There are two footswitch inputs. These can be programmed for a wide variety of functions including fills, sustain, sostenuto, harmony/echo, harmonizer, multipad, ots changes, etc.

I am using a midi sustain unit plugged into the midi in of my PSR3000 in order to allow me to use the two footswitch inputs for other functions. So basically, I have three footswitches.

The dearth of footswitch inputs is a definite negative for the PSR3000.
