[PD] sysex messages

[Mario Buoninfante]

Hi Marco,

I just wanna point out that I haven't got issues with Pd, no problem at
all. I can easily work with Sysex in various way and of course also the way
you described. mine was more a let's call it curiosity. also because I
think that the possibility to directly send a list to [midiout], and let Pd
deal with parsing, would be a faster process.

cheers,
Mario
