Hi Mike,
are you sure? My PA800 has a sampler. Not part of the main manual. Sound editing, sampling etc has it's own manual which was on the rom disk. Wouldn't be surprised if some of the owners weren't even aware of it.
Sort of be a step backwards if they've dropped the sampler on the PA3X.
Correction on the Pa3X. It does NOT have an on board Sampler. Sequencer yes, Sampler... sorry.
Mike
