Decent Pitch shifting/Octave doubler AUs (or pitch tracking synths) -- this exist on iOS yet?
There any AU (or combination of tools) around these days that could do what a 'octave doubler' guitar pedal would do (essentially, generate a monophonic tone an octave below a signal)? I don't have the cash to invest in Yonac stuff although I know there's a polyphonic pitch shifter in there. A pitch tracking synth would do the job I'm after really.
It's the only thing that I've not been able to bring into the digital realm yet (have a beat up old stomp box that cost me £25 and sounds maaaasive) and getting it done with software instruments would give me much more flexibility in audio routing.
