The SP-300 contains sampled sounds, which have been recorded, analyzed and pro-
cessed from the actual sounds of the original musical instruments. These sounds
usually consist of one or more different samples reproduced by pressing a key. Each
sample is played back by a single oscillator. Sounds using just one oscillator have a
full polyphony of max. 60 voices, while sounds using two oscillators have a limited
polyphony of max. 30 notes. Sounds using more oscillators have a more limited
polyphony. When the number of notes exceeds the limit of the sound, some notes
will be stopped, so that the new ones can be heard.
Furthermore, when playing in Layer mode with more than two notes, the max.
polyphony depends on how many oscillators are used in total. Using the REVERB,
CHORUS further reduces the polyphony, respectively, by 10 and 3 notes.
