Yes of course you can sample from any source into the Triton. Then you can rerecord that onto your DAT/MINIDISC etc and sample it again back into the Triton using the built in effects. Buy why bother with the extra work. Simply use effects the 1st time you record your signal from your origional source and if you still want to add more effects, then do as discussed above and continue sample and then record back again between the source and the Triton. It's not internal resampling but it is the next best thing at the moment I suppose.

I sure hope Korg listen to their users and add internal resampling in the next major upgrade. It is an essential function for any modern sampler!
