eight white
keys to choose the number of clock pulses received per quarter note. (F0) = 1 PPQN; (G0) = 2 PPQN; (A0) = 3 PPQN; (B0) = 4
PPQN; (C1) = 5 PPQN; (D1) = 6 PPQN; (E1) = 7 PPQN; (F1) = 8 PPQN; (G1) = 9 PPQN; (A1) = 10 PPQN; (B1) = 11 PPQN; (C2) = 12
PPQN; (D2) = 24 PPQN; (E2) = 48 PPQN. The Default is 4 PPQN (sixteenth note clock).
0.8 Clock Output PPQN (none) A#1
To be sure that external devices sync correctly to Grandmother’s Sequencer and Arpeggiator, you can set how many pulses are
sent per quarter note (PPQN). To edit the PPQN value, first press the (A#1) key, and then use the first eight white keys to choose
the number of clock pulses sent per quarter note. (F0) = 1 PPQN; (G0) = 2 PPQN; (A0) = 3 PPQN; (B0) = 4 PPQN; (C1) = 5 PPQN;
(D1) = 6 PPQN; (E1) = 7 PPQN; (F1) = 8 PPQN; (G1) = 9 PPQN; (A1) = 10 PPQN; (B1) = 11 PPQN; (C2) = 12 PPQN; (D2) = 24 PPQN;
(E2) = 48 PPQN. The Default is 4 PPQN (sixteenth note clock).
0.9 KB Out Range (none) C#2
The voltage range of Grandmother’s KB OUT (pitch CV) jack can be either -5 to +5 Volts, or 0 to 10 Volts. To adjust the KB
OUT Range setting, press the (C#2) key, and then use the first two white keys to select -5V to +5V (F0), or 0V to 10V (G0). The
Default is -5V to +5V.
0.10 Local On/Off (none) D#2
Grandmother can be used to drive external MIDI devices, as well as its own internal sound engine and modules. In some cases,
you may wish to have Grandmother only controlling an external setup. By setting the Local parameter to OFF, Grandmother’s
Keyboard, PITCH wheel, and Arpeggiator are only transmitted through MIDI, and do not use any hard-wired connections to play
the internal sound engine. Additionally, when Local is set to OFF, Grandmother’s KB OUT, GATE OUT, and KB VELOCITY OUT
jacks are disengaged (because these output jacks are also hard-wired to the internal sound engine). To access the Local setting,
first press the (D#2) key, and then use the lowest two white keys to select LOCAL OFF (F0), or LOCAL ON (G0). The Default is
Local ON.

Global Parameters
Group 1 Group Select Key Parameter Select Key
1.1 Glide Type F#2 F#0
Grandmother’s Glide type can be changed to best suit playing style or preference. There are three options - Linear Constant
Rate, Linear Constant Time, and Exponential. To change Grandmother’s Glide Type, press the (F#2 + F#0) keys, and then use
the first three white keys to select LCR (F0), LCT (G0), or EXP (A0).
The Default is LCR.
1.2 Gated Glide F#2 G#0
While Glide is in use, Gated Glide allows Grandmother to transition between the pitch of two notes only when a note is pressed.
The Glide transition halts in between notes and continues when a new note is pressed. If Gated Glide is off, the transition between
the pitch of two notes completes in the amount of time set by the GLIDE knob, regardless of whether or not a note is held. To
specify the state of Gated Glide, press the (F#2 + G#0) keys, and then use the first two white keys to determine if Gated Glide is
OFF (FO), or ON (G0). The Default is ON.
1.3 Transposition Behavior F#2 A#0
This setting determines how Grandmother will behave when its Octave settings are changed via the Left-Hand Control. To
specify whether Grandmother’s pitch is transposed Immediately, or when a New Note is played, press the (F#2 + A#O) keys, and
then use the first to white keys to select New Note (F0), or Immediate (G0). The Default is New Note.
1.4 Tap-Tempo Clock Division Persistence F#2 C#1
This setting determines whether the clock divisions specified while Tap Tempo is in use will persist when Tap Tempo is
disengaged or if the clock divisions will be reset to Eighth Notes when disengaged. Press the (F#2 + C#1) keys, and then use the
first two white keys to determine whether Tap-Tempo Clock Division Persistence is OFF (F0), or ON (G0). The Default is OFF.
1.5 Velocity CV Output Range F#2 D#1
Grandmother’s VELOCITY CV Output can be set to transmit velocity data at two different voltage ranges. To set the VELOCITY
CV Output range, press the (F#2 + D#1) keys, and then use the first two white keys to select between -5V to +5V (FO), and 0V
to 10V (G0). The Default is -5V to +5V.
1.6 Oscillator 2 Frequency Knob Range F#2 F#1
Hold (F#2) and press (F#1) to select. 0 Semitones / Off (F0), 1 Semitone (G0), 2 Semitones (A0) …
7 Semitones (F1) is the Default… 18 Semitones (C3). Osc 2 Freq Knob Range controls the amount of pitch detuning available
from the FREQUENCY knob in the Oscillator 2 section of the front panel. The default is 7 semitones; the range is 0 to 18
semitones, set using any of the white keys on the keyboard (lowest to highest white key sets range to be 0 to 18 semitones).

1.7 Clock Output Mode F#2 G#1
Hold (F#2) and press (G#1) to select. Output clock only when Arp/Seq is running (F0) - Default, Output clock all the time (G0).
Clock Output Mode controls when a clock signal will be present at the CLOCK OUT jack on the Grandmother rear panel. Options
are to output clock pulses only when the internal Arpeggiator or Sequencer is running, or to output clock pulses all the time. The
timing of clock pulses is determined by the tempo in BPM and the Clock Output PPQN setting.
1.8 Multi Trig F#2 A#1
F0 = off (default), G0 = on. This setting determines how the Envelope Generators will respond to each new note press on the
keyboard. When MULTI TRIG is Off, the Envelope Generators will not retrigger until all keys on the keyboard are released, and a
new key is played. If MULTI TRIG is On then the Envelope Generators will retrigger each time a new key is played on the keyboard.
Multi Trig can also be turned on/off via MIDI CC 95.

2.1 Separate MIDI Channels G#2 F#0
To set only MIDI OUT channel, go into Global Edit mode and then press and hold the highest G# key (G#2); while holding that
also press the lowest black key (F#0). Then, the lowest 16 white keys set MIDI OUT channel 1-16. The original MIDI Channel global
option (just pressing lowest F#0 key by itself) continues to set both MIDI IN and OUT channels to the selected channel number.
2.2 MIDI OUT Filter - Panel Knobs G#2 G#0
F0 = off, G0 = on (default). This setting controls whether or not MIDI CC messages are output in response to changes made to the
front panel controls. ON is the setting that allows messages to be sent. When MIDI Out Filter - Panel Knobs is OFF, then no MIDI CC
messages are output from Grandmother in response to panel control changes.
2.3 MIDI OUT Filter - Pitch/Mod Wheels G#2 A#0
F0 = off, G0 = on (default). This setting controls whether or not MIDI CC messages are output in response to movement of the
Pitch Wheel or Mod Wheel. ON is the setting that allows messages to be sent.
2.4 MIDI OUT Filter – Keys G#2 C#1
F0 = off, G0 = on (default). This setting controls whether or not MIDI Note messages are output in response to playing on the
Grandmother keyboard. ON is the setting that allows MIDI notes to be sent.

FUNCTIONS WITHIN THE GLOBAL EDIT MODE
This firmware version introduces a couple of useful functions which are launched from within the Global Edit system.
They are selected like other global parameters, but the functions activate immediately upon being selected, since there is
no need to set any additional parameter value for them.
V1.1.0 RELEASE NOTES
Global Parameters
Group 3 Group Select Key Parameter Select Key
3.1 Load Default Settings A#2 F#0
This function resets all the global parameters to their default values. Hold the highest black key (A#2), and while holding it
press the lowest black key (F#0). You will see the three buttons on the LHC blink rapidly for a moment to confirm that the reset
happened. Resetting the global parameters also exits Global Edit mode.
3.2 Show Firmware Version A#2 F#0
This function indicates the currently-installed firmware version, using the lights on the LHC buttons. Hold the highest black key
(A#2), and while holding it press the next-to-lowest black key (G#0). Count the number of times the PL AY, HOLD, and TAP buttons
blink on/off to read the version number. PLAY = major version number, HOLD = minor version number, TAP = minuscule/bugfix
version number. Example: this version, v1.1.0: PLAY button blinks one time, then HOLD button blinks one time, then TAP button
blinks zero times (does not light at all).

EDITING PARAMETERS USING MIDI SYSEX MESSAGES
You can edit the global and some panel parameters using MIDI System Exclusive (SysEx) messages. The template for
these SysEx messages is shown below.
TO SET A PARAMETER TO A VALUE:
F0 04 16 23 [Parameter ID], [value MSB], [value LSB], 00 00 00 00 00 00 00 00 [Unit ID] F7
• Values above are shown in hexadecimal format.
• If the intended parameter value is less than 128, then [value MSB] is 0 and [value LSB] is the intended parameter
value. If the intended parameter value is 128 or higher, then the value MSB is the intended value divided by 128, and
the value LSB is the remainder (intended value modulo 128).
• The Unit ID byte must be set to match the Unit ID of the synth you want to edit (all synths are set to Unit ID 0 by
default; this value will be 0 unless you change it) or set the Unit ID value to 0x7F to address any Unit ID, or multiple
units with different IDs sharing the same MIDI port.
• Note: The byte before Unit ID (byte 14 if counting from F0 = 0) must be set to zero or the message will be
ignored. This is because the same kind of SysEx message is output by the unit in reply to a request to get
the value of a parameter (see below). Replies output by the unit have the byte before Unit ID set to 1,
to avoid getting stuck in a MIDI feedback loop if these messages are echoed back to the unit.
TO REQUEST A PARAMETER VALUE:
F0 04 16 3E [Parameter ID] 00 00 00 00 00 00 00 00 00 00 [Unit ID] F7
• Values above are shown in hexadecimal format.
• Unit ID must match the Unit ID of the Grandmother, or set Unit ID = 7F (all).
• Grandmother will reply with a “set parameter” SysEx message for the requested Parameter ID with its current value,
with the byte before the Unit ID (byte 14 if counting from F0 = 0) set to 1 to indicate that the message is a reply
coming from Grandmother.
