I've never recorded with BandLab, but used it a lot for playback, and for a beginner, it's really good and very easy to use.

With regards to recording - I'm curious how this would work on a scale like 16 ins at a time. Dumping bits from the interface to disk as uncompressed .wav is trivial, on the browser I'm not sure how storage works. Would it have to upload to the cloud immediately?
