Download two “sets” of .pcg files and “read me” docs. These are the LE88 Preloads, two versions:
LE88Fact.pcg – For Classic and Rack owners
LE88_TS.pcg – For Studio owners (Martin Hines)

Download the Factory Preload.pcg Data Map, which shows which memory locations/banks are occupied by the factory preload data and which are “open” (available for User data). The .pdf document lists all of the Triton models and the Korg Karma. (Martin Hines)

Triton Field Manual
Once upon a time, there was a guy who wondered "can I learn how to program this beast", looking anxiously on the Triton. After several months of practicing, ripping his hair off, and making all sorts of excuses not to leave Triton alone, this guy finally thought he had figured it out. But "why keep this experience to myself", he then thought... If everyone was to be taught the basics in sound-programming this would truly be a world of sounds... So, he managed to start with his next project - TritonFieldManual!! Download here
