Small sequencer & multisampler for live use

[Andy Keys]

Hi,

I love my Fantom X-7. It's been the heart of my home studio for three years, but I've found that live I'm playing it less and less, so it's harder to justify carting around 2 keyboards. So, I wondered if anyone can recommend something small & portable that has a sequencer capable of sending out SysEx messages as well as MIDI AND the ability to play multisamples over MIDI?

If I could find an alternative to hulking the X-7 around the country I could leave it permanently set up at home for recording and sequencing, but I need some of what it can do live.

Any ideas gratefully received.

Cheers
Andy
