FWIW
Many Creative cards are hard coded to use 16/48 vs 16/44
so if one synth is using 44 kHz and another is using 48 kHz problems are likely to occur after recording.

If I recall correctly, setting the default bitrate in BiaB/RB to 48 kHz when using Creative hardware often helped .. but I haven't used Creative in years; it just stuck in my head as something to note.
Not sure it will help, but my first hunch.


I do not work here, but the benefits are still awesome
