[PD-dev] Midi overflow, when receiving Song Position Pointer (os x)

[Jan Baumgart]

Hi there,

I'm experiencing a severe bug, when sending a Song Position Pointer 
message (0x242 0 0) to pd.

After sending just one SPP message to pd, the status window says:
"warning: MIDI timing FIFO overflowed".

When looking at the output of [midiin] I see "242 0 0 0" repeated endlessly.

The Song Position Pointer message belongs to the System Common Messages 
and has two data bytes. Pd seems to get confused with this message. 
Where is the third data byte coming from?

I'm running precompiled vanilla pd-0.44-3 from puckette's site on 32-bit 
intel mac (os x 10.6.8).


I have a related second question: Is there any way to receive midi 
realtime messages with pd on os x? I'm trying to receive Midi Beat Clock...


cheers,
Jan
