i think it is a little shady of these companies to do that.... at least roland comes out with new products (although they withold their best sounds so you have to buy the roms) i really think they should make a rackmount version, maybe a two rack space and add the sampler and the extra orchestral board, plus begin Roland and emu style expansion. i dont know, but i havent heard much noise about yamahas plug in boards...they just dont seem to make a huge difference. i have the mo rack and this thing truly is awesome- my only gripe is no sampler, and you would have thought that with all of the current instruments dominating the market, even a modest sampler would have been sufficient. that really should'nt have been called a gripe, as it is more a "wishlist"... i love it!
