Valve Force settings

Valve Force is an analog circuit that uses a 12AU7 (ECC82)

vacuum tube. It uses a single vacuum tube to deliver ste-

reo-in/stereo-out operation.

By generating the rich overtones and smooth distortion

that are typical of vacuum tubes, Valve Force produces

natural depth and a fat, driven tone. Valve Force also

includes a low-frequency enhancing “ultra boost” circuit.

You can apply Valve Force to the ﬁnal stage of a program,

combination, song, or sample playback to add rich over-

tones and smooth distortion, or use insert effects and mas-

ter effects (except for sample playback) in conjunction

with Valve Force to create your sound.

Valve Force settings for a program

1Press the Valve Force [ON/OFF] key to turn Valve

Force on. (The key will light.)

Placement

2Access the Program P9: Edit-Master Effect, VALVE

page.

3Use “Placement” to specify where you want to place

the Valve Force circuit.

If you set “Placement” to Final, the Valve Force circuit

will be placed after conversion to an analog signal by

the Main Output L/R output DAC (Digital Analog

Converter). After passing through Valve Force, the sig-

nal will be output to AUDIO OUTPUT L/MONO, R

and from the headphone jack.

If you set “Placement” to Insert (User 3/4 BUS), Valve

Force will be placed after conversion to an analog sig-

nal by the Indiv. Output 3/4 output DAC (Digital Ana-

log Converter). Bus 3/4 will be the input to Valve

Force, and will simultaneously be output from Individ-

ual 3/4.

After passing through Valve Force, the signal will be

converted back into digital form by the ADC (Analog

Digital Converter), and sent to the insert effects, master

effects, L/R, Individual 1/2, and 3/4 buses as speciﬁed

by the “Pan (CC#8)” “BUS Select,” “Send1,” and

“Send2” settings.

In/Out

You can’t use Valve Force on the L/R output from S/

P DIF, nor when resampling the L/R output in the

various modes.

4Specify the input/output destination for Valve Force.

If “Placement” = Final:

Valve Force will be inserted as the ﬁnal stage of the L/

R output.

If “Placement” = Insert (Use 3/4 BUS):

If you want to send the output of oscillator 1,2 to Valve

Force, set “BUS Select (IFX/Indiv.Out Assign)” to 3/

4(Tube), 3(Tube), or 4(Tube).

If you want to send the signal through an insert effect

and then into Valve Force, set “BUS Select (IFX/

Indiv.Out Assign)” to the insert effect, and set the

post-IFX “BUS Sel.” to 3/4(Tube), 3(Tube), or 4(Tube).

The output from Valve Force is assigned by the Pro-

gram P9: Edit-Master Effect, VALVE page “BUS Sel.”,

“Send1,” and “Send2” settings.

Use “BUS Sel.” to send the signal to the L/R bus,

insert effect IFX1–5 bus, or 1, 2 bus. “Send1” and

“Send2” adjust the send levels to the master effects.

Adjusting the Valve Force settings

5Adjust the Valve Force settings.

Select VALVE FORCE as the control function for the

front panel REALTIME CONTROLS knobs, or use the

Program P9: Edit-Master Effect, VALVE page to adjust

the settings.

Depending on the sound you are using, you may hear

noise if you turn the Valve Force knobs or edit Valve

Force parameters while sound is being produced.

Input Trim: adjusts the input level to Valve Force

Ultra Boost: adjusts the mix level to the ultra-boost

circuit located at the beginning of Valve

Force

Tube Gain: adjusts the vacuum tube gain

Output Level: adjusts the output level of Valve Force
