I'm not familiar with the TAL sampler, but I presume that you are aware that you can just browse a SF2 Soundfont collection file (add them to your Refills folder) within Reason and load up an individual preset which will automatically load into an NN-XT device, and will give you a complete keyboard of notes (some sound fonts will sometimes have keyboard octave limits, eg bass) to play with?
If you're having trouble with the TAL for SF2 files, then this would be a solution for you.
