Performance synths withmore than 1 arp at once

[Exie]

To keep it clear: I need one arpeggio for bass on my left hand and another arp for lead on my right one

I'm searching for a relatively cheap and lightweight synth (not Motif or Fantom) to use in live performances. But there is a problem. Most of these synths allow you to use only 1 arpeggiator at once. The only exclusions I know are Korg Triton LE (it allows 2 at once AFAIK) & Karma (arps are its main feature), but I don't like Korgs too much.
Can your experience help me with choice?

KORG microX. In a word - awesome! I'm sure it will change your mind about KORG synths, although I can't imagine why you wouldn't like them in the first place. If you need more keys, there is always the X50. Or you could do it in software with something like EnergyXT and use a controller.

I haven't considered X series for my tasks, but I'll have.
I hate Korgs' combis change behaviour when they shut down all the notes. It is not a problem when you have several performing synths, but it is not my case. I hope X series don't suffer, but chances are little. But anyway, microX is tiny, it matches well to be co-synth. Thanks a lot!

The simple solution is not to use Combinations. I hardly ever do, except to set-up splits.
