Ontime offset changes in ver 1.2

I have not been able to use version 1.2 because I have been making extensive use of Ontime Offset to make my piano parts play more human/realistic. After installing 1.2 I found that the offset values were treated differently. A typical chord with a -20% or so offset on the bottom note and perhaps a +5 offset on the top note is treated in version 1.2 as if it were a -80% and +20%. My plan is to begin all new songs with the new version and keep the 1.1 just to play the older scores so I don't have to rewrite all the note offsets so it's not a serious problem.

If there is a better way to soften and humanize piano parts than using offsets and lowering velocities on chords with more notes, I'd love to hear about it.

Thanks so much,
