Thanks for replies! So I have another one question. Is it possible to "touch" new format before it's officially released? I'm developing a library to ...

I'm developing a library to work with MIDI. Now I want to implement parsing RPN/NRPNs. And right now it seems that I have no reliable way to parse NRP...

Yes, of course we can't interpret NRPN data. But if format is arbitrary, we can't even read data. For example, we see following bytes sequence: 99/xx ...

So the value of RPN/NRPN can be any, increment is always +1 unit of RPN, and decrement is -1, yes?

But if the format of NRPN can be totally arbitrary, is it possible to read them? For example, we can easily read custom meta events since meta events ...
