Aha ... sounds like an attack issue with the soundfont. You press a
key, there is an initial attack, the sample loops and reattacks.
- do the notes repeat if you play them staccato, i.e., key
on/off < the time seen for the repeated notes to trigger?
- Have you tried a different soundfont and/or patch and is the
behavior identical regardless?
