Noise or oscillation is heard
• When using an effect on the external audio source
being input from AUDIO INPUT 1 and 2,
oscillation may occur depending on the type of
effect or on the parameter settings. Please adjust
the input level, output level, and effect parameters.
You need to be particularly careful when using a
high-gain effect.
• After a sample edit has been executed, or after a
stereo sample has been recorded, a small noise
may be heard. This has no effect on the audio data
that was edited or sampled.
• When using the BPM/MIDI Sync function to
control the delay time of an effect, noise may occur
in the delay sound. This noise is due to
discontinuities in the delay sound, and is not a
malfunction.
Effects are not applied

Off,” or “MFX2 Off” settings checked? ........... ☞ p.125
• If you are in Combination, Sequencer, or Song Play

oscillator of the program used by the timbre/track
