I don't hate anything about it other than the fact that being able to put 1gb of memory into it is overkill.
Even if you load all of the scats and other sounds available on Yamahas site then add 128 of your own TVN files you are only using about 25mb so what the hell can I do with all the free memory going to waste.
If you filled up the 1gb it would probably take hours to load a sound in anyway so any would be purchaser just buy 2 64mb dimms and have done with it.
