Re list of PR300S sounds...this is (or was) available at Noel Jones' Frog Music Press www.frogmusic.com ...then click on Rodgers Users Group, then click on FAQ, then click on PR300 keyboard list/chart...you will need Acrobat Reader if I remember correctly...you will see SOME of the 350+ sounds available at the touch of a key...if you want the complete list, suggest you visit your friendly local Rodgers dealer and ask to see the manual for the PR300S.
