I have just bought the psr740, and so far I have not noticed any boredom with the two bar loops. As I am an improvisational player, I appreciate monotonous stability(musical ingenuity vise) from my keyboard, and enjoy the challenge of adding my own stuff as I go along to make things interesting. I played the pa80 and the roland va 77, and the longer loops didn't do much for me.
Maybe its going to take time before I start feeling it. But on the other hand, i have had my psr2500 for ten years and have never been bored with the short loops, though, some musical styles in general bore me, but thats more taste, than anything else.
With the combo of xp60 and the 740, I am envisioning limitless possibilities for creating interesting live music. Even without the xp60 in the mix i find the 740 provides enough flexibility for improvisational playing. Though, having the xp60 by the side adds a whole new dimension to what i can slip into the improv mix, plus the extra 64 voices doesn't hurt either.
In conclusion I will incline towards Scott's perception of the two bar loops, adding in my perception, that I enjoy being challenged to create the next bar in the loop more interesting than the previous one.
