Reply to Whats your choice of Sequencer/Sampler?

Hey all just wondering what you use in the way of sequencers/samplers/drum machines etc

Im just starting to look into FXpansion Geist. Link: http://www.fxpansion.com/index.php?page=120

Im aware of the power of Maschine with sequencing etc however ive never used it myself, im only going off what I have seen online.

What do you use and why?
