So the iPad is listening to the sounds made by the piano?
Does the iPad have socket for a 3.5 mm headset, or even a microphone?
Apple, so it might not or if it does it'll be a propritary connector
or on that 30 pin jobbie. Google is your friend, you're looking for a
way to get an audio signal into the iPad in place of its internal
microphone.
The P45 has a headphone out but plugging headphones in cuts the loud
speakers, so you'd have to find some way of splitting the signal from
the P45 to amp/speakers (aux in on your HiFi) and to the input of the
iPad.
The input to the iPad is also likely to be low (microphone) level so
you'll need to attenuate the headphone signal before feeding to the
iPad. Not difficult, a small 10 k ohmn trimmer potentiometr will do.
MIDI is a serial data stream, common on electronic musical
instruments but I'd be very suprised if an iPad supports it.
The P45 expects to connect to a USB host ie a PC. An iPad also
expects to connect to a USB host. Does Apple have support of OTG
cables? Even if it does will the error checking software take input
from USB?
