Sampler Question

does anyone use FXspansion Geist in X1? How well do they play together. I need a sampler that can actually sample. i have Emulator X2 but it doesnt work in win 7 64. (i'd have to upgrade to X3) but i bought the whole emulator library for Dimension so that wouldnt make much since. I also have Slice X from Imageline but it doesnt play well in X1 64bit. i have FL Studio Producer and FL Studio Mobile (on my ipod) & its probably the most stable DAW on the planet but i just prefer to make beats in X1. i do want to get Maschine because everyone uses it and im reading the horror storys with it and X1 and even it in standalone mode. I also read that BPM doesnt play well with X1. I wish the Bakers would improve on Beatscape and make it what it shoud be. Looks like its Geist or back to FL.
