I have looked at the MusicPlayer to figure out how it uses BPM but I
don't get it.
How do I implement a BPM function (without the use of Apple
MusicPlayer) in my MIDI sequencer? I have a EditText box in my window
and I want to have BPM from 1-300, with 120 as defalt.
Use the MusicPlayer:)...
I'm not sure what the question is - BPM is a function of the Tempo map
- and the current tempo determines how many beats per minute a series
of events are being timed at - this in turn (in the case of the Music
Player for instance) determines how the sample based timeline of the
audio device we output to, is translated into a position in time map
(ie. for this sample number, how many seconds should I be through the
sequence, and then what beat does that translate to - both of those
values are determined by what tempo events you have in the seqeuence) -
this is what the music player and sequence handle for you.
