Hi,
I'm nearly finished working on a Midi player that uses Quicktime to
play midi files. While this has the advantage of being relatively easy
to get going, I'd like to be able to offer the ability to switch off
channels, modify instruments and play the midi data through external
devices. I've been gradually checking out Core Midi with a view to
using it for the next version of my player.
Given that I known virtually nothing about Core Midi, the first thing
I would like to attempt is to replicate what I'm doing with Quicktime,
using Core Midi. I would like to be able to load a midi file, play it
through an AU where I can start, stop and control the rate ( including
reverse for rewind) and play the output through either a built in syth
or an external device.
So, could someone tell me the simplest way of getting something like
this working? What AUs should I be looking at?
Two more questions:
Is it possible to play a midi file (or later on, real time midi
messages) through the built in synth and an external device at the same
time?
With the Quicktime method I am currently using I always know where I
am in the sequence by just asking QT for the position. Would a simple
Core Midi set up like I described be able to do the same thing?
thanks for any help!
Peter
