Happy New Year

I have a DU1E3 and had the first of the Yamaha tunings.  At that time my technician installed upgrade 2.20 CSP E3 V2.12. Since that upgrade it appears that the sustaining pedal doesn't occur as frequently as I remember or on songs that obviously call for it. My guestions are:  1) is there a program that I can install on my Windows PC that would allow me to look and see if the sustaining pedal is written into the midi file? and 2)is there an adjustment on the system for the sustaining pedal? and finally, could this all be in my imagination?

Cheers,
Joseph
