Re: MIDI files and streams

Sorry, I was a bit quick off the mark there.

I should rephrase that: The tool would have to write SMFs in some way 
that could be understood by an SMF interpreter, but the author ought to 
think simply in terms of seconds.

A highly interesting part of Phil's original post, which I hope I now 
understand better, is the following:

Phil said:

I looks to me as if Phil wants to create SMFs by recording the input 
from a MIDI input device, and that what he is saying here is that 
timestamps need to be supported not only by output devices, but also by 
input devices. Is that right?

That's something I'd also like to see!

best,

James
