Hairpin Playback Stuttering

[Gary Ewer]

My apologies if this is in a forum here somewhere... I've searched but can't find an answer.

I'm using Finale 2008a r.1 (Mac) on a G5 iMac (OS 10.5.6, 2.1 GHZ, 1.5 GB RAM)

Using Human Playback I am getting a stuttering playback. I've narrowed the problem down to the "Hairpins and Dynamics" setting in the HP settings. When I unclick this option, the playback is fine.

All instruments use a different channel. Any thoughts?
