format 1 vs. 0 for speed....

[MUGSYŠ]

anyone have any experience in this?
I've been told that 0 uses less processor power...
if so, can I have an explanation...?
also, I've been using icq in a very unique way in the last little
while to beef up my "first times" in rooms.
Mabey I don't need to explain this....

evil bastige....

Depends a lot on the application. Ok ok, here goes... ;-)
Let's say that once loaded into the application, it usually does not make
much of a difference.

The loading process however *will* vary depending on the format.

Format 0 is much closer to the format used internally by playback engines, all
events are time-ordered. So a simple MIDI file player with no user
interaction would be very fast with format-0 (i.e. old Yamaha MDF players).

On the other hand, we usually expect to see data organized by tracks or at
least by MIDI channels. So in many instances, a format-0 file will actually be
slower to load because it must be split-by-channel.

Format-1 events are already organized as tracks so much closer to what you
expect to see on screen.

>if so, can I have an explanation...?

Sure can. ;-)

All in all, processor power required at playback time does not vary much for
either format; a slight bit more for format 1 but definitely not worth the
trouble of format 0.

For example, the ShowPlay MIDI player uses an internal format that
requires the same processing power for either format; only at load time is
there any (little) difference.
