Thanks for your response , it is very instructive. Here is what I hear you saying: 1.Soundfont generally make full use of the synthesis model described in the spec. I.e. if one tries to use the wave tables but fails to implement certain parts of the spec, the sounds won't be accurately reproduced. 2.Also, if I just sample fluidsynth output and apply an envelope it will not be an authentic reproduction of the sound (treble example for piano). Do I understand you correctly? Suppose we decided to go ahead with sampling fluidsynth output for the moment to get things started. Would using 5 wave tables (i.e. one per envelope phase) per pitch likely be a noticable improvement over using a single one per pitch? Do you happen to know whether there tends to be a correlation between wave tables and pitches in soundfonts? E.g. for a given soundfont it might be one wave table for every x pitches, or one table per pitch or several tables per pitch? Or is it simply more complex/less orderly than that and there is no rule of thumb describing the correlation between the number of wave tables for a given instrument and its pitches? The main reason we haven't seriously considered routing fluidsynth output into suppercollider are concerns that switching out sounds during a live performance would be a bit of a hassle if it either involved replugging connections in qjackctl and bringing up a new fluidsynth instance or typing something into a command line to load a new soundfont.
