I thought I had found a way round this, but I was wrong
iMini stores user patches in a file called ARTURIA_MY_PRESETS.minibank, which you can see if you go into the File Sharing section of iTunes and select iMini. The Tabletop version of iMini ('Tabletop iMini') uses a file of the same name, which can be found by going into File Sharing and selecting Tabletop.
You would think that you would be able to transfer your sounds from iMini to Tabletop iMini simply by replacing Tabletop iMini's .minibank file with iMini's one. However, this doesn't work. Even if I reboot my iPad then restart Tabletop, the patches in Tabletop iMini's 'My Presets' remain the same.
I had been hoping to get around iMini's Audiobus problems by recreating my sequences (composed in BeatMaker 2) in Tabletop, then ACPing them from there into BM2. But if I can't copy my patches, this isn't going to work.
If anyone from Arturia is reading this: please, we desperately need an update! iMini is a fantastic-sounding app, but what's the point if we can't actually use it with other music production apps?
