Note: Please reply to the list too. At the list there're people having
much more knowledge than I've got.
Hi Paul :)
* Have you used other GIG files too, but this particular piano sound?
* You are sure that you don't use an effect, e.g. a delay?
Pardon, I guess this is something you know yourself, it's just that I
want to except that the GIG is bad or an effect was disregard.
* Which version on what architecture of 64 Studio do you run? I
guess because of your hardware the architecture is amd64, but some
people prefer to run x86 even on 64-bit. Do you run 2.1 or
3.0-beta3? I don't know if anybody used QSampler with 3.0-beta3
;). I didn't use it and I only will make a test, if you are using
3.0-beta3 too, because I'm a little bit lazy ;). For 2.1
QSamplers's latency was fine on my machine and I never heard that
your trouble occurred by someone else. It might be an issue for
3.0-beta3. Dunno.
* Did you changed anything for your plain vanilla, OOB installation?
Do you know QSynth, resp. fluidsynth-dssi? 1. QSampler should work, we
should try to figure out what the problem is, but 2. if you need to
finish a song, you might like to use a "soundfont" instead of a GIG?!
Quasi as a band aid.
Best,
Ralf
