Having played with JMEtude for a while, it would appear that the docs are incomplete, and there's a couple of functions included that haven't been written up. These are:

getTempo()
getVolume()
getEndTime()
createMIDI()

And possibly others - argh! Would have made life easier if these had been included. Along with a 'what note is currently playing back' function. If anyone knows how to do this, i.e. get the pitch and duration of a note as it plays back using JMEtude, I would love to hear about it. Trying to write a basic basic vocal trainer, and need to compare current note value to an input FFT'd audio signal.
