Basic Operations Percussion sounds Example: 241 DRUM SET This tone assigns various percussion sounds to the keyboard. See the "Percussion Instrument List" on page A-5 for full details. Polyphony The term polyphony refers to the maximum number of notes you can play at the same time. The keyboard has 32-note polyphony, which includes the notes you play as well as the rhythms and auto-accompaniment patterns that are played by the keyboard. This means that when a rhythm or autoaccompaniment pattern is being played by the keyboard, the number of notes (polyphony) available for keyboard play is reduced. Also note that some of the tones offer only 16-note polyphony. NOTE • When rhythm or auto accompaniment is playing, the number of sounds simultaneously played is reduced. Using the Microphone Jack Connecting a commercially available microphone to the MIC IN jack makes it possible to sing along with the keyboard's built-in tunes. When connecting a microphone, be sure to first adjust the MIC VOLUME to a relatively low setting, and then adjust to the level you want after connecting. 1 Set the MIC VOLUME slider setting so it is on the "MIN" side. 2 Turn on the microphone's ON/OFF switch. 3 Use the MIC VOLUME slider to adjust microphone volume to the level you want.

Howling (Feedback Noise) Any of the following conditions can cause howling (feedback noise). • Covering the head of the microphone with your hand • Positioning the microphone too near to a speaker Should howling occur, try grasping the microphone further away from the head, and move away from any nearby speaker. Static Noise Fluorescent lighting can cause static noise in the microphone signal. When this happens, move away from the lighting you suspect may be causing the static.
