Sibelius user John Glossenger got in touch with me to share his tips for using third party VST and Audio Units virtual instruments with Sibelius. He says:
Before I moved to Sibelius (from SONAR), I created about 2,000 presets for my various VSTs, such as Absynth, Pro53 and FM8. I ran into some problems while trying to use those VST presets in Sibelius. I wanted to use my VSTs quickly, without doing the official procedure, such as creating sound sets.
So I fumbled my way through the process, and learned a few things, and I thought I’d share my insights with the Sibelius community.
