Cakewalk speed problems

I've just heard from a list member that, playing retuned versions of
wamk280 (one of the Mozart pieces I've posted recently) through
Cakewalk, the pace of the piece is slower than the original.

I seem to remember hearing a similar lament from another list member
a few months back, also involving Cakewalk.

I do rearrange the MIDI clock definition, in order to achieve .001 sec
per clock pulse, but I'm PRETTY sure I'm doing it correctly; also, the
pieces play fine on, for example, Media Player, which comes with Win 95.
(and if Uncle Bill can get it right, surely the rest of us can as well!)

I don't have Cakewalk and haven't used it, but I'm guessing it's trying
to be "too clever" in some way that could possibly be turned off.
Does anybody know more about this?

Thanks!

Was that me? Dunno. I remember having trouble with something, could well
have been (an old version of) Cakewalk. The problem was that it
completely ignored the tempo in the file. Simple as that.

I think it was me. I don't know exactly what was
happening, but I will mention that saving the files
with cakewalk changed their tempos for real (IOW,
cake saved its idea of the tempo to the file).

Several list members have had trouble, when playing back my adaptive
tunings, with the speed of playback being too slow. Cakewalk was
the earliest reported program with a problem; then Audio Compositor
and sfront, and possibly others, showed similar behavior.

Thanks to Ed Borasky for identifying what may have been the problem!
The MIDI file specification is rather bizarre, IMHO, in how it handles
timing. There are two values, one fixed, the other potentially mutable
which are multiplied (or divided, I can never remember) to arrive at
the actual conversion between clock ticks and milliseconds. The first
is in the midi file header, the second comes in the form of tempo
meta-events.

I had read that tempo always defaults to 120 beats/min, and had omitted
an explicit tempo message on account of that. Apparently, that was a
MISTAKE; some programs assume 60 beats/min and/or other values.

I've modified the program to include an explicit tempo message in all
output files, and invite testing by anyone who has had a problem in the
past. Please e-mail me privately & request or send a sequence for
tuning; I'll send you back results (I'm still "estranged" from my web
site).
