I think it all has to do with the instruments capability to handle data �and not midi speed......

31 thousand bytes per second��� fast !

While older synths with 5-pin din connectors for midi�inter-connectivity operate (and related gear/software) used 31.25 kbps, it is not required.

??? Of course it is required.

There were some attempts to use higher speed but it was not generally accepted.

Possibly, but moreover the problem is with OS overhead,�inefficient drivers, and try-to-do-everything-at-once-including-audio-and-video software.� If you take at Commodore 64 and write efficient asm code to do midi I/O, my guess is 31.25 kbps will work. But don't do that, get a modern microprocessor (even a relatively slow AVR-base arduino compared to new) and write midi I/O code at anywhere from 31.25 kpbs to speeds many times that. �

Maybe, but in the end you have to go down to MIDI speed, if you want to talk with common MIDI instruments.�

But many modern instruments started to use USB for MIDI transfer. Yamaha has their modification of FireWire protocol called m-Lan for audio and MIDI communication.
>having said that, I think there are ideas out there for successors to MIDI, but I haven't been following any of their progress.

From what I have seen there have been changes all along since 1985 still using MIDI.�


Yes, lot of changes, useful additions and improvements. Despite basic limited features it's still usable when used cleverly.�

Twenty years ago or so some people were saying MIDI was dead because audio processing�became accessible.

Sorry, but I don't see any connection between audio and MIDI. Two totally different attitudes...

However, from what I have seen MIDI has continued to grow/change/etc. and is still useful for those people who know how to use it for what they want.� Yes, there are still deficiencies, but there will always be issues with any technology.
