• Supports multiple inputs/outputs: 1x1 ... 8x8 (except 3x3).
• CPU safe.
• Fully utilize features of original AUNetSend audio plugin.

System requirements

• macOS 10.14 and above.
• 64-bit VST3 host application (DAW).

Troubleshooting

Bonjour Browser application can be used to inspect all AUNetSend providers. Plugin should be listed as "_apple-ausend.tcp." provider.

On new systems (macOS 10.13 and above) AUNetReceive may not connect to VST3NetSend via Bonjour discovery (seems IPv6 issue in AUNetReceive). To solve this problem enter IP-address manually.
