I pulled my A-33 from EBAY.
Smart move Fran!
I still have my A-33 and keep it in reserve for possible: 'call to duty'.
In addition to getting the Pa50's classic live Korg sound, I really appreciate the micro-Arranger's flexible versatility:
1) microArranger alone thru headphones: personal entertainment, composing.
2) microArranger alone thru built in speakers: casual entertainment for a few friends. Grab and go 9 lb all in one take anywhere portability.
3) microArranger thru any home stereo system: casual entertainment for "house parties".
4) microArranger thru a small PA: light entertainment for small events & nursing home gigs
5) microArranger + Tyros 4: Weddings, Corp Parties, et al
6) microArranger + my Roland A-33 76 note keyboard Controller: trad. pianistic style playing venues.
Total weight of this combo (microArranger + A33): is only
27 lbs! As far as I know, there's no single 76 note arranger unit this light.
