Algorithms

This chapter will go through all Edit parameters in

the eight blocks and the Input and Output sections.

Mute mode

The eight effect blocks all have a number of different Mute

modes. They are located as the last parameter in the Edit list

of each block.

The idea is that you can decide how every single block

should react when you push the current blocks bypass key on

the front panel. Here is the description of what the five

modes will do when bypassed:

Mix 0%: Will mute the output of effect, and take direct

signal level up to 100% dry = 0% effect.

FX Out: Will mute the output of the effect, and

preserve direct signal level, according to Mix.

Output : Will mute both the output of the effect and the

direct signal.

FX In : Will mute the input of the effect, and preserve

the direct signal level. This enables the block

to finish an effect tail after being bypassed,

e.g. using this mute mode on a delay will let

the delay tail ring out even after being

bypassed or at preset change between two

presets with the same settings (only the

Delay, Reverb and Pitch has this mute mode).

Input: Will mute both the input of the effect and the

direct signal. Same basic function as FX In,

only this mode will also mute the direct

signal. (only the Delay, Reverb and Pitch have

this mute mode).

NOTE: Using the Input/Output mute modes will mean that

no signal passes through the current block when bypassed.

Gate

The basic idea about a Gate is that when the input signal

falls below a threshold set up by you, the Gate turns down

the signal by a certain number of dB’s, also set by you.

Example: You set the Threshold at -25dB and the Max.

damping at 30dB. When playing signal into the G-Force, the

Gate will not do anything, but when the input signal is lower

than -25dB (on the input meter) the Gate will start damping

to a maximum of 30dB (see the Noise Gate meter).

The speed of the damping is set by the Release rate

parameter (Rel.rate).

THE BLOCKS

In the In-section of the G-Force, you find the Noise Gate.

The gain reduction of the Noise Gate is displayed by the

LEDs below the Billboard.

The Noise Gate (including the Level parameter) is not

bypassed by the overall Bypass key. This means that the

Noise Gate will still be active even if you bypass all the

effects of the G-Force.

NOISE GATE

Mode

Using the mode selector, you can choose between Hard and

Soft Gating. Hard damps almost instantaneously when the

Input falls below the Threshold, while Soft damps gradually,

meaning damping very smooth and soft, without destroying

your sustain.

Threshold

When the input level falls below this Threshold, the Noise

Gate is activated.

Max. Damping

The maximum of dB’s that the Noise Gate can damp (also

called gain reduction), meaning if Max. Damping is set to 0

dB, the Noise gate will not damp at all. The damping/Gain

reduction is displayed on the meters below the Billboard.

Release rate

The Release rate sets the speed that the Noise Gate damps

with, meaning if the parameter is set to 100dB pr. second,

the Noise Gate will damp very quickly.

Level

This level control can be used for controlling the In Level of

the different presets. By setting the Level at -6dB, in all your

basic presets, you reserve a little extra level for your lead

presets. The Level parameter is also found in the Modifier

Matrix, and can therefore be controlled via pedal or MIDI.

Compressor

A Compressor is meant to reduce the dynamic content of the

input signal, and thereby keep a more constant level. When

the input signal exceeds the threshold, the Compressor starts

to reduce the signal according to the Ratio. The Ratio

1 2 ... 30 31 32 33 34 35 36 37 38 39 40 ... 59 60
