Chapter 4 The Effects Explained

Delay Time Fine

Makes fine adjustments (in units of 1 ms) to the delay time.

Tap Time

(Used Only with Pan)

Adjusts the delay time of the right channel delay. This setting adjusts the right channel delay time relative to the left channel delay time, which is referenced as 100%.

Feedback

“Feedback” refers to the return of a delay signal back to the input. This parameter adjusts the amount of signal returned. Higher values increase the number of the delay repeats.

High Cut

The high-cut cuts the frequency component above the set frequency. This parameter adjusts the frequency where the high-cut starts working. When set to “Flat,” the high-cut does not affect the sound.

Delay Level

Adjusts the volume of the delay sound.

■R&D: Reverb & Delay

You can use REV. (p. 28) and DLY (p. 28) simultaneously.

■SOS: Sound On Sound

For more detailed instructions on using Sound On Sound, refer to p. 54.

Parameter	Value
SOSMode	HiQuality, LongTime
Quantize	Off, On
Tempo	60–160, BPM
Playback Level	0–100

SOSMode (Sound On Sound Mode)

Selects the recording mode.

HiQuality:

This mode gives priority to higher sound quality. You can record approximately 3 seconds of sound.

LongTime:

This mode gives priority to longer recording time. You can record approximately 6 seconds of sound.

Quantize

When Quantize is set to ON, the length of the loop is adjusted automatically according to the tempo set in “Tempo” (next item), even if the position at which recording was stopped is somewhat off.

Tempo

This sets the tempo that determines the length of the loop. The CTL pedal indicator flashes at the rate set here. When this is set to “BPM,” you can set the tempo with the Number 4 pedal (tap input).

Playback Level

Sets the volume level of the loop as it is played back.

PREAMP/SPEAKER

COSM technology is used to simulate the distinguishing bass amp characteristics in the “Preamp” section, and is used to simulate various speaker sizes and cabinet constructions in “Speaker Simulator.”
