The SonicCell looks interesting; they apparently started with the concept introduced by Ketron with the Midjay, but took it to another level: much better user interface and operative system, better sounds, better looks... the Midjay still has an edge thanks to the hard disk recording and the arranger section, but I am willing to bet that the SonicCell sales with outnumber the Midjay... let's say 10 to 1?
