I am testing the FX-13 effects patch with guitar. Input using a TS cable, output in stereo to 2 preamps. All my other patches are working fine, outputting in proper stereo. All my patches using the input with guitar also sound fine, outputting in stereo. However, when I switch to the FX-13 patch, everything is only in my left ear, aside from the reverb patch within FX-13. Is something screwed up with this patch?

Hi,

No nothing is screwed up! The patch is designed to utilize both mono and stereo signals:

- If you press and hold ‘Aux’ button and then press Key 1, you will enter Mono mode which sends the mono signal out both left and right outputs.
- If you press and hold ‘Aux’ button and then press Key 2, you will enter Stereo mode which sends the signals out their respective left and right outputs.
