yap, I know that at the end of the day MIDI is dealing with 1 byte at
time. I was wondering why there's a difference between 2 different piece
of code that generates MIDI (Pd and Hardware synth).
for example I just monitored (via USB) my Novation Circuit (a groovebox)
and Gmidimonitor receives messages 81 bytes long. with Pd as I said is
always 1 byte.
now my question would be, how is this possible?
I'm sure Circuit sends sysex 81 bytes long, so I know that this is
correct, but still I don't know why Pd doesn't allow something like that.
cheers,

MIDI is a serial protocol, individual bits running down a single line,
we now also have USB midi which is a little bit different than that
but usually that is abstracted for you.
The software monitor you're using likely groups these for you but in
reality you simply have a stream of individual bits on the hardware
line..
PD's object let you do bytes at a time instead of individual bits :)

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.
cheers,
Mario

I haven't tested in a while but I wrote an abstraction to take a
list, wrap it in the sysex start and end and output it as
individual bytes: https://github.com/x37v/pure_data

midi is a byte oriented protocol..

Hi,
do you guys know if there's a way to send a list of sysex
messages (or 1 complete message, let's say 8 bytes long)
rather then 1 byte per time?
if not, do you know if there's a particular reason why it's
not possible?
cheers,
Mario
