well, that does depend on the versions the triton has the Triton extreme, studio, classic, and le versions, and the Fantom has the classic, -S, and X versions. there is also the almighty Motif.
I would hope Big D responds to this, because he owns the Triton Extreme and had the Fantom S before he took it abck for the triton..
my question to you is, are we reffering to samples as patches, or samples as in actual records? if its actual records (sampling phrases, hits, etc.) then an MPC/SP sampler would be more ideal.
if its patches, it really doesnt ake a difference. my advice is to play with both machines for a while before making a choice.
the Proteus 2000 actually fits that m.o quite nicely, however... as does the Motif. realy, all that matters is your personal prefference, and if you are recording it as audio track by track, you can shape your sound in any way you like from the keyboard to pro tools, and it really wouldnt matter because all the "Big Three" (Triton, Motif, and Fantom) are excellent...
