Sorry, I'm unable to give you any
MIDI/USB recommendations, perhaps
others can.
I use a couple of older internal cards
from E-MU that have external
interfaces with MIDI
ports.
E-MU 1616m.




Likewise with Logic, I'm not a Logic
user.
However, with most programs there's a
settings or options menu which may
allow the
settings for audio buffer sizes and
numbers and
perhaps MIDI too.
They can be quite important if you're

planning to send fairly large SysEx
messages,
e.g. bulk dumps.



Jeff has provided a good summary, but

just to add that there are a few
special MMA
defined SysEx messages, like 'GM
System On' that
are important for resetting
things.
And SysEx messages can be common
amongst a manufacturers hardware
offerings, e.g.
Yamaha's XG and Roland's GS
standards.
I have a forum over at

midi-tutor.proboards,com where I
explain MIDI in

some detail. Please feel free to
join, there's
no charge.





In addition, MIDI messages are divided
into eight main types.
The first byte of a message always has
the most significant bit set on, and
uses the
other three bits of the front half
of the
message to define the message
type.
So, in hexadecimal, shown as e.g. 8nH,
the '8' is the first four
bits the 'n' is
"another value" not
defined here, the 'H'
defines it as being hexadecimal.


Here's a summary of message types
from the MIDI specification:



8nH 1000nnnn 0kkkkkkk Note Off

0vvvvvvv vvvvvvv: note off
velocity





9nH 1001nnnn 0kkkkkkk Note On

0vvvvvvv vvvvvvv ≠ 0: velocity

vvvvvvv = 0: note off



AnH 1010nnnn 0kkkkkkk Polyphonic Key
Pressure (Aftertouch)

0vvvvvvv vvvvvvv: pressure
value



BnH 1011nnnn 0ccccccc Control Change

0vvvvvvv ccccccc: control #
(0-119)

vvvvvvv: control value

ccccccc = 120 thru 127: Reserved.





CnH 1100nnnn 0ppppppp Program Change

ppppppp: program number
(0-127)



DnH 1101nnnn 0vvvvvvv Channel Pressure
(Aftertouch)

vvvvvvv: pressure value



EnH 1110nnnn 0vvvvvvv Pitch Bend
Change LSB

0vvvvvvv Pitch Bend Change MSB





FnH 1111nnnn System Exclusive Message
