Re: [Bluemusic-users] Freezing issues

[Steven Y. <ste...@gm...>]

Hi Michael,

The resizing is supposed to be there as it is the length of the
generated sound, including things like extra reverb time that is a
result from mixer extra time, for example.

As for the second issue, we should definitely fix that.  There is a
TempoMapper class that is used when doing timeWarp calculations in the
blue.noteProcessor package.  What we should really do is reuse one of
the line widgets and make a tempo editor.  The support for parsing
t-statements from global score was always a temporary measure and we
should implement that first to have the tempo curve available.  We
should also then reuse the tempo editor to create a tempo instrument
so that instruments in the score can read tempo values as those are
readable.

I realize one can resize afterwards, and blue will indicate with an off-color which area of the object represents the actual length of the frozen sound, but this is kind of a pain, and can probably be fixed easily once the second issue is resolved.

It seems to still believe the sound is at 60 bpm, and repositions the playback absolutely to the beat where you set playback to begin. However, if bpm is 120 and I set playback to begin at the 10th beat, the sample should actually be played back five seconds in, not 10.  If you set playback to begin at a beat past the 60 bmp end of the sample, you'll get nothing.
