*1 A portion of the multicore processor in KRONOS is devoted to generating voices, and a separate 　 portion is devoted to generating effects. KRONOS dynamically allocates the voice processing power 　 between the engines as necessary. The quoted maximum numbers of voices apply when 100% of the voice 　processing power is devoted to a single engine.
*2 In rare cases, when a large number of processor-intensive effects are active simultaneously (for instance, more than 14 O-Verbs), polyphony may be slightly reduced.
*3 100 dual-stereo notes (It corresponds to 400 voices in the maximum.)
*4 The memory available for RAM samples will change based on the use of Expansion PCM libraries. About 1,129 MB is available when shipped from the factory (when loading the file named “PRELOAD.KSC”).
