Chickensys does NOT support the PA engine (AFAIK) at this time. That includes PA1X, the PA80, 60 nor 50.
It DOES support Korg Triton Classic and Studio formats (but not Extreme yet, again AFAIK) and does an OK job of converting AKAI formats to Korg .pcg.
The PA has a different synth engine than the Triton - 4 OSC vs 2, and different effect busses (Master and inserts). The PA1X can read Triton format .pcg files and convert (as can PA80, etc), but is makes an educated guess as to what does not map correctly. That's not to say that the conversions are bad. They are not, but you cannot convert combi's only programs, and they don't quite sound the same as the original.
I would recommend that to get the best sounding patches, you should load them all into the PA1X and save them in internal format. Let the PA do the conversion.
