All.
(the following is all with J's chords.)
some further clues from my testing _JAZZSWP.

1..if one looks in the style picker the tempo shows 140..
SO...
2..could it be that J's tempo of 62 is outside range and thus introducing
'artifacts' ?? it looks to me that such a big tempo gap might be an issue.
AND..
3..another interesting aspect IS when i demo (with J's chords)
at 140 the drums waveform seems to be more in line with what i
would expect...WHEREAS at tempo 62 the waveform graphic in bbtv is
not as pronounced !!

IN CONCLUSION...

i suspect that the choice of tempo might be the issue.
ie too much of a tempo gap tween 62 and 140 ??
ie posing a problem for the stretching algorithm ??

fwiw i normally on a style tempo of 140 in picker i would maybe add one quarter or deduct same from the style tempo...and test THAT as to sound quality. ie with JAZZSWP go no more than roughly 175 down to 105 ?? sometimes depending on the style i might be more adventurous...lol.


happiness.
