The CVP also has three built in pedals. I use the center for tempo tap in, the left for accompaniment start/stop and the right for sustain. I use sustain a lot as I play full keyboard piano a lot. Tempo tap in is much more useful than it might seem because that’s how we typically set tempo, tapping your right foot, so it’s a very natural thing to do. I use it all the time, select a style, tap in the tempo I am thinking of for the song and the style starts correctly. The style start stop is used less but still useful, although it’s more difficult to use the left foot. I also have a 4th pedal plugged in (which you can do on a CVP). This is an expression pedal which I occasionally use for either rh volume or rh pitch bend on guitar or sax. This is my least used pedal.
Of course it’s easy to change pedal functions when you need to, like when using a pedal for drop in/drop out recording, but these 4 are my default set up.
