As I type this out I think if the song is using a RealStyle, the app may try to download the style file and then prompt for the serial key. This unintended behavior would be a bug, which I can fix. If your device isn't online it might just work.

The iOS/Android apps also perform a special operation when saving on the device: If an appropriately named m4a render file is found, matching the song file name, it will be moved 'into' the SGU file, and the external m4a deleted.
Thanks for your reply. If I understand your reply correctly, if I follow your instructions, the BIAB Android app will play my SGU files - with real drums and realtracks - without Internet access (after being imported to the app). Is that correct?

If so, does the ability to change tempo and keys etc. work in the app like it does in the Win version? That's about all I'd need it to do for my purposes. Is there a video tutorial that shows the capabilities?

Your input is really appreciated because I'm on BIAB ver. 2022 and the Android app and the above described capability is what I've been yearning for so I can stay up with my Bluegrass chops without having to drag a computer around or create a zillion wav files at various speeds and in various keys. The Android app is my primary interest (since I'm doing what I need on BIAB Win ver 2022) and at this time the app is my motivator for upgrading to 2026.

If you personally are involved in the creation of the app and its capabilities, I'd like to take this moment to say THANK YOU!!!!
