[Vm-dev] Mac OS Cocoa MIDI Plugin

[Eliot Miranda]

Hi All,

    recently the Cog VM on Mac OS X moved to Cocoa, the Objective-C API for
the platform, leaving behind the old Carbon C API.  There is some backward
compatibility support but it is gradually being deprecated by Apple.  One
victim is the MIDIPlugin which was written against a ComponentManager API
that, while Apple docs say is only deprecated, has actually disappeared.
Consequently the MIDIPlugin support (see
http://www.squeakvm.org/svn/squeak/branches/Cog/platforms/iOS/plugins/MIDIPlugin)
needs completely rewriting to use Cocoa APIs.  I've recently changed the
build so that the MIDIPlgin is built externally, which will make it easier
to work on; one doesn't need to build the entire VM, only the plugin.  I'm
looking for volunteers who
a) love music/know MIDI
b) are happy programming at the Objective-C level using command-line builds
and perhaps Xcode, but more immediately lldb for debugging.

If interested, reply to vm-dev and we can continue discussions there; there
are folks that can help with Mac OS support, but no one I know of that has
time to write this rather important plugin for multi-media.  It would be a
great shame to lose MIDI on Mac.
