Sets of sounds for ASTRO.
A bank is a named set of sounds together with every sample those sounds need, all inside one file. It is how a set that plays here plays there. None of them come with the plugin: each is a file you download once, with an account, and import.
Make one yourself.
Sounds, samples and a cover.
The audio a sound depends on travels inside the bank rather than beside it, which is the whole reason the format exists. A hash covers the file end to end, so a truncated or edited bank is refused rather than half loaded.
Save it out of the plugin.
Anything you build in ASTRO can be saved into a bank of your own, named, reordered and handed to somebody else. A bank made on your installation stays yours to edit; one from someone else plays, and stays read only as a bank. Sealing one yourself keeps its contents closed in ordinary use, which is enough between friends.
A bank from this shelf is sealed differently: to a key that lives on the server and is leased to the account that has the bank, free or paid. It checks once with FL Connect when it arrives, and then runs for three months without asking again.
The longer version is on the ASTRO page, including what sealing a bank honestly buys and what it does not.
