*1: 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.
*2: 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.
