How did you make the song back in the 90's it was very hard to reinput the appegiator 
very complicated stuf...
An arpeggio is rather simple... can make it harder than simple, but the basic is simple...
to avoid #, use A4,C5,E5 as basechord and here you go
A4-C5-E5-A5-C5-E5-A5-C6-E5-A5-C6-E6-A5-C6-E6-A6
you can divide it in 4 seperate pieces:
A4-C5-E5-A5|C5-E5-A5-C6|E5-A5-C6-E6|A5-C6-E6-A6
see that the next note in every piece is just the logical follower? and that every piece starts with the next note of the chord?
Going back, is exactly the other way around

ok, but transposing that kind of arpeggio doesnt work everytime and then again, it's a basic arpeggio that usually works fine. but if you prefer a different type that isnt that predictable as going to the next note every 3 notes, you will have a hard time without using #notes
in the end, as low_profile said, they are harder to analyse, then to make
Was talkin' 'bout the basics... need to start somewhere without making it illogical
sorry meits
