Qu Mixer MIDI Protocol V1.9+ 1 CD 13/03/2017 iss.1
Qu Mixer MIDI Protocol - Firmware V1.9+ March 2017
This protocol is for use with the Qu-16, Qu-24, Qu-32, Qu-Pac and Qu-SB loaded with firmware version
V1.9 or later.
Note Firmware V1.9 added new MIDI messages for:
Remote shutdown command added.
Note For firmware V1.5 onwards the MIDI channel numbers and NRPN ID previously used by Mute
Groups were re-allocated to the added DCA Groups to be consistent with other Allen & Heath mixers.
Mute Groups channel numbers were changed and are as detailed in this specification.
Qu transmits MIDI messages when its controls are operated. It also responds to parameter changes it
receives via MIDI, for example from a computer or an external MIDI controller.
MIDI communicates via:
USB – Rear panel USB B port for direct connection to Apple Mac computers running OSX 10.6 or later.
This is the recommended connection for DAW control.
Note USB MIDI is supported natively by Apple Mac computers so no driver is needed. A driver for
Windows computers can be downloaded from the Allen & Heath web site.
TCP – Rear panel network port for use with a computer, a touch panel or other remote controller with
configurable MIDI over a TCP/IP port.
Note TCP MIDI requires a driver for the data to be seen as a MIDI port. An Allen & Heath TCP MIDI driver
for Apple Mac computers can be downloaded from the iLive Software web page. A driver is not available
for Windows computers.
Note Qu currently allows only one TCP MIDI connection at a time over its Network port.
The following Qu functions can be controlled via MIDI:
Mutes
Faders and Pan
Mix and FX sends - Level, Pan, Assign, Pre/Post
Matrix sends (not Qu-16) – Level, Pan, Assign, Pre/Post
Audio Groups (not Qu-16) – Assign, (plus Level, Pan, Pre/Post if in Mix mode)
Mute Groups – Assign, Master Mute
DCA Groups – Assign, Master Level, Master Mute
PAFL select
Input Channel source
Preamp (local and dSNAKE) – Gain, Pad, 48V
Insert In/Out
Input Channel processing – Trim, Polarity, Gate, PEQ, Compressor, Delay
Mix processing - PEQ, GEQ, Compressor, Delay
Group and Matrix processing – PEQ, GEQ, Compressor, Delay (not Qu-16)

DAW Control for Mac computers:
MIDI fader strips can be assigned to the Custom Layer to work with a DAW (Digital Audio Workstation).
These send/receive CC and note on/off messages using a different MIDI channel to that used for the Qu
functions described above. The MIDI fader strip sends/receives messages relating to:
Fader position
Mute key / indicator
Sel key / indicator
PAFL key /indicator
DAW Bank Up/Down
You can work directly with these messages or use the Allen & Heath DAW Control driver to convert them
into either of the following popular protocols:
HUI
Mackie Control
Note DAW Control is available for Mac computers only. A driver for Windows computers is not available.
Go to the Allen & Heath web site to download the DAW Control driver for Mac and for further information in
the DAW Control Setup Notes.
Reference
Refer to the table at the end of this document for value listings.
All MIDI message numbers shown in blue in this document are Hexadecimal
Key Blue Hexadecimal number, eg, F0
Green Variable referred to in table or note, eg, VA = parameter value
Red NRPN ID number for parameter type, eg. Polarity = 6A
Orange NRPN Index to specify a second value, eg, VX
MIDI channel number N (see table)
MIDI channel 1 to 16 = 0 to F
Qu functions use MIDI channel = N
MIDI strips (DAW controls) use MIDI channel = N+1
Channel numbers CH (see table)
FX Send 1 to 4 = 00 to 03
FX Return 1 to 4 = 08 to 0B
DCA Groups 1 to 4 = 10 to 13 Note Introduced in V1.5 firmware
Input 1 to 32 = 20 to 3F
Stereo Channels = 40 to 42
Mute Groups 1 to 4 = 50 to 53 Note This is a change introduced in V1.5 firmware
Group 1-2 to 7-8 = 68 to 6B (not Qu-16)
Mix 1 to 10 = 60 to 66
Main LR = 67
Matrix 1-2, 3-4 = 6C , 6D (not Qu-16)
Active Sensing
Qu supports MIDI Active Sensing over its TCP/IP Ethernet connection to detect connection
status. Qu will send an initial Active Sense byte (FE) once an Ethernet connection is established,
and then once every 300ms or so during any period of inactivity.
Qu also responds to Active Sense If it receives an Active Sense byte it will expect to receive
regular MIDI data from that point onwards (either valid control data, or more Active Sense bytes
during any period of inactivity). If it does not receive any data for 12 seconds, it will close the
Ethernet connection.

DAW control
MIDI strips assigned to the Custom Layer can provide DAW control.
DAW messages can be translated into HUI or Mackie Control protocol using the Allen & Heath
DAW Control driver which can be downloaded from the Allen & Heath web site.
Note DAW Control is available for Mac computers only. A driver for Windows computers is not
available.
DAW messages use a different MIDI channel to other Qu MIDI messages:
Qu MIDI channel = N
DAW MIDI channel = N+1
MIDI strip controls send and respond to the following messages:
Strip Fader
Control Change message:
B(N+1), FD, VA
Where FD = Strip fader 00 to 1F (see table)
VA = Fader min to max position = 00 to 7F
Strip keys
The strip keys use NOTE ON followed by NOTE OFF messages.
Pressing keys send messages.
Key LED indicators respond to received messages.
9(N+1), KY, 7F, 9 (N+1), KY, 00
Where KY = Mute Strip 1-32 = 00 to 1F (see table)
Sel Strip 1-32 = 20 to 3F
PAFL Strip 1-32 = 40 to 5F
Bank Up/Down
Qu SoftKeys can be assigned as DAW Bank Up or Bank Down keys.
These use NOTE ON followed by NOTE OFF messages which are converted by DAW Control to
become the Bank Up/Down control.
Bank Up 9(N+1), 7E, 7F, 9(N+1), 7E, 00
Bank Down 9(N+1), 7F, 7F, 9(N+1), 7F, 00

Received Mute messages
Velocity 00 and NOTE OFF messages are ignored
Velocity 01 to 3F = Mute off
Velocity 40 to 7F = Mute on
NRPN Parameter control
Qu mixer parameters are transmitted and received as MIDI NRPN (Non-Registered Parameter
Number) messages. The MSB (most significant byte) selects the mixer channel (CH), and the
LSB (least significant byte) selects the parameter number (ID). The data entry MSB sets the
parameter value (VA) and LSB sets the index value for its range (VX) where needed.

Device Connection
Note Qu currently allows only one TCP MIDI connection at a time over its Network port.
TCP Client Configuration
Clients should be configured to use TCP port 51325
Active Sensing
Qu supports MIDI Active Sensing over its TCP/IP Ethernet connection to detect connection
status. Qu will send an initial Active Sense byte (FE) once an Ethernet connection is established,
and then once every 300ms or so during any period of inactivity.
Qu also responds to Active Sense If it receives an Active Sense byte it will expect to receive
regular MIDI data from that point onwards (either valid control data, or more Active Sense bytes
during any period of inactivity). If it does not receive any data for 12 seconds, it will close the
Ethernet connection.
Qu uses Sysex messages to communicate much of its data.
Sysex Header Sysex Header
A&H ID Qu mixer Major/Minor version MIDI channel
F0, 00, 00, 1A, 50, 11, 01, 00, 0N
Get System State
An external controller such as an iPad running the Qu-Pad app can use MIDI Sysex messages to
request and receive the current parameter state of the Qu mixer.
Note On request, the mixer MIDI channel ( N ) is not known therefore an ‘All Call’ Sysex Header
is sent. The reply returns the MIDI channel number. This number should be used in subsequent
messages.
REQUEST: Sysex Header (All Call), 10 <iPadFlag>, F7
Where Sysex Header (All Call) = F0, 00, 00, 1A, 50, 11, 01, 00, 7F
And <iPadFlag> = 1 identifies the incoming connection as Qu-pad.
REPLY: Sysex Header, 11, < BoxID > , < Version > , F7
Where < BoxID > identifies the outgoing connection Qu mixer model
Where: 1 = Qu-16
2 = Qu-24
3 = Qu-32
4 = Qu-Pac
< Version > = <Major>,<Minor> = Qu firmware version (7bit data)
Subsequent push of NRPN messages to update current state.
Subsequent End Sync Response:
Sysex Header, 14, F7
If <iPadFlag> is set in the initial request the Qu mixer will expect to receive an Active Sense byte
within 5 seconds. If not, it will close the Ethernet connection. This is how the lost communication
mechanism is enforced for Qu-Pad.
Qu Mixer MIDI Protocol V1.9+ 10 CD 13/03/2017 iss.1
Channel Naming

REQUEST: Sysex Header, 01, CH, F7
REPLY: Sysex Header, 02, CH, <Name>, F7
Where < Name > = string of hex ascii characters
Set Name Sysex Header, 03, CH, <Name>, F7
Where < Name > = string of hex ascii characters
Get Meter Data
An external controller such as an iPad running the Qu-Pad app can use MIDI Sysex messages to
request and receive the current meter data from the Qu mixer.
REQUEST:
Sysex Header, 12, < MeterOnOff > , F7
REPLY:
Sysex Header, 13, < MeterData > , F7
Where < MeterData> = Push of all meter data (Described below).
Where < MeterOnOff> = 0 (meters Off), 1 (meters On)
Meter values are signed dB values, coded as fixed point 7Q8 offset 8000 format, stored as
unsigned 16 bit numbers, (transmitted in “7-bit-ized” format in the Sysex).
Encoding of meter data:
The 8-bit file data needs to be converted to 7-bit form, with the result that every 7 bytes of file
data translates to 8 bytes in the MIDI stream.
For each group of 7 bytes of file data, the top bit from each is used to construct an eighth byte,
which is sent first. For example:
AAAAaaaa BBBBbbbb CCCCcccc DDDDdddd EEEEeeee FFFFffff GGGGgggg
becomes :
0ABCDEFG 0AAAaaaa 0BBBbbbb 0CCCcccc 0DDDdddd 0EEEeeee 0FFFffff 0GGGgggg
The final group may have less than 7 bytes, and is coded as follows (example with 2 bytes in the
final group):
0AB00000 0AAAaaaa 0BBBbbbb
Example: 7-bit-ized binary 00100000 01111100 00000000
Unpacks to 8-bit-ized binary 01111100 10000000
Equivalent to hexadecimal 7C80
Remove the offset: (int16_t) 7C80 – (int16_t) 8000 = FC80
Float and scale: (float) FC80 / 256.0f = -3.5dB
