Method. s0 specifies the message type as defined in
. s1 specifies the program number, CC
number, or note number.

3.2.4 Preset State (nn, k0-k7)
Byte nn specifies the number of the preset defined by the following 8 bytes. nn corresponds to the MIDI program, CC, or note number used to recall the preset. The MSA can store up to 128 presets. The valid range for nn is 00h-7Fh.
Byte k0-k7 specify the states of MSA outputs 0-7. For these bytes, a value of 00h sets the output to off, and a value of 01h sets the value to on.

4.0 Factory Default Configuration
By default, MSA outputs 0-7 respond individually to MIDI notes 60-67. Presets are recalled by Program
Change messages. The default configuration can be expressed as one Individual Output Configuration
Sysex message and one Preset Configuration Message as shown in

5.2 Output Configuration Retrieval
The current MSA configuration can be retrieved via the MSA MIDI Out port.
If the MSA receives a SysEx message as described in
, it will send its configuration as an
Individual Output Configuration SysEx Message.
If the MSA receives a SysEx message as described in
it will send its
configuration as a Preset Configuration SysEx Message.

Highly Liquid MSA Firmware V. 3.2
6.0 DIP Switch
The MSA DIP switch serves two main purposes: to set the MIDI channel for MIDI input, and to set the
6.1 MIDI Channel
The MSA DIP switch is used to specify the MIDI channel for incoming MIDI messages. During normal operation, the MSA will respond only to messages received on this channel.
6.2 Unit ID
Each configuration SysEx message contains a Unit ID byte.
If the Unit ID byte is 00h, any MSA unit receiving the message will configure itself as directed by the message.
If the Unit ID byte is between 1 and 16 (01h to 10h), any MSA receiving the message will update its
configuration only if its DIP Switch setting matches the Unit ID. This allows the user to target &
configure a single MSA within a chain of multiple units.

7.0 Activity LED
The MSA activity LED performs several functions:
●
●
●
●
●
●
Self test: Upon power-up or device reset, the activity LED lights briefly before normal operation begins.
Configuration update indication: The LED blinks 3 times when the MSA configuration is updated via a MIDI SysEx message. If no LED activity is observed, then the attempted configuration was unsuccessful.
MIDI activity indication: The LED blinks when a MIDI message is received that affects the
MSA output state. Other MIDI messages will not cause an activity indication.
Individual output control learn mode indication: The LED will blink slowly while the MSA awaits MIDI messages during Learn Mode.
Preset store: The LED blinks twice when a preset state is stored using the Preset Control Learn
Firmware update error: The LED blinks continuously when the receipt of a firmware update
SysEx message has failed, or when the firmware has become corrupt.

Highly Liquid MSA Firmware V. 3.2
8.0 Firmware Update
MSA firmware can be upgraded via MIDI SysEx message. Firmware update files, when available, can be downloaded from the MSA product page at highlyliquid.com.
8.1 Firmware Update Procedure
1. Download and unzip the firmware update SysEx message. The resulting file should have the extension “.syx”.
2. Disconnect power to the MSA.
3. Press and hold the PRGM switch. (See MSA Hardware User Manual.)
4. Reconnect power to the MSA. The activity LED will remain lighted.
5. Send the firmware update SysEx message to the MSA. Transmission of the message may require several seconds.
6. Upon completion of the update, the activity LED will deactivate.
7. Release the PRGM switch.
8. Disconnect power to the MSA.
8.2 Notes
•
•
•
•
Do not interrupt the transmission of the firmware update SysEx message.
A continuously blinking activity LED indicates an error in the transmission of the firmware update SysEx message.
If a continuously blinking activity LED is observed, repeat the procedure from the beginning.
The current firmware version can be retrieved via Identity Request / Identity Reply SysEx
messages.
