3.3. Top panel general controls
Some important controls are on the top panel above the virtual keyboard:
3.3.1. Volume
The rotary control on the lower left side of the control panel is the master volume control
for the JUP-8 V4. Click and drag the knob to select a value within the range of +0 to -60
decibels (dB). Double-click the knob to reset the volume to its default value of -15.0 dB. The
VOLUME is saved with each patch. This parameter will also respond to incoming MIDI CC
#7 (MIDI volume) messages by default.
3.3.2. Master Tune
Click and drag on this control to adjust the tuning of the JUP-8 V4 to match other instruments
if necessary. At the 12 o'clock position, zero, it is in standard concert pitch (A440). At full
clockwise the tuning is A480, at full counterclockwise it is A400.
Double-click on the control to set it back to standard concert pitch (A=440 Hz).
3.3.3. Unison Detune
The JUP-8 V4 has the ability to stack multiple voices onto a single note to fatten the sound
when the VOICE MODE is in UNI mode. The UNISON DETUNE knob determines how much
the additional copies of the sound will be detuned from each other to make a fatter sound,
like voice doubling. You’ll hear the characteristic sound of two slightly out-of-tune notes
beating against each other. Low settings sound a bit like flanging, higher settings like fast
chorusing…in fact, this detuning is exactly what a digital chorus effect was designed to
emulate.
Double-click the UNISON DETUNE knob to set it to its default value of 0.125, or 1/8th of
a semitone. At the maximum setting (full clockwise), the voices may be as much as 1/2 a
semitone (50 cents) out of tune with each other. The more notes held on the keyboard at a
time, the fewer available unused voices there will be to stack and detune, so the detuning
effect diminishes.
UNISON DETUNE has no effect except in UNI mode, and has no effect if the Unison field in
Setting of the right sidebar set to 1. See VOICE ASSIGN [p.24] and SOLO [p.24] for more detail.
