Elektron Musical Instruments

Hi folks

Sorry for the slightly off topic post. If you don't want to start this
topic on the list, email me privately.

I want a hardware sequencer and I'm wondering which ones to look at. 
I'm really interested in creating/playing/jamming midi loops live.

I need:

Foot-pedal/Tap Tempo capability
Realtime Record with/without quantizing
Change patterns via keys/midi
Record takes on different tracks without stopping playback
Assign phrases to keys
Rock solid midi clock

I don't need:
Internal sounds/sampling/effects

Any suggestions?

Thanks,
