sounds, one in layer A and one in layer B. Layers are used to facilitate
split and stacked programs.
A split program maps the layer A sound to a key zone on the left side of
the split point and the layer B sound to the right. Six voices are allocated
to each key zone.
A stacked program maps both layers A and B to the entire keyboard, with
six voices allocated to each layer. So, when s
tack
a + B is on, the maxi-
mum polyphony is six. (At least two voices play with each keystroke.)
The voice activity LEDs indicate how the voices are being used.
If s

shortcut to switch quickly between two sounds without actually changing
programs.
Using the Display and “Soft” Controls
The Prophet 12’s more performance-oriented parameters are all acces-
sible via dedicated knobs and switches on the front panel, but there are
even more parameters available via the OLED display. For example,
there are fifteen knobs and switches in the Oscillator section. Editing
any of those controls reveals those parameters and their exact values—
as well as four additional oscillator parameters—in the display. Those
parameters are selected and tweaked using the four soft knobs and soft
keys located above and below the display. The soft knobs are detented
encoders and are great for dialing in specific values.
