Hi Scott,
Actually, I'm willing to sacrifice Technics' composer for any comparable features in different keyboard (even though they might not be as userfriendly), my only problem with others (like Tyros), was that Tyros only have 4 patterns variations (which later on you pointed out, I can cheat a little bit and have more variations for me to play with).
Korg, yes..It's difficult, but I'm sure if there's a good tutorial out there (which i haven't found...I just downloaded one from tritonhaven..seems a bit easier than the user manual, but we'll see...). My opinion of Korg being "difficult" may be caused by me getting used to Technics' easy way of composing things...plus the un-helpful salesperson and Korg's paperweight (a.k.a the manual).
Ah...if money were no object....
