There is a problem I've noticed that might be related to this. When I run the
synthesised drum sounds in Yoshimi Things like open Hi Hat, Crash Cymbal with a
long tail (but can be muted) get cut short by Rosegarden, compared with directly
driven by a keyboard. This means I can't vary the tail length. Those that have
a fixed length tail independent of note-off aren't bothered.
