can i get a pointer to some code that does this? we need to do this for handling MIDI I/O in the hammerfall dsp driver. doing it from the interrupt handler causes audio dropouts because the midi i/o is so much slower. --p ------------------------------------------------------- This SF.net email is sponsored by: Microsoft Visual Studio.NET comprehensive development tool, built to increase your productivity.
