I use a computer sequencer. But notice that the new PSR1500 and PSR3000 have built-in Ethernet... that wasn't something that consumers were demanding - it's a way for Yamaha to make even more direct delivery of content to the keyboard. This'll probably end up being like the Apple music download thing: 99 cents a midi file or something like that. So we're not going to need a sequencer as much in the future except for original composition. Also, with color displays, Ethernet and everything else the newer PSR's are closer to actually being computers than ever before. So the Opn Labs (N)eko PC-based instrument concept never was that far off... we're probably getting there anyway.
