Maximum Polyphony*1*2 SGX-2: 100 voices*3
EP-1: 104 voices
HD-1: 140 voices
AL-1: 80 voices
CX-3: 200 voices
STR-1: 40 voices
MOD-7: 52 voices
MS-20EX: 40 voices
PolysixEX: 180 voices
*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.
*3: 100 dual-stereo notes (equivalent to 400 mono voices)
