I used to play just single instruments and my choice of songs to sing were minimal. Now I have a PSR 740 and boy, has it changed my life. I dont think I would even trade my arranger for a highly sophisticated non-arranger. It just wouldnt serve my purpose. All the claps and kudos I get for my music I owe it to my faithful 740 which has improved my presentation abilities and hey, what do yu know, it even patched up things between me and my girl when things were broken. She heard me sing and play. I was using the Vocal Harmonizer. I sang "All I have to do is dream" with Vocal Harmony and she just came and hugged me with teary eyes. With so many memories attached to my arranger, I don't think I would like to give it up for ANYTHING!!!
