Thank you for your comment. You could mute the piano by turning down the volume, especially if you are playing vibes since you can add chords occasionally yourself while soloing. Sometimes I use the Rhodes sound instead (tap the treble clef for instrument options) although you might think the sound is a little like your vibes sound. Also you could try Gypsy Jazz (guitar choices).

One of the options in playback styles in the Jazz pack is Swing Two/Four where the first and last chorus is in two-feel.
