When I'm using RELEASE ECHO, it cancels the effects of the 3-BAND FX and the sounds from the SAMPLER section. Why?

[RELEASE ECHO] is a function that removes all effects applied by the unit from audio passing through the 3-band FX section. While holding down the [RELEASE] button, you can also prevent the effect from being canceled by performing the following actions.

■3-BAND FX ・Press the ISOLATE FX button and LEVER FX button to select an effect. ■SAMPLER ・Press the [FX SOURCE SMPLR] button to turn it off. ・If you're using the OVERDUB function, press the [OVERDUB/DELETE] button.
