Hi Eileen,
Yes, that would seem the easiest,but for the fact Composer produces a lead sheet with notation,lyrics, and chords I need for more unfamiliar songs on a much larger screen. I have hundreds of songs compiled through the years. Aside from these factors,I agree it is simpler to play them in house,so to speak. The drawbacks,however, are that the screen is smaller,hard to find and mute the lead instrument,chords not always there. On the other hand, I use the midi and audio player for vocal and familiar midis.
