Thank you haha, yea the struggle is real with ios GB. Unfortunately, the keyboard doesn't record to GB as midi. Sampletank, when used as the input, records as actual audio. In order to fix mistakes I either have to try to "Frankenstein" another track together to try to fix the problem, but the only easy way is to completely re record the track, which is inconvenient.
I have hopes to someday have a computer with recording possibilities, as well as money to afford one. Bills come first, and for now, GB on iOS does the trick for non professional recording.
