About Maximum Polyphony
Maximum polyphony is the maximum number of notes that the internal sound
engine is capable of producing at a single time. If you try to play more than this
limit, the K61P automatically switches off older notes so that it can sound the
newer notes. If you exceed the limit, therefore, you may notice that notes are
dropping out or that they are ending prematurely.
The maximum available polyphony varies according to the number of oscillators
and effects used to produce the sound. The internal sound generator creates a
note using either one or two oscillators. Maximum available polyphony for 1-oscil-
lator sounds (such as the HARPSI/VIBES sounds) is 60 notes, while maximum
polyphony for 2-oscillator sounds (such as Grand Piano 1 [PIANO 1, Bank A] and
Grand Piano 2 [PIANO 2, Bank A]) is 30 notes. The reverb effect, when used,
counts as ten 1-oscillator notes, while the chorus counts as three.
