Drum Machine insight?

[srcreamingroom]

I am a folk/hip-hop/experimental musician- I have been incorporating electronic sounding drums into my recorded music for years through VST instruments but am at a loss when performing live. Our recorded music is a combination of acoustic elements and digital elements (reminiscent of Portishead meets Gorrilaz, etc.) I would like to start creating and incorporating electronic sounding drums and sounds into our live set but I dont have any experience with Drum machines so I'm not sure what piece of equipment will satsify my needs, if anyone could offer any insight at all I would deeply appreciate it! Here is what I would like to be able to do:

- Create and manipulate drum beats in a live performance setting
- Access previously saved patterns/sequences
- Capability to load own samples
- In addition to quality drum sounds include some bass/synth sounds
- Ability to expand sample library
- Stand alone! Do not want to bring a computer on stage
- Intuitional for live performance use

Thank you in advance for any help you can offer!!
