Email Oliver. He's a real sweetheart when it comes to support. If it's unavailable he'll at least let you know when it should be back. He is busy with standalone NL, though, so do be gentle.

Super cheap, but I have never seen it in stock sadly.

Fairly sure the adapter and software are the only way to access any of the update or backup functions. Nanoloop is really locked down. Luckily the adapter is super cheap and really useful.

Can Nanoloop Mono be updated via teensyboy? From my understanding, all the updates occur via sysex commands sent over midi which should make this possible. But the nlmidi tool via command line or web does not seem to work properly with it.
