RedNet 4 Dante Audio Interface

“`html

Product Specifications:

Compatible with: RedNet 4, RedNet MP8R, RedNet X2P, Red 4Pre,
Red 8Pre, and Red 16Line
MIDI Control Capability

Product Usage Instructions:

Prerequisites:

Before using MIDI control with the mentioned devices, ensure you
have MIDI controllers available.

Setup in RedNet Control:

MIDI Input Device: Select the MIDI input
device you want to receive MIDI messages from.
MIDI Output Device: Choose the output device
to send MIDI messages to.
MIDI Input Protocol: Set the input protocol
for receiving MIDI messages.
MIDI Output Protocol: Set the output protocol
for sending MIDI messages.
MIDI Channel Allocation: Assign a MIDI channel
to each unit for control.

Setup with Pro Tools:

Install RedNet Control on the same computer as Pro Tools.
Configure the following settings in RedNet Control:
- MIDI Input Device
- MIDI Output Device
- MIDI Input Protocol
- MIDI Output Protocol
- MIDI Channel Allocation for RedNet 4 / RedNet MP8R / RedNet
  X2P
Set up Pro Tools for PRE control:
Check RedNet Control under Setup > MIDI > Input
Devices.
In Setup > Peripherals, set Receive From and Send To as
RedNet Control in the Mic Preamps tab.
In Setup > I/O, assign mic pres to corresponding input
channels.

CC Protocol:

There are two CC protocol options available: Avid PRE (CC) – 3dB
steps and 1dB Step (CC) – 1dB steps. Use the provided format for CC
messages to control various functions of the mentioned units.

Frequently Asked Questions (FAQ):

Q: How many units can be connected for MIDI control?

A: You can connect up to nine units for MIDI control.

Q: What should be running first for best operation with Pro

Tools?

A: It is recommended that RedNet 4 / RedNet MP8R / RedNet X2P
and RedNet Control are running before launching Pro Tools.

MIDI Control for RedNet 4, RedNet MP8R, RedNet X2P, Red 4Pre, Red 8Pre and Red 16Line
FFFA001405-05 1

Prerequisites
· Supported Mac or Windows PC · RedNet 4, RedNet MP8R, RedNet X2P, Red 4Pre, Red 8Pre or Red 16Line hardware device · Compatible MIDI controller (see MIDI Controllers) · RedNet Control must be running to send and receive MIDI messages
MIDI Controllers
RedNet Control supports two different MIDI message types: · Controller Change (CC) · System Exclusive (SysEx) A compatible controller must be able to send user-programmable CC or SysEx messages. Since one of the CC protocol options available is that of the Avid PRE (formerly known as Digidesign PRE), the devices can be controlled from Pro Tools.
Setup in RedNet Control
There are five settings to consider: · MIDI Input Device · MIDI Output Device · MIDI Input Protocol · MIDI Output Protocol · MIDI Channel allocation In RedNet Control, select RedNet Control 2 and choose the Preferences sub menu.
2

The following options are available:
MIDI Input Device
“RedNet Control” is a software MIDI device that can receive MIDI messages from other software. All other MIDI input devices will be displayed here. The available devices will vary depending on what MIDI devices you have installed. Choose the input device you would like to receive MIDI messages from.
MIDI Output Device
“RedNet Control” is a software MIDI device that can send MIDI messages to other software. All other MIDI output devices will be displayed here. The available devices will vary depending on what MIDI devices you have installed. Choose the out device you would like to send MIDI messages to.
MIDI Input Protocol
Choose the input protocol RedNet Control shall receive.
MIDI Output Protocol
Choose the input protocol RedNet Control shall send.
MIDI Channel Allocation
By clicking on the “spanner” menu of any RedNet 4, RedNet MP8R, RedNet X2P, Red 4Pre, Red 8Pre or Red 16Line, a MIDI channel can be selected to which the unit will respond.
Note: · The default is “Off” · 16 channels are available, allowing a maximum of 16 independent device control paths · Two devices should not be set to the same MIDI channel · MIDI channel selection is saved with the computer, not the device. Therefore
when controlling the same unit from a different computer, the MIDI channel allocation may no longer be the same
3

Setup with Pro Tools

RedNet Control must be installed on the same computer as Pro Tools.

The following settings must be set within RedNet Control:

Setting MIDI Input Device MIDI Output Device MIDI Input Protocol MIDI Output Protocol RedNet 4 / RedNet MP8R / RedNet X2P MIDI Channel Allocation

Selection RedNet Control RedNet Control Avid Pre (CC) Avid Pre (CC) 116

Now set up Pro Tools for PRE control:
1. Click Setup > MIDI > Input Devices… and ensure the box next to RedNet Control is checked

2. Click Setup>Peripherals and click the Mic Preamps tab
4

Here you can connect up to nine units Choose Type = PRE “Receive From” and “Send To” must be set to “RedNet Control” and the same channel number set in RedNet Control.
3. Click Setup>I/O and click the Mic Preamps tab
Here, assign the mic pres to the corresponding input channels.
5

Setup with Pro Tools continued
4. Pro Tools will now control RedNet 4, RedNet MP8R, RedNet X2P, Red 4Pre, Red 8Pre and Red 16Line devices. Note, if you do not see the PRE controls at the top of the mixer window, click the “Mix Window View Selector” in the bottom left corner and select Mic Preamps

For best operation, it is recommended that RedNet 4 / RedNet MP8R / RedNet X2P and RedNet Control are running before Pro Tools is launched.

CC Protocol
There are two CC protocol options available: Avid PRE (CC) – 3dB steps. See Table A and B. 1dB Step (CC) – 1dB steps. See Table A and C.

CC messages take the format:

Ba cc vv

Where:

a is the zero-indexed MIDI channel number in hex

cc is the control number in hex

vv is the value in hex

For example: B4h 19h 0Fh will set the following:

RedNet 4 / RedNet MP8R / RedNet X2P unit on MIDI channel 5

Input gain of mic pre channel 2

6

to a value of 45dB
