</span>Heh, you're missing my point because there's a “time” component to both<br>
systems but that wasn't intended to be a connection. It's like the<br>
relationship between addresses in memory (pointers) and offsets.<br>
<br>
If you want to treat your midi notes as bare numbers that can be added<br>
and have no semantics of absolute pitch until you send them to a synth,<br>
be my guest. I would tend not to design a system that way, but if it<br>
works for you, more power to ya.<br>
<br>
I think I've offered all the help here that I have to give, and I don't<br>
feel I'm successfully getting my point across, so with respect, I'm<br>
going to retire from this discussion now. I'm supposed to be on<br>
vacation :-)<br>
