A: Hi @RichardButler,

Thanks for the question. Currently we support a generation of maximum 5 minutes at a go. In future we may support even longer generations.

To generate a 10 minute longer tracks, here are multiple ways,
1. Turn on loop, and generate a loopable audio of around 15 seconds. Add it to arrangement, and repeat it 40 times. You can repeat as many times as you'd like. Export the arrangement.
2. Generate a 5 minute audio and add it to arrangement. Repeat it 2 times. Export the arrangement.

Hope this was helpful.
