CoreMidiModule

CoreMidiModule Publisher's Description:
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_3_1.rbp
* CoreMIDImodule_Control_3_1.rbp
* CoreMIDImodule_Virtual_Synth_3_1.rbp
* CoreMIDImodule_Delay_3_1.rbp

Limitations of the unregistered version:

* Distribution of projects or softwares contening CoreMIDImodule is NOT allowed.
* Limited number of MIDI send events (1500).
* Sending SysEx messages is not possible.
* Virtual Source and Destination disabled.
* Access denied to Dictionary-type or Data-type properties.
