Avantis MIDI TCP/IP Protocol

Print to PDF
  • Updated

 

ⓘ This protocol is for use with Avantis systems loaded with firmware version V2.0 and later.

 

TCP/IP control is available via the Network port on the Avantis mixer. Messages are sent using the MIDI format, as described in this article.

All MIDI message numbers shown in this specification are hexadecimal. Refer to the end of this article for tables of values for each of the parameters listed here.

Clients should be configured to use TCP port 51325.

 

MIDI Controllable Functions and Parameters:

MIDI Running Status

Avantis uses MIDI running status. This maximises MIDI transmission efficiency by allowing a MIDI message to be sent without its Status byte if the previous transmitted message had the same Status.

For example, turning Mute on for Inputs 1, 2 and 3 on MIDI channel 12:

Without running status – Full message string 9B, 00, 7F, 9B, 01, 7F, 9B, 02, 7F

With running status – Shorter message string 9B, 00, 7F, 01, 7F, 02, 7F

 

MIDI Channel Number

MIDI channel 1 to 16  =  0 to F

To extend the range of audio channels that can be controlled by MIDI messages the Avantis MIDI protocol uses a range of five MIDI channels to select between audio channel types.

The base MIDI channel N is the lowest channel of the range selected in Utility / Control / MIDI and cannot exceed 12 (B). The default is MIDI Channel 12 to 16.

 

The audio channel type is selected by offsetting the MIDI channel used in the message and the audio channel number is selected using the note number, as detailed in ‘Channel Selection’ below.

Scene Recall and MIDI transport use the base MIDI channel N.

 

Channel Selection

N  =  Base MIDI channel

CH  =  Channel Note number (refer to table)

Channels are selected using the MIDI channel number and Note number as follows:

Channel Type Base MIDI Channel (N) Channel Note Number(CH)
Inputs 1 to 96: N  =  N, 00 to 5F
Mono Groups 1 to 54: N  =  N + 1, 00 to 35
Stereo Groups 1 to 27: N  =  N + 1, 40 to 5A
Mono Aux 1 to 54: N  =  N + 2, 00 to 35
Stereo Aux 1 to 27: N  =  N + 2, 40 to 5A
Mono Matrix 1 to 54: N  =  N + 3, 00 to 35
Stereo Matrix 1 to 27: N  =  N + 3, 40 to 5A
Mono FX Send 1 to 12: N  =  N + 4, 00 to 0B
Stereo FX Send 1 to 12: N  =  N + 4, 10 to 1B
FX Return 1 to 12: N  =  N + 4, 20 to 2B
Mains 1 to 3: N  =  N + 4, 30 to 32
DCA 1 to 16: N  =  N + 4, 36 to 45
Mute Group 1 to 8: N  =  N + 4, 46 to 4D
Stereo UFX Send 1 to 8: N  =  N + 4, 56 to 5D
Stereo UFX Return 1 to 8: N  =  N + 4, 5E to 65

MIDI Strips

Custom MIDI messages

Fader strips can be assigned as MIDI Strips. There are 32 MIDI Strips available.

Each fader strip control can be assigned to transmit a custom MIDI message. This is used for controlling audio within a Digital Audio Workstation (DAW), another mixer, or parameters on external equipment such as effects devices. MIDI Strips can be named and coloured. They are stored within Scenes and can be made Safe from Scene recall.

The Template Shows load the following factory default messages for the MIDI Strip controls. These can be edited to suit your application. If required, they can be restored to default from within Scene 1 ‘Reset Settings’ in the Template Show. 

Function Parameter Description
Fader B1, 00, <VAR> to B1, 1F, <VAR> DAW track Level
Gain Rotary B2, 00, <VAR> to B2, 1F, <VAR>  
Pan Rotary B2, 20, <VAR> to B2, 3F, <VAR  
Sends Rotary B2, 40, <VAR> to B2, 5F, <VAR>  
Rotary Custom 1 B2, 60, <VAR> to B2, 7F, <VAR>  
Rotary Custom 2 B2, 60, <VAR> to B2, 7F, <VAR>  
Rotary Custom 3 B2, 60, <VAR> to B2, 7F, <VAR>  
Mute switch 91, 00, <VAR> to 91, 1F, <VAR> DAW track Mute
Mix switch 91, 20, <VAR> to 91, 3F, <VAR> DAW track Select
PAFL switch 91, 40, <VAR> to 91, 5F, <VAR> DAW track Solo

Where <VAR> is the value determined by the position of the control.

ⓘ Sel is not included as this is required to select the Processing screen for configuring the MIDI Strip.

ⓘ By default, Rotary Custom 2 and 3 use the same values as Rotary Custom 1.

Where  TC  transport control is:

    01  =  Stop

    02  =  Play

    04  =  Fast Forward

    05  =  Rewind

    06  =  Record

    09 =  Pause

    BN, 0C, Key      where Key = 00 to 0B (refer to table)

 

Set UFX Global Scale

Control Change message with control number 0D

    BN, 0D, Scale      where Scale = 00 to 01 (refer to table)

 

UFX Unit MIDI Channel Numbers 

M 

Optionally, a MIDI channel M per UFX unit may be assigned to control UFX parameters, configured either in Utility / MIDI or FX / UFX / Show Routing / MIDI Settings. These MIDI channels must not be within the range of MIDI channels configured for controlling the rest of the Avantis system (i.e., N through N + 4). Multiple UFX units may share the same MIDI channel M. 

Parameters are controlled by a CC message as described below. The mapping between the control number and the UFX parameter is configured for individual UFX units in FX / UFX / Show Routing / MIDI Settings.

 

Set UFX Unit Parameter 

CC message to UFX MIDI channel M and value vv, with control number nn configured by user. 

Select Channel Parameter Set Value
BM, nn, vv

Note that key and scale messages to local UFX unit are treated as UFX parameters. Thus, key and scale UFX parameters and Global Key / Scale do not share the same CC value. Instead, CC value is scaled to cover the full range of UFX parameters. Please refer to the examples below.
