PRIME CHORUS

Chain

Palette

This is BOSS’s proprietary chorus sound. It provides spaciousness and depth that were not previously obtainable.

Parameter

Value

Explanation

ON/OFF

OFF, ON

Turns this effect on/off.

RATE

0–100, BPM ŀ–Ō

Adjusts the rate of the chorus effect.

  • When set to BPM, the value of each parameter will be set according to the value of the “MASTER BPM” specified for each memory. This makes it easier to achieve effect sound settings that match the tempo of the song.
  • If, due to the tempo, the time is longer than the range of allowable settings, it is then synchronized to a period either 1/2 or 1/4 of that time.

DEPTH

0–100

Adjusts the depth of the chorus effect. To use this as a doubling effect, set this to “0”.

EFFECT LEVEL

0–100

Adjusts the volume of the effect sound.

PRE-DELAY

0.0 ms–40.0 ms

Adjusts the time needed for the effect sound to be output after the direct sound has been output. By setting a longer pre delay time, you can obtain an effect that sounds like more than one sound is being played at the same time (doubling effect).

WAVEFORM

TRI

Produces a typical chorus effect.

SINE

Produces a deeper sense of modulation.

LOW CUT

FLAT, 20.0 Hz–12.5 kHz

Sets the frequency at which the low cut filter begins to take effect. When “FLAT” is selected, the low cut filter has no effect.

HIGH CUT

20.0 Hz–12.5 kHz, FLAT

Sets the frequency at which the high cut filter begins to take effect. When FLAT is selected, the high cut filter has no effect.

SWEETNESS

0–100

Higher values produce a more enveloping sound.

BELL

0–100

Higher values produce a more brilliant sound.

OUTPUT MODE

MONO

This setting is appropriate for mono output.

STEREO

Produces a rich spaciousness when stereo output is used.

BPM

40–250

Adjusts the BPM value for each memory.

  • BPM (beats per minute) indicates the number of quarter note beats that occur each minute.
  • When you have an external MIDI device connected, the MASTER BPM synchronizes to the external MIDI devices tempo, making it impossible to set the MASTER BPM. To enable setting of the MASTER BPM, set “SYNC CLOCK” to “INTERNAL”.
