If you have Band-in-a-Box then you can navigate to Audio > Audio Driver/Settings and select the "Soft Synth Latency Adjust ..." button. The button automatically opens an explanation window. and loads the "ZZLATADJ.STY" style. This lets you adjust the latency setting for a non-DXI soft synth (e.g. GS-WaveTable Synth) by ear.

When you press the Start button, BB begins to playback the "ZZLATADJ.STY". "ZZLATADJ.STY" is a special style that contains audio and MIDI instruments that play quarter notes. The note of the MIDI track is a 5th higher than the note on the audio track.

While the notes are playing, adjust the latency on the spin control until it sounds like both notes are played in unison. Press start again. If the song starts with the tracks lined up right away then you are finished. If not, then this means you overshot or undershot the real latency by the length of a quarternote which is 500ms. (e.g.: If the MIDI begins exactly a quarter note early then the latency setting is now 500ms too high. If the audio is heard a quarter note early than the latency setting is still 500ms too low.)

Otherwise, you can search and load the ZZLATADJ.STY and adjust latency.
