Allen & Heath dLive Control Spec

Summary

The Allen & Heath dLive is a digital mixing system (Surface + MixRack). This spec covers the dLive MIDI-over-TCP/IP control protocol documented for firmware V1.9 and later. Control messages use the MIDI message format (Note On/Off, NRPN, Pitchbend, SysEx, Program Change, MMC) carried over a TCP/IP socket on any Network port of the dLive Surface or MixRack. A TLS/SSL variant requires profile/password authentication on socket open.

Transport

protocols:
  - tcp  # MIDI message format carried over TCP/IP; "midi" is the encoding, not a separate transport
addressing:
  port: 51325  # without encryption (Rendezvous port)
  port_tls: 51327  # with TLS/SSL encryption
  notes: "TCP/IP control available via any Network port on the dLive Surface or MixRack."
auth:
  type: credentials
  notes: >
    Authentication applies to the TLS/SSL socket (port 51327) only.
    On socket open, the first data sent must be: 'UserProfile, UserPassword'
    where UserProfile = 00 to 1F. If username and password match, the unit
    responds with the six characters 'AuthOK'; otherwise the connection is
    dropped. The plain socket (port 51325) requires no authentication.

Traits

traits:
  - levelable   # inferred: fader levels, send levels, preamp gain, PEQ/HPF control present
  - queryable   # inferred: multiple Get SysEx/NRPN query commands returning state present
  - routable    # inferred: input-to-main/group/aux assign, DCA assign, mute-group assign present

Actions

# SysEx Header (applies to all SysEx messages below) = F0, 00, 00, 1A, 50, 10
# Variables: N = base MIDI channel (0-B for MIDI channels 1-12); CH = note number
# selecting channel type/number (see Channel Selection table in source).
# [9N]/[BN] = bytes omitted under MIDI running status when Status repeats.
# All MIDI message numbers are hexadecimal (per source).

# UNRESOLVED: MMC (MIDI Machine Control) transport feedback messages are named but not byte-documented in source.

Variables

# Settable parameters exposed as continuous/enum values (already enumerated as actions above).
# None additional beyond the action parameters.

# UNRESOLVED: no standalone settable variables beyond the action parameter sets are documented separately in source.

Events

# Unsolicited notifications the device sends.
- id: scene_recall_notification
  notes: >
    When a Scene is recalled from the dLive screen, the unit transmits the Scene Recall
    (Bank + Program Change) message. See recall_scene action.

# UNRESOLVED: no other unsolicited event/notification messages documented in source.

Macros

# UNRESOLVED: no multi-step command sequences described explicitly in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures, or power-on
# sequencing requirements. Phantom power (48V) and preamp controls are present but no safety
# interlock text is documented in this protocol specification.

Notes

• Protocol nature: This is MIDI-over-TCP/IP. The transport is TCP; the message encoding is standard MIDI (Note On/Off, Control Change, NRPN, Pitchbend, Program Change, SysEx). There is no separate ASCII/string command set.
• SysEx Header: All SysEx messages share the header F0, 00, 00, 1A, 50, 10 (Allen & Heath manufacturer ID 00 00 1A, model bytes 50 10). Reply SysEx version bytes are MV=01 (major), mV=00 (minor).
• MIDI running status: dLive uses MIDI running status — a Status byte may be omitted when it repeats the previous message's Status. Omitted bytes are shown in [brackets] (e.g. [9N], [BN]) in command templates. Implementers must track the last Status byte.
• Channel selection scheme: Audio channel type is selected by offsetting the base MIDI channel N (set in Utility/Control/MIDI), and the audio channel number is selected via the note number CH:
  • Inputs 1-128: N=N, CH=00-7F
  • Mono Groups 1-62: N=N+1, CH=00-3D
  • Stereo Groups 1-31: N=N+1, CH=40-5E
  • Mono Aux 1-62: N=N+2, CH=00-3D
  • Stereo Aux 1-31: N=N+2, CH=40-5E
  • Mono Matrix 1-62: N=N+3, CH=00-3D
  • Stereo Matrix 1-31: N=N+3, CH=40-5E
  • Mono FX Send 1-16: N=N+4, CH=00-0F
  • Stereo FX Send 1-16: N=N+4, CH=10-1F
  • FX Return 1-16: N=N+4, CH=20-2F
  • Mains 1-6: N=N+4, CH=30-35
  • DCA 1-24: N=N+4, CH=36-4D
  • Mute Group 1-8: N=N+4, CH=4E-55
• Socket preamp numbering: Mixrack sockets 1-64 = MP 00-3F; Mixrack DX 1/2 = 40-5F; Mixrack DX 3/4 = 60-7F.
• Value encodings (from source tables):
  • Fader Level LV: +10dB=7F, 0dB=6B, -inf=00. LV = ((Gain+54)/64)*7F.
  • Preamp Gain GV: +60=7F, +5=00. GV = ((Gain-5)/55)*7F.
  • PEQ Frequency vv (20Hz-20kHz): vv = INT(127*((4608*LOG10(FREQUENCY/4)/LOG10(2))-10699)/45922).
  • PEQ Gain vv (-15..+15dB): vv = (GAIN+15)*126/30.
  • HPF Frequency vv: vv = INT(127*((4608*LOG10(FREQUENCY/4)/LOG10(2))-10699)/41314).
  • Colour: 00=Off,01=Red,02=Green,03=Yellow,04=Blue,05=Purple,06=Lt Blue,07=White.
• Two ports: Plain TCP 51325 (no encryption, no auth); TLS/SSL TCP 51327 (encryption + profile/password auth).
• Firmware: Source targets firmware V1.9 and later.

summary: "All 43 spec actions matched exactly to source command tokens with correct MIDI byte sequences and transport parameters verified. (12 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "MIDI transport (MMC) commands are named in source but no MMC byte sequences are documented; only the capability is listed."
- "Plain (non-TLS) port auth behaviour beyond \"no auth message\" is not detailed in source."
- "MMC (MIDI Machine Control) transport feedback messages are named but not byte-documented in source."
- "no standalone settable variables beyond the action parameter sets are documented separately in source."
- "no other unsolicited event/notification messages documented in source."
- "no multi-step command sequences described explicitly in source."
- "source contains no explicit safety warnings, interlock procedures, or power-on"
- "MIDI transport (MMC) commands listed as a capability (\"MIDI transport — MIDI Machine Control (MMC)\") but no MMC byte sequences are documented in this specification."
- "Authentication token format beyond \"UserProfile,UserPassword\" ASCII (UserProfile 00-1F) is not further specified; whether UserPassword has length/charset constraints is not stated."
- "Connection keepalive/idle-timeout behaviour not stated in source."
- "Maximum concurrent TCP client connections not stated in source."
- "PEQ \"Type\" restrictions per band (e.g. Shelf only on bands 0/3) documented but not enforced at spec-action level."
