About the KRONOS’ PCM memory
“PCM”isanotherwayofsaying“samples.”The
KRONOShasseveraltypesofPCMbanks,as
describedbelow:ROM,EXs,UserSampleBanks,and
SamplingModedata

Lossless compression

alosslesscompressiontechnique.Thisyieldsamodest

Loading samples at startup
TheKRONOScanloadyourfavoritesamples

“Automaticallyloadingsampledata”onpage 164.
User sampling RAM capacity
TheKRONOScomeswith2GBofRAMpre‐installed;
theKRONOSXcomeswith3GBofRAM.
Approximately1GBofthisRAMisusedbythe
