comment Detect piano notes and chords
@iankit: Likely much more money and research time has been spent on speech recognition than on music transcription. Speech is monophonic: Siri fails if multiple people try to speak into the same iPhone at the same time. Speech recognition is also much less sensitive to correct pitch analysis, just the slope trend is often enough.

comment How does a pipe organist deal with latency or delay?
Not sure about the latest iPads. But with previous iOS models, the electronics seemed to take about 1 video frame time (16.7mS) to verify and locate the touch, and the OS took about 1 frame time to deliver a touch event to the app's run loop. That's 33 mS. Then there's another app-to-audio-DAC buffering latency of (2 or 3) * 5.8 mS added to the response. So, on the order of 50 mS for any app, given the hardware available, even for Pro apps and perfect touch.

comment When does audio latency matter and not matter?
Even wired organ keyboards will have a big problem if the pipes are 30M+ away (100+ mS, close to a 16th note delay). How does the organist play in time with the choral conductor?

comment When does audio latency matter and not matter?
So, given your experience, it seems that not only drums, but simulated stringed instruments on any iPhone or iPad should also feel unacceptable to an experienced musician, assuming that the reports of around a 50 mS minimum latency from physical touch to audio output are correct. Same with "blown" virtual wind instruments, given around 15 to 17 mS of latency from mic to audio, (not counting DSP "blow" detection) minimum.
