I do not get it. I have a midi track imported and have selected the Surge XT plugin and in there i had selected the preset i loaded. As soon the playback reaches the end or at the beginning of that midi, it switches to the first default preset of Surge XT “Attacky” and not what i have set to.
If you copy them by hand, then sure, the PC will not be copied.
And “Acoustic Grand Piano” is by convention the type of sound associated with patch change zero (i.e. the first patch/preset/program) for General MIDI. So that’s your explanation right there.
