Hi Si, The problem Hans and I were discussing relates to storing/loading sssad presets to/from disk. Again, it's not sssad's problem; it's a general issue with Pd. When the dsp service is delayed by long file accesses, dropouts happen.
That said, it's important to design sssad-using abstractions so that preset-changing doesn't cause discontinuities as well. For instance, use [line~] lags for changing parameters to smooth out the jump. It's certainly possible to "flick btween presets very quickly" with sssad-using abstractions; I do it all the time with [polywavesynth].
