LOL.  I would hate to see all currently existing midi gear made useless, though I can certainly see that as a possibility. In fact, with softsynths it has already happened!!!!!! Of course, there are still some people that prefer hardware synths. Of course, I have seen people in different forums go from softsynths TO hardware a well.

So, I agree; it may be a moot point.

However, I recommend separating midi as a vehicle of communication (all it a language, if you like) from the connection apparatus--the 5-pin din, current loop apparatus.

My usb-midi keyboard can communicate with vsts and other software via the usb connection. It does so using the "language" of midi (note on/off, CC, aftertouch, program change, etc.) Of course, it is based on 8 bits (e.g., 0x90 0x40 0x7F, 0xB0 0x0A 0x7F, etc.).

I suppose someone could come up with a 16-bit, 32-bit, 64-bit, or even higher version which might make the 8-bit system severely outdated. If they do, I would hope the make it reverse compatible if at all possible.

I love my dinosaurs!!!!

For what its worth, in my testing, I still used 8N1. In fact, until now it didn't occur to me to see if I could change that.

As for midi-over-lan and midi-over-internet, I have dabbled a little bit, but not much.  It seems to me that with internet latencies, to be effective, a system of time stamping and compensation is needed.  I haven't delved into that at all.

In any case, its nice to know that my arduino program works with both vsts and CZs. Perhaps I will hook up a midi connector directly so I can test different gear and different interfaces.  So far, I have only used 31.25 kpbs (8N1), but it might be interesting to have a device that tests 5-pin din, current loops at different speeds. My guess is that the range of tolerances for midi out (microprocessor dev board to hardware) would be different for midi in (hardware to microprocessor dev board). However, I would expect that anything other than 8N1 would fail totally.
