AI4AVSummary
The Meyer Sound GALAXY Network Platform is a loudspeaker management processor exposing a Control Plane server that lets multiple clients (Compass software, Compass Go, Spacemap Go, or third-party controllers) exchange control and status messages over the network. The server speaks two protocols: a line-oriented ASCII command set on TCP and Open Sound Control (OSC) over either TCP or UDP. Addressable control points cover snapshot recall/management, per-input and per-output processing (mute, gain, delay, EQ, highpass/lowpass, polarity, ushaping, atmospheric), matrix cross-points, device I/O configuration, project settings, and entity identification. This spec covers the ASCII and OSC interfaces; it does not cover Compass application behavior.
Transport
# The GALAXY server supports three transport bindings simultaneously:
# - ASCII over TCP/IP (port 25003 for physical GALAXY 1; +100 per additional physical)
# - OSC over TCP/IP (port 25004 for physical GALAXY 1; +100 per additional physical)
# - OSC over UDP (same port 25004; UDP has a 30-second keepalive requirement)
#
# Virtual GALAXY: ASCII port 50503 (OSC 50504) for virtual #1, decrement by 100 per
# additional virtual in Normal mode; in Spacemap mode use 25003 (OSC 25004) and
# increment by 100 per additional virtual.
#
# IPv4, IPv6, and mDNS addresses are all accepted (e.g. `telnet 192.168.71.146 25003`
# or `telnet MyGalaxy.MyGroup.local 25003` or
# `telnet mslg-gx-816-16342723.local 25003`).
protocols:
- tcp
- udp
- osc
addressing:
port: 25003 # ASCII TCP server (default physical GALAXY 1)
osc_port: 25004 # OSC TCP/UDP server (default physical GALAXY 1)
ascii_port_virtual_normal: 50503 # ASCII port for first virtual GALAXY (Normal mode)
osc_port_virtual_normal: 50504 # OSC port for first virtual GALAXY (Normal mode)
ascii_port_virtual_spacemap: 25003 # ASCII port for first virtual GALAXY (Spacemap mode)
osc_port_virtual_spacemap: 25004 # OSC port for first virtual GALAXY (Spacemap mode)
auth:
type: none # inferred: no auth procedure in source
notes:
- "All ASCII text messages must terminate with CR (0x0d) or LF (0x0a)."
- "OSC over TCP uses 4-byte big-endian length prefix; OSC over UDP is unprefixed."
- "UDP subscription lifetime: 30 seconds since last packet; resend empty /ping to keep alive."
- "Telnet is not available on current macOS - use `nc` instead."

Macros
# Multi-step sequences that the source documents as a single logical operation.
# The recall_snapshot exclusion argument is documented as a single command
# (not a macro) so it is represented in recall_snapshot's params, not here.
# UNRESOLVED: source does not document any higher-level multi-step macros
# (e.g. "save project", "reboot into snapshot N"). Remove this section if
# none are added after real-device verification.
[] # UNRESOLVED: no multi-step macro sequences in source
Safety
confirmation_required_for: []
interlocks: []
# UNRESOLVED: source does not document safety warnings, interlocks, or
# power-on sequencing requirements. The snapshot recall command can
# immediately change live audio routing/levels, but no explicit safety
# procedure is stated. Do not infer.
Notes
- The control plane listens on both ASCII (port 25003) and OSC (port 25004) simultaneously for the same physical device. ASCII uses CR/LF-terminated text; OSC uses 4-byte length-prefixed packets on TCP and unprefixed datagrams on UDP.
- Telnet is unavailable on current macOS; use
ncper the source. mDNS names followmslg-gx-{408|816|816aes|bluehorn}-{serial}.localorEntity.Group.local. - Virtual GALAXY instances are port-shifted: in Normal mode ASCII starts at 50503 (OSC 50504) and decrements by 100 per additional virtual; in Spacemap mode both start at 25003/25004 and increment by 100 per additional virtual.
- Subscribe/unsubscribe apply the same syntax to all control points; the path may contain regular-expression tokens (
.,*,\d,\d+, character classes) to address many points in one command. Maximum 232 matrix cross-points may be set simultaneously. - Boolean values accept both
true/false,T/F, and integer 1/0; the server type-casts positive non-zero integers to True per the source. - Status control points (
/status/...) are read-only — setting them returns an error. - Default values shown in the source tables (e.g. EQ center frequencies, link-group IDs, network settings) are GALAXY-816 representative; other models may differ.
