I need help identifying what they are
http://www.youtube.com/watch?v=wSUD8faTyr0
are they specified as portable samplers?

Hmm.. Besides Akai MPC 1000
What are the others
that has the same function
google is very shitty with me on this...

I've been searching and only roland and akai appears...

What I really need to know is
• What are they really called?
• Any other brands [model] ?

Thanks.

ONE LOVE
GOOD VIBES

 

Dunno if there's a reliable naming for these.

Here are some options for samplers small enough to fit in a laptop bag:
Apple iPad with Beatmaker 2 or MusicStudio or NanoStudio or whatever sampling app
Boss SP202, SP303
Roland MS1, SP404, SP555
Yamaha SU10, SU200, SU700
Zoom ST224
Korg MicroSampler (well, this one might be a little bit too long for a std laptop bag)
Korg Electribe SX (ESX1)
Elektron Octatrack


If by "portable" you mean "powered by batteries",
afaik the Boss/Roland SP series up to 404 (not 555)' the Yamaha SU10 and SU200, the Roland MS1 and the Korg MicroSampler all support battery operation.
I own some of the above, and I'd say the Korg Microsampler is one of the most sophisticated samplers.
If you prefer illuminated pads and mainly work with loops, you might be better off with an SP404 or SP555.
The Yamaha SU700 is another fantastic vintage machine, but sample storage is too limited for my taste.

What's nice about most samplers from the above list is that after powering on, you have instant access to all samples.
No manual loading and long waiting time before you can start to play.

 

Beat thang or however you spell it

 

Really depends on what your usage is. If you want to trigger some samples and FX on stage, the Roland SP404 is probably the easiest. The sequencer and sample editing is very limited and the pads are not velocity sensitive, but the FX are built for live use and it keeps it's samples in memory with no load time.

If you want to actually do music production on the go then a MPC500 would be way better. It's battery powered and usually the cheapest MPC you can find. You can make full tracks on it. I've seen them in Guitar Center for around $150.

Of course an ipad will do all this stuff and a whole lot more...no real knobs or pads though unless you bring extra gear.
