Alan,
I have a very strong opinion on this one. buy the Yamaha! The Roland doesn't have anywhere the features of the Yamaha. The Roland doesn't have a 16 track recordable sequencer, only playback of midi files and you can't program your own styles like the Yamaha does. The effects are much greater on the Yamaha. Unless you want to buy a Roland EM2000 for about $1295.00, you should buy the Yamaha 640 which sells for about $850.00. I have carried the roland EM 10 and up and have been very disapointed with their lack of features for their price range.
