Hi Alex,

thanks for your reply. I think that also using your abstraction Pd will 
spit out 1 byte per time (I didn't check it, but I assume that cause 
it's not an external in C).

about MIDI if I'm not wrong, bytes are grouped in accord with the type 
of message, ie Note on/off and CC are 3 bytes messages, channel pressure 
and program change are 2 bytes, sysex have variable length and so on. 
and I presume they're sent out in group.

in fact when I monitor MIDI messages coming for certain applications 
(I'm on Linux and I'm using Gmidimonitor) the console tells me the sysex 
size in bytes. so, with Pd the size is always 1 byte, but with other 
programming languages and softwares is variable and goes in accord with 
the sysex I generated.
