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.

How are you connecting the AN1x to your computer.
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.
