New to the forum, from France.

I'm looking for a cheap sampler to complement my setup (MC-303 not on the picture, DR-202, MC-09, TR-8, MX-1) and I've seen an SP-505 at a good price (100€ with a 128 memory card). I used to own an SP-202 10 years ago but I sold it because of the cheap sound and now I regret.
I do live techno and I'd like to know if it's possible to play samples (sequenced sounds and loops) and record at the same time with the SP-505. I don't want to stop and start all the time, otherwise it's not live anymore, or it makes things more complicated for MIDI sync.
Am I in the right direction or should I move along, and what sampler would you recommend then?
Thanks for the precious feedbacks!
