18. Troubleshooting

Status shows "Offline"

  • Verify that the ESTË Live server is running
  • Check that the macOS firewall allows connections on port 3001
  • If using an external browser, verify you are on the same WiFi network

Musicians cannot connect

  1. Verify that the Mac and phones are on the same WiFi network
  2. Open the QR code dialog and check the IP address
  3. Try using the IP address instead of the hostname
  4. Check that the macOS firewall is not blocking port 3001:
    • System Preferences → Network → Firewall → Options → Allow incoming connections for ESTË Live
  5. Some mobile hotspots isolate devices from each other — use a dedicated WiFi router
  6. If the phone shows "ESTË needs a newer system to run", its browser is too old: update to iOS/iPadOS 16.2 or later, or install a current Chrome, Edge or Firefox

Crackling audio or dropouts

  • Increase the buffer size in settings (e.g., from 128 to 256 samples)
  • Close other applications using audio
  • Verify the audio interface is connected via direct USB (not a hub)
  • Check the sample rate (must match the interface setting)

Faders move but audio doesn't change

  • Check that the channel is not muted (M button)
  • Check that no other channel is in Solo (S button)
  • Verify that Panic is not active
  • Check the I/O mapping in settings

Meters don't move

  • If a yellow banner says "Microphone access is off", macOS is blocking the audio inputs. macOS treats every input as the microphone, audio interfaces included. Click Open System Settings, turn on ESTË Live under Privacy & Security → Microphone, then restart the app
  • Verify the audio interface is correctly selected in settings
  • Check the input channel mapping
  • Try reloading the page (F5 or Cmd+R in the browser)

Regions won't load

  • Verify that a tempo source is configured (Manual or MIDI File)
  • Check the CSV format (see section 12.1 for the expected format)
  • Verify that BPM is > 0
  • If using a MIDI source, make sure the MIDI file is loaded before the regions

App won't start

  • Verify system requirements (macOS 13.1 or later). On an older macOS the app doesn't open; with an outdated system WebKit it shows "ESTË needs a newer system" instead of the interface
  • Try deleting the ~/ESTE/.logs/ folder and restarting
  • Check Console.app for error messages
  • If the problem persists, delete ~/ESTE/ and restart (this recreates the configuration from scratch)
