ProKeys Sono as a Standalone Instrument

Standalone operation refers to using ProKeys Sono without a computer . To do this, an optional USB-type power supply or 9V, 500mA
center-positive power supply (sold separately) is required .
NOTE: While ProKeys Sono can receive power from two different power sources, the device only
requires one power source to operate. In other words, if one type of power supply is connected
(such as a USB-type power adapter), it is not necessary to connect the second type of power supply
(the 9V, 500mA adapter).
ProKeys Sono can function as a standalone instrument, providing seven premium voices, and a complete General MIDI (GM) sound
set . In addition to playing the built-in sounds, you can use the keyboard to trigger sounds on synthesizers or sound modules that are
connected to the MIDI Out jack on ProKeys Sono . By default, ProKeys Sono transmits MIDI data on channel one .
You can also use the Mic Gain, Instrument Gain, Direct Monitor and Voice Volume knobs in standalone mode to create a mix of your
keyboard, guitar and vocal performances .

ProKeys Sono Premium Voice Selection

The seven premium voices can be accessed via the Voice Select buttons on the top panel . Pressing one of these buttons
activates the corresponding sound .

Layer Mode

ProKeys Sono features a "Layer" Mode that allows you to play two of the built-in
premium voices in unison . To do this, press and hold one Voice Select button to
select the primary voice, followed by a second Voice Select button (the secondary
voice) .
You can exit layer mode by pressing a single Voice Select button .
Using Voice Controls in Layer Mode
When using Layer mode, the Voice Volume knob, Reverb On/Off button and Chorus
On/Off button all control the secondary voice, and have no effect on the primary
voice . Because of this, you must make Voice Volume, Reverb, and Chorus settings for
the primary voice before activating Layer mode . Here is an example of how to do this:
1 . Select the Grand Piano sound by pressing its Voice Select button .
Grand Piano will be the primary voice in this example .
2 . Turn the Voice Volume knob all the way up .
3 . Activate the Chorus and/or Reverb effect to apply either or both effects to the primary voice .
4 . Press and hold the Grand Piano Voice Select button, and then press the Strings Voice Select button .
5 . Activate the Chorus and/or Reverb effect to apply either or both effects to the secondary voice (Strings) .
6 . While playing the keyboard, slowly turn the Voice Volume knob down and up again . You will hear the secondary voice
(Strings) fade out and then fade back in, while the Grand Piano voice remains at its original volume .
ProKeys Sono 88 User Guide
Tip: When Layer mode is active, the
same "two-channel" MIDI information
is also transmitted to a connected
computer via USB. It is possible
to create layered sound effects by
using two software synthesizers in
place of an external MIDI synthesizer.
Please consult your software
application's manual for information
on configuration and MIDI routing.
