As any manufacture will tell you most arranger players only use a small percentage of their arranger features, so while the Pegasus Wing is not as flexible as the larger organ range, it suits its target market, (Both in features and price) and being software based if demand could be proven then some of the features from the Sonic or OAS7 instruments could be added. (Unlike other arrangers it is not a static instrument)

Just out of curiosity, I checked it out on youtube. Couldn't find any demo's that show what the keyboard will do. All demo's were one song...one style?
