You don't need any special recordings to achieve the effect, and I always leave the processor on. Mine has 3 buttons on the front: Injection Ratio (Normal/Theoretical); Listening Aperture (Narrow/Wide); On/Off. I leave them all on, all the time.
Try this: Put your speakers together, 2 inches apart, facing strait-forward for the time-being. Turn on the Holography and take a listen. After that, you can carefully toe the speakers in. The angle must be PERFECT, or you will get a lop-sided effect.
Of course, you don't need to use the synthesizer modes.
