[Vm-dev] MIDI Plugins [was [squeak-dev] The Trunk: Sound-mt.53.mcz]

[Eliot Miranda]

Hi All (including some persons I know know MIDI in bcc),

    with Marcel working on MIDI I'm reminded that MIDI needs some love on
Linux and Mac.  My understanding is that there exists an alternative to the
libasound code on Linux.  It would be lovely to have this properly
integrated into the svn tree.  My understanding is that the Mac MIDI plugin
is using Carbon APIs, and hence we don't even have a MIDI plugin for the
64-bit Spur VM on Mac (the Mac Cog VMs all switched over to Cocoa precisely
because there is only marginal support for 64-bit apps under Carbon).  So
it would be great to have the Mac MIDI supoort updated to use newer APIs
and to have it work in both 32-bit and 64-bit VMs.  I'm asking for
volunteers; please help.
