Hi I do lots of stuff with the Score Editor and used to have no trouble using Sonata font as my alternate music font until recently, and I'm wondering what gives. I just noticed it the other day for the first time. Logic 9 (latest version running on an Intel iMac using OS 10.6.8) runs very sluggishly (not just in the Score Editor) when I use Sonata and runs fine when I use the built-in fonts. It used to be fine while using Sonata. There are two things I've done on my iMac recently that may have initiated this behaviour: 1. I installed the latest version of Logic Pro back in December. (But I'm pretty sure I've worked on some projects that use Sonata font since then without any problems.) 2. I just installed the Finale 2012 demo and then purchased it. This is probably what did it, but I can't see why - because Finale's installers, which do involve several other music fonts, don't involve Sonata. I also have Jazz font installed (it gets installed by Finale's installers) but it's never worked properly with Logic (the wrong note heads are used by Logic, etc.). I thought I used to have Swing font installed too, but it seems to have gotten lost somehow, but I seem to remember that it used to work OK with Logic. I just never liked the way it looked. Anybody have any idea how I can fix it so that I can use Sonata font again?
