How much control do I have over the vibration unit on the iPhone?
I am simulating a plucked string, it would be fantastic if I could get the iPhone to vibrate in accord with the sound.
so, a) is it possible to modulate the intensity of the vibration? b) is it possible to change the duration?
Would it be possible to mimic a sharp attack that falls off gradually over a period of a few seconds?
I am aware that in older versions of iOS, it was only possible to activate it. both duration and intensity were fixed: taking control on vibration
is this still the case? Or has it become more flexible?
