                     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

                         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

                       9nH 1001nnnn 0kkkkkkk Note On

                         0vvvvvvv vvvvvvv ≠ 0: velocity

                         vvvvvvv = 0: note off



                       AnH 1010nnnn 0kkkkkkk Polyphonic Key
                         Pressure (Aftertouch)

                       BnH 1011nnnn 0ccccccc Control Change

                         0vvvvvvv ccccccc: control #
 (0-119)

                         vvvvvvv: control value

                         ccccccc = 120 thru 127: Reserved.





                       CnH 1100nnnn 0ppppppp Program Change

                         vvvvvvv: pressure value
