As stated in a previous topic, it’s not possible to access presets by iOS files app.
But I wish I can share my presets by folders as a walk-around.
I’m currently backing up presets from my old iPad to a newer one but it’s a pretty tedious job to move presets one by one.
Also, I’d be very appreciated for such feature, cuz it’ll be helpful when I share my GarageBand projects to my father, who shares music-making hobby with me.
I believe there will be more people who wants to do similar things.
Welcome anyone who wants to share presets by folder!
