AI4AVSummary
The Meyer Sound Galileo GALAXY 816 is a network loudspeaker management processor in the GALAXY Network Platform family. This spec covers the device's Control Plane server, which exposes two parallel text/binary protocols: a human-readable ASCII server (TCP) and an Open Sound Control (OSC) server (TCP and UDP). Clients (Compass software, Spacemap Go, or third-party controllers) connect over IPv4, IPv6, or mDNS to set, query, describe, subscribe, and unsubscribe from a large tree of OSC-style control points, and to invoke a small set of built-in snapshot/ping commands.
Transport
protocols:
- tcp
- udp
- osc
addressing:
port: 25003 # ASCII server (TCP)
# The OSC server listens on TCP and UDP port 25004. Virtual GALAXY processors use
# additional port schemes - see Notes.
auth:
type: UNRESOLVED # source does not state this (was inferred none: no auth procedure in source)
Connection examples (verbatim from source):
- TCP/IPv4 ASCII:
telnet 192.168.71.146 25003 - TCP/IPv6 ASCII:
telnet fe80::21c:abff:fe00:584c%en12 25003 - mDNS ASCII:
telnet MyGalaxy.MyGroup.local 25003ortelnet mslg-gx-816-16342723.local 25003
Addressing model: the device accepts IPv4, IPv6, or mDNS addresses equivalently. GALAXY exposes two servers — an ASCII server (TCP, port 25003) and an OSC server (TCP and UDP, port 25004). Authentication is not described in the source.
Traits
# Populated from explicit source evidence:
# - queryable (get/describe control point commands present)
# - levelable (input/output gain, mute, delay, EQ settable)
# - routable (matrix processing control points present)
# Power on/off is NOT in the source - no `powerable` trait.
Actions
# CRITICAL: every ASCII text command must end with a CR (`0d`) or LF (`0a`)
# terminator. The OSC equivalents use the same OSC address space with type-tagged
# arguments. Listed verbs are the source's 6 built-in commands plus the 5
# control-point characters (=, no-char, ?, +, -).

Events
# Unsolicited notifications the server may send:
- id: subscribed_control_point_update
label: Subscribed Control Point Update
description: |
When a control point is subscribed to (via `+` ASCII or `/subscribe/...` OSC),
the server pushes the current value and all subsequent changes to the
subscriber at the requested rate (0-100 ms; default 30 ms).
direction: server -> client
triggered_by: subscribe_control_point
- id: pong
label: Pong Response
description: |
Returned by the server in response to a :ping (ASCII) or /ping (OSC) command.
Includes the keyword string supplied by the client. Source notes: a client
cannot send a pong command - pong is only ever a server reply to ping.
direction: server -> client
triggered_by: ping
Macros
# UNRESOLVED: source documents no multi-step macro sequences.
Safety
confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no safety warnings, interlock procedures, or
# power-on sequencing requirements.
Notes
Termination. All ASCII text commands must end with a CR (0d) or LF (0a) byte. The command strings in the Actions section show the printable form without the terminator; implementations must append 0d or 0a.
OSC argument types. OSC supports: i 32-bit integer, f 32-bit float, s string, F Boolean false, T Boolean true, h 64-bit integer. Source notes: "Because some clients do not adhere to the OSC protocol governing argument types, GALAXY is programmed to type cast from integer to Boolean. For example, Boolean True is any positive non-zero integer."
Subscription lifetimes.
- TCP: subscription remains active until an unsubscribe or until the TCP connection breaks.
- UDP: subscription remains active until an unsubscribe or until the server receives no UDP packets from the client for at least 30 seconds. Use a no-arg
:ping(or empty OSC ping) as a keepalive.
Regular expressions. Address fields support regex wildcards: . (any single char), * (any sequence), \d (any single digit), \d+ (any integer). Example: /processing/input/\d/mute=true mutes inputs 1-8; /processing/output/\d+/mute=false unmutes all outputs.
Snapshot exclusion codes (for recall_snapshot second argument, sum to combine):
- 1 = exclusion enabled, nothing excluded
- 2 = Input Channel Types
- 4 = Input and Output Voltage Ranges
- 8 = Input and Output Mute
- 16 = Update active snapshot before recall
- 32 = SIM3 Bus Address
- 64 = SIM3 Probe Point
- 128 = Clock Sync Mode
- 256 = AVB Configuration
Virtual GALAXY ports. Physical GALAXY devices use ASCII port 25003 and OSC port 25004. Virtual GALAXY processors use a different port scheme depending on operating mode:
- Normal mode: virtual #1 starts at ASCII 50503 / OSC 50504. Decrement by 100 per additional virtual processor.
- Spacemap mode: virtual #1 starts at ASCII 25003 / OSC 25004. Increment by 100 per additional virtual processor.
- Check the Log tab in Compass to determine the port address of any specific GALAXY device.
Operating modes. The GALAXY has two independent operating modes: normal (loudspeaker management via Compass / Compass Go) and Spacemap (spatial mixing via Spacemap Go). Port numbering for virtual processors differs between modes.
mDNS addressing. Two constructions: (1) <Entity Name>.<Group Name>.local per Compass config, or (2) <device-type-serial>.local where device type is mslg-gx-408, mslg-gx-816, mslg-gx-816aes, or mslg-gx-bluehorn. Example: mslg-gx-816-16342723.local.
Client tooling. Source notes: "Telnet is not available on the current macOS. Use the netcat command (nc) instead."
OSC path typo in source. The source's OSC MSG example for update_snapshot shows /update_snaphot,i 6 (misspelled). The accompanying ASCII Hex bytes spell the path correctly as update_snapshot, and the same spelling is used for ASCII and for the UDP/TCP OSC hex forms. This spec uses the canonical update_snapshot spelling in all action commands.
OSC type typo in source. The source's connected_osc_upd_client_count (UDP) is a misspelling of udp; the same default is shown under the clearly-intended connected_osc_udp_client_count elsewhere. This spec uses connected_osc_udp_client_count.
Status read-only. All /status/... control points are read-only. Attempting to set a status control point returns an error message. Default values shown are representative and may differ per device.
Entity defaults vary by device. Source explicitly notes that only input_channel_count, input_stream_count, output_channel_count, and output_stream_count entity defaults are consistent across all GALAXY devices; other entity defaults (entity_id, entity_name, serial_number, firmware_version, group_name, etc.) are device-specific.
Snapshot range. Snapshots are numbered 0-255. Snapshot 0 is "Factory Defaults" and is locked by default. Recall via :recall_snapshot requires the snapshot to already exist (except :create_snapshot); the active snapshot ID is -1 when no snapshot is selected.
Unknown input/output defaults on isolated controls. The source lists /device/output/atmospheric/altitude with default 0 and /device/output/atmospheric/temperature with default 293.15 (Kelvin). The same atmospheric control points appear under /processing/output/.../atmospheric/... with different defaults (gain=10, bypass=true, distance=0). Both trees are present in the source.
