Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

SampleTank crackle?

Is anyone else getting this, since the last IOS update? Whenever I launch SampleTank, it is accompanied by a horrible scratching noise. Not unlike the intro of a vinyl record that has been scratched to hell. Tried rebooting, etc. Have mailed devs.
I also had a 28 second movie, but it is apparently ‘not allowed’ on the grounds of being too big.

If it’s “not allowed” as an attachment, just upload it to Dropbox and put a link in the email.

Yeah, that did occur to me. But judging from the lack of comment, no one else is getting this. Oh dear...
Did test; no problems/crackles here. (12.9/latest)

Thanks anyway.
No crackles here 10.5 Pro latest

Curioser and curioser. I suppose the only thing to do is delete and reinstall. A job for the morrow.
@ikmultimedia supposedly, sampletank will be getting the AU treatment at some point in the future. I surely hope so!
Fixed! All it took was a lengthy, time-consuming, four attempt before successful, delete and restore purchases.
Sheesh! After all of that, I am glad to hear you got it worked out.

Thanks. It’s just irritating, as it came out of the blue for no reason that was obvious to me. One day working, then next unusable.
