I own a TRITON, and PA80 does sound like a TRITON. But don't expect it to do the same things as TRITON does, like sampling, vocoder, MOSS board, expansion... and 8 effects processors, instead of 4.
yes, in the same manner don't expect TRITON to do things that PA-80 will do. like realtime styles performance, dual sequencers and pther performance goodies
