Working with Stacked or Split Programs
The Prophet Rev2 is bi-timbral, meaning that it can produce two 
different sounds/programs at the same time, either by stacking them, or 
by allowing you to split the keyboard and assign one sound to the upper 
section of the keyboard and a different sound to the lower section of the 
keyboard. 
The two layers are referred to as Layer A and Layer B. By default, Layer 
A is always active when you recall a program. If either the 
split a|b 
button or the stack a+b button is lit, then Layer B is also active. 
Each Layer can have different Effect, Unison, Arpeggiator, and 
Sequencer settings. This allows for some very interesting combinations 
of sounds.
As you scroll through various factory programs, you can tell which are 
stacked and which are split. On stacked sounds, the 
stack a+b button is 
lit. On split sounds, the split a|b button is lit. 
All factory programs have a “B” layer, even if that layer isn’t currently enabled. 
To hear Layer B in isolation, press the edit layer b button and disable stack or split (if 
active) by turning off the stack a+b btutton or split a|b button. Pressing edit layer b a 
second time enables Layer A again.
