Another point. if you are just working with the RT data
Quote:
<SOURCE WAVE
FILE "D:\bb\RealTracks\Guitar, Electric, Rhythm LoungeFunkChorus Ev16 080 Direct Input\e10301.wav"
>

and you would like to change it to Direct Input to add your own FX,
it can be easily done by change the source file path, or you could just copy a section that needs another FX and paste the data to another track and set it to \Direct Input\ keeping the same riff without loosing it due to regenerate:
