[sdiy] MIDI running status implementation - status bytes

[rsdio at sounds.wa.com]

and don't forget that System Real-Time is the exception to the rule.  
Although System Real-Time messages are technically Status Bytes, they  
do not interrupt Running Status. This is possible only because System  
Real-Time messages are only one byte in length, so they will never  
confuse the multi-byte state machine in your MIDI parser.
