Description
|
ShortMessages received via an external MIDI input port always return
0x90 in getStatus(). To get the real status byte, use getCommand() and
getChannel().
This can be verified with the DumpReceiver from the Java Sound Examples,
by modifying the switch cases which use getCommand() and getChannel() to
use (getStatus() & 0xF0) and (getStatus() & 0x0F).

J2SE v. 1.4.1 uses an optimized version of ShortMessage to reduce memory allocation time. This optimized class (com.sun.media.sound.FastShortMessage) does not override getStatus() so that the default getStatus() of javax.sound.midi.ShortMessage is returned.
Fixed in private workspace for Mantis.
