The fact remains that, if you play an ARRANGER (rather than use it as an SMF player, which a WS could do just as easily, if not better), your left hand is constantly tied up playing the chords. This only leaves you a very limited time that you can rush over to the lever to do a bend, and most of the REALLY juicy stuff actually happens across chord boundaries. So, no go.

It's the main reason I miss my Chord Sequencer so much. After I lay the chords down the first time for Verse and Chorus (usually singing the lead), all I had to do was press PLAY on the CS, and the chords would repeat. But NOT the fills or variation choices, so I wasn't as locked in as an SMF would have made me. But off I could go and use the pitch bend like a crazy man!

I WANT MY CHORD SEQUENCER BACK!
