I never mentioned this in the past, because I used to think maybe it was an issue with my old computer (Windows XP, 4GB RAM). When I have Sforzando loaded into Vestige, notes played on the Sforzando keyboard should sound exactly the same when they are played back and exported by LMMS. There are other sound fonts in which the same issue occurs and there are many soundfonts which sound very good when LMMS plays them from Sforzando. So Vestige and/or LMMS are somehow changing (degrading) the tone of the audio signal being played by Sforzando inside Vestige. (For example, the Ivy Audio piano sounds superb when played on the Sforzando keyboard, inside Vestige - but it sounds horrible and much lower volume when LMMS plays it back or exports it as a wav file.) When I load Sforzando into Vestige, and then load certain SFZ files into Sforzando, the musical tones sound wonderful when played on the Sforzando keyboard, but it sounds terrible when played on the Vestige Instrument editor keyboard, or in the LMMS piano roll, or played back and exported as a wav file by LMMS. I've always noticed this, so I have finally decided to mention it and ask for a solution.
