HiQNet Guide

Soundcraft mixers use HiQNet for remote control apps. This protocol has certain limitations which may prevent the app from working correctly.

Limitations

The Soundcraft Vi and Si series mixer does not allow remote control of all parameters via network. Mixing Station currently implements nearly all parameters which can be remote controlled. The following parameters are not controlable via network due to firmware limitations: - Mutegroups - FX - Routing - Pan for stereo sends (VI) - Limiter (VI) - Auto makeup gain (VI)

Mutegroups

It is not possible to access the mutegroups of the mixer - therefore the mute status might be shown incorrectly in the app.

Network Requirements

  • All devices must be in the same subnet
  • Broadcast must be enabled

Setup

For the basic setup guide see the getting started page. Additional configuration for the hiqnet addresses (this is a sample configuration and can be adjusted if required.)

Device HiQNet address Misc
Console Any other than 1337 Make sure not to use any access restrictions on the mixer
Android/iOS 1337 Make sure each instance of the app (including ViSi remote) has a different address!

You can also refer to the official soundcraft setup guide.

Troubleshooting

Mixer not connecting

Sometimes the network stack of the mixer crashes - this also happens with the official ipad app and is not related to mixing station. Only a reboot of the mixer can fix this issue.

  1. Make sure you can ping the IP address of the mixer from your mobile device. If this is not possible your network configuration is wrong.
  2. Make sure to fully close any other HiQNet apps (ViSi Remote) for at least one minute. This is required as otherwise the mixer won't connect to any other apps on the same device.
  3. If the mixer is detected by the app but the sync doesn't work make sure you've disabled any access restrictions on the mixer side.

Inside knowledge: How a connection is established

HiQNet is special in the way it establishes connections: Instead of the app connecting to a mixer, the mixer connects to the app. For this to work the app must be able to send broadcast requests to the mixer. Here is how the connection is established:

  1. App sends broadcast request for connection (udp)
  2. The mixer connects to the app (tcp)

Note: If the mixer does not respond to the message from step 1. for whatever reason (e.g. the network of the mixer crashed internaly) you won't be able to connect to the mixer.

During testing this happend randomly with the Si Performer and Expression series but is known to happen to any soundcraft mixer. I cannot change this behaviour since it's a bug in the mixers firmware.
