Hi again !

 

SysEx messages are dedicated to one synth, i.e. the sound patches, they can be hundred bytes long: SysEx message start - device brand and model - a bunch of voice data bytes - End of SysEx message. Any other instrument, software, or hardware gear (sequencer, merger ...) will ignore it.

 

Note messages are very short, which note, on or off, velocity and MIDI channel (1 to 16), recognized by any (yes, ANY) MIDI device. It was the original purpose of MIDI, to allow different instruments to "speak" together.

 

Controller messages are short too (controller number - value - channel). But... you can generate a nearly continuous data flow when tweaking "nervously" a mod wheel, or with the keys after touch for example.

 

Any MIDI device will "know" : note on - note off - channel - velocity - mod wheel and pitch bend data. Early MIDI synthesizers witout dynamic keyboard will ignore incoming velocity data and play at a constant level, a few will recognize velocity incoming data but not send any. Have a look at the "MIDI implementation chart" of your instruments to know exactly what is send, received, ignored or recognized, generally found at the end of the user manual. 

 

Hope that it helps...

 

Cheers.

J.F.

Yes, ‎I connect using a midi to USB adaptor. It's connected to in-out midi port of the An1x to USB port on my MacBook pro. The adaptor doesn't have a midi driver firmwire.

‎I reckon adaptor needs to be replaced. Any reccomendations? 

How do I set buffer sizes for sent and receive on Logic?

Also, I'm new to SysEx message. What is the implication of the SysEx midi message.  Spare me of my elementary question.

I suspect it's via a USB to MIDI adapter.

The trouble with many lower cost adapters is that they're not really very well coded.

All sorts of messages can get garbled, especially SysEx messages.

It's really worth while going for a quality adapter which comes with it's own MIDI driver firmware.

That could well solve your problem.

Also setting buffer sizes for send and receive within Logic may make a difference, especially again for SysEx messages.

Hi !

you can find here : https://midi.nonlineareducating.com/course/1198/midi-demystified

a whole lot of useful informations about MIDI. However if you understand how it works and how are structured MIDI messages it's useless to learn all the standard codes.

Cheers.

P.S. : The first "Monty Python-esque" video is a "must look" !

Wow! That's some tutorial right there! I'll read, study and break the info in bits and pieces.

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
