Overview

The Multi-Camera Livestream Framework uses Dante audio networking for low-latency, high-quality audio transport from the MOTU 8PRE-ES interface to the Mac Studio running Ableton Live.

Key Components

Component Role Connection
MOTU 8PRE-ES Dante audio interface, clock master Ethernet → Dante switch
Dante Controller Audio routing software Mac Studio
Ableton Live Audio mixing, processing Mac Studio
Dante Virtual Soundcard (Optional) Software audio routing Mac Studio

Signal Flow

Microphones/Sources → MOTU 8PRE-ES → Dante Network → Mac Studio → Ableton Live → OBS

Hardware Setup

MOTU 8PRE-ES Physical Connections

  1. Power: Connect to UPS/power conditioner
  2. Ethernet: Connect to dedicated Dante switch (NOT main network)
  3. Audio Inputs:
    • Inputs 1-8: XLR microphone preamps

Network Requirements

  • Dedicated switch: Dante requires a dedicated gigabit switch
  • No WiFi: Never run Dante over WiFi
  • QoS: If sharing switch, enable QoS for Dante traffic

Dante Controller Configuration

Initial Setup

  1. Launch Dante Controller from Applications
  2. Wait for device discovery (typically 5-10 seconds)
  3. Verify MOTU 8PRE-ES appears in device list

Device Naming

Recommended naming format:

  • MOTU-MAIN - Primary MOTU interface
  • MAC-STUDIO - Mac Studio Dante receiver

Routing Matrix

The Dante Controller routing matrix shows transmitters (rows) and receivers (columns).

Basic Routing Example

Source (TX) Destination (RX) Channel
MOTU Ch 1 Mac Studio Ch 1 Host Mic
MOTU Ch 2 Mac Studio Ch 2 Guest Mic
   

MOTU 8PRE-ES Setup

Accessing MOTU Web Interface

  1. Open browser to MOTU’s IP address (check Dante Controller)
  2. Or use MOTU Discovery application
  3. Login with default credentials (check MOTU manual)

Sample Rate

  • Recommended: 48 kHz (broadcast standard)
  • Alternative: 44.1 kHz (if mixing with music production)

⚠️ All Dante devices on the network must use the same sample rate.

Clock Synchronization

Clock Master Setup

The MOTU 8PRE-ES should be the Dante clock master for the network.

In Dante Controller:

  1. Go to Device Config tab
  2. Select MOTU 8PRE-ES
  3. Set Preferred Master: ✓ Enable
  4. Set Clock Source: Internal

Verifying Clock Sync

In Dante Controller:

  • Blue clock icon = Clock master
  • Green indicator = Synced to master
  • Red indicator = Clock error (troubleshoot immediately)

Clock Priority Order

  1. MOTU 8PRE-ES (Primary master)
  2. Mac Studio DVS (Fallback if MOTU fails)

Audio Routing

Dante to Ableton Live

  1. Install Dante Virtual Soundcard
  2. Launch DVS and select channel count (e.g., 8x8)
  3. In Ableton Live Preferences:
    • Audio Device: Dante Virtual Soundcard
    • Input Config: Enable channels matching your routing

Option 2: Direct MOTU Routing

Integration with Ableton Live

Audio Preferences

Preferences → Audio
├── Driver Type: CoreAudio
├── Audio Device: Dante Virtual Soundcard (or MOTU)
├── Sample Rate: 48000 Hz
├── Buffer Size: 256 samples (recommended)
└── Input/Output Config: Enable required channels

Latency Settings

Buffer Size Latency Use Case
128 samples ~2.7ms Low-latency monitoring
256 samples ~5.3ms Balanced (recommended)
512 samples ~10.7ms High plugin load

Template Project Setup

Recommended tracks:

  • Host Mic (Dante 1)
  • Guest Mic (Dante 2)
  • Music/SFX (Dante 3-4)
  • Master Bus → Virtual Audio Cable → OBS

Troubleshooting

No Devices Visible in Dante Controller

Symptoms: Dante Controller shows no devices

Solutions:

  1. Check Ethernet cable connections
  2. Verify devices are on same network/subnet
  3. Check firewall settings (allow Dante Controller)
  4. Restart Dante Controller
  5. Power cycle MOTU 8PRE-ES

Audio Dropouts

Symptoms: Crackling, pops, gaps in audio

Solutions:

  1. Check clock sync status (Dante Controller)
  2. Increase buffer size in Ableton
  3. Check network switch for errors
  4. Reduce Dante latency setting if too aggressive
  5. Check CPU load on Mac Studio

Clock Sync Errors

Symptoms: Red clock indicator in Dante Controller

Solutions:

  1. Verify only one device is set as Preferred Master
  2. Check all devices are same sample rate
  3. Restart affected devices
  4. Check for network loops (spanning tree)

MOTU Not Detected

Symptoms: MOTU doesn’t appear in Dante Controller

Solutions:

  1. Power cycle MOTU (wait 30 seconds)
  2. Check Ethernet connection
  3. Update MOTU firmware
  4. Check Dante Controller version compatibility

High Latency

Symptoms: Noticeable delay in monitoring

Solutions:

  1. Reduce Dante latency (0.25ms if network allows)
  2. Reduce Ableton buffer size
  3. Disable unnecessary plugins
  4. Use direct monitoring on MOTU for performers

Quick Reference

Default Ports

  • Dante Primary: UDP 4440-4455
