I don't know if this is a clue or not, but I found that setting a value of 2 or more in the polyphony causes the last note to stick "on" when a render is completed.

The following par demonstrates what I'm talking about. Try running it with polyphony=1 and again polyphony=9. On my system p=1 ends fine. p=9 (or any other non-1 value) ends with a stuck note.

This par is a sped-up version of one of my favorites.

Bill,


I noticed a strange behavior in ver. 20.04p10. After loading the
following par. via the @  command, it plays as if polyphony was set to
"1". Regenerating either via "\" or loading a video mode, say SF7,
played it with polyphony = 9, as in the par. Repeatedly loading the
par showed the same behavior. It looks like ver20.04p10 loads the par
and either doesn't recognize the polyphony command or hardwires it to
"1".

Can anyone duplicate this?

For some reason that I haven't had a chance to discover yet, the
polyphony value in the PAR entry should be one more than the value being
used internal to Fractint.  Unfortunately, this will give you a bad
argument error when you try to run a PAR with polyphony=10 and the
default of one will be used.  I'll have to look into why we are doing
this.
