REALbasic shareware module for the development of MIDI applications

CoreMIDImodule is a REALbasic shareware module for the development of MIDI applications on Mac OS X (Universal Binary and PowerPC Carbon Mach O). It is based on the Apple CoreMIDI architecture. All functions have been implemented and sometimes simplified (the MIDI packet list or the callback functions are "hidden" inside the module). This module comes with several REALbasic example projects including:

CoreMIDImodule_Test.rbp
CoreMIDImodule_Control.rbp
CoreMIDImodule_Virtual_Synth.rbp
CoreMIDImodule_Delay.rbp
REALbasic 2008 or later and Mac OS X 10.4 or later.
