Put me off for a while, you can buy it complete (Ultimate or whatever its called) but its expensive that way- buy the basic synth in a sale then pick the FX up as you go along (interest free credit!) they are often in sales and once you have a few the upgrade price to ultimate gets cheaper....its not a bad system TBH...
Remember, all the presets (and there are a lot of them and cheap pre-set packs) let you use everything complete, you just cant edit some of the the FX until you buy them.
