[ENSEMBLE] button
Adds an ensemble-like effect to the 
sound.
Patch name

This opens the Patch Manager 
window.
*  This only works with the JUPITER-4 model on the SYSTEM-8.
[PATCH SELECT] buttons
Selects patches 1–16.
[HELP] button
Shows the help contents.
This is the same as “HELP” in the menu.

EDIT Screen
This screen is designed to look like the 
JUPITER-4. You can set the detailed 
parameters on this screen.
Keyboard area
Click on the keys to hear the sound. The corresponding keys react when MIDI 
messages are received.
The velocity changes depending on where you click the keys.
Click the keys up higher (closer to the control panel) for lower velocities down 
to the minimum, and click the keys down lower (further away from the control 
panel) for higher velocities up to the maximum.
Use the mouse wheel to shift the keyboard octave.
[CONDITION] knob
This simulates the slight degradation of the analog sound generator circuit over the passage of several decades, which might occur on the 
original JUPITER-4 model.
With this condition as the zero point, you can increase the value to simulate even more degradation for a warmer, more imprecise sound 
that’s characteristic of analog circuitry; or you can decrease the value to simulate a more ideal sound with less degradation over time.
