I connected a microphone to XW-P1, but it does not appear to work. Why?

The microphone only works in conjunction with certain tones, such as solo synth 9-9 (described below). The microphone is inactive while most other tones are in use.

Press the TONE button, then the SOLO SYNTH button. Select the 9th bank, 9th program (Basic&Mic IN). You should then be able to use the microphone. You can apply filter and effects to the sound from microphone input.

Also, keep in mind that the XW-P1 does not have sampling capabilities. This means you won't be able to use the microphone to digitize and store a sample, to use later as a playable tone. This is one of the main differences between the XW-G1 (which is capable of sampling) and the XW-P1.
