That's an interesting observation thanks epsteinframe!
I intuitively knew, or lets say I had a gut feeling, that this is exactly what it would be like and have always resisted, good to know I was on the right lines.
I use Per|former - and I am very happy!!
Bought and sold ER-101/2 again very powerful, but shockingly awful to actually use in any meaningful way, unless you happen to like never being able to see your entire sequence and can hold everything in your memory, if you were good at playing Simon as a kid and can remember multiple instances of very long strings of numbers then it may suit you.
Bought ad sold Eloquencer, it's fine but I just didn't get on with it, especially the song mode, I believe it has had firmware updates since I used it so it may be different now.
Hope this helps :)
