E-19Basic OperationsThe term polyphony refers to the maximum number of notesyou can play at the same time. This piano has 64-notepolyphony, which includes the notes you play as well as therhythms and auto-accompaniment patterns that are playedby the piano. This means that when a rhythm or auto-accompaniment pattern is being played by the piano, thenumber of notes (polyphony) available for keyboard play isreduced. Also note that some of the tones provide only 32-note polyphony.A number of the tones that are available with this piano havebeen recorded and processed using a technique called digitalsampling. To ensure a high level of tonal quality, samples aretaken in the low, mid, and high ranges and then combined toprovide you with sounds that are amazingly close to theoriginals. You may notice very slight differences in volume orsound quality for some tones when you play them at differentpositions on the keyboard. This is an unavoidable result ofmultiple sampling, and it is not a sign of malfunction.This piano lets you use up to four parts simultaneously foryour performances. The parts are named Upper1, Upper2,Lower1, and Lower2, and the display shows the tonecurrently assigned to each.You can use the PART/(MIXER) button to display the tonesthat are assigned for each part (Upper1, Upper2, Lower1,Lower2). Each press of PART/(MIXER) button cycles throughthe parts in the sequence shown below. While a part isdisplayed, you can change the tone assigned to it (page E-18).With layer you can assign two different tones (a main toneand a layered tone) to the keyboard, both of which playwhenever you press a key.1. Select the main tone.2. Press the LAYER/(GROUP A/B) button to turnon tone layering. This causes the indicator lamp of the button tolight. The currently layered tone name appears on thedisplay. You can use the TONE buttons to changethe layered tone if you want.3. Select the layered tone.4. Now try playing something on the keyboard. Both tones are played at the same time.5. Press the LAYER/(GROUP A/B) button again tounlayer the tones and return the keyboard tonormal. This causes the indicator lamp of the button to goout. Layering is disabled during demo tune play and in theMusic Library Mode (while Music Library Mode lamp is lit). Layering is achieved by sounding Upper1 and Upper2 ofmixer Group A. This means you can use the mixer tochange the volume balance and stereo pan positionparameters for both the main tone and layered tone.
