Notice it does not change the only on the setting of the wheel itself, but also on the PITCH = ON", the Wheel at MAX, and the "WHEEL sound; that's because you just turned OFF the Wheel's set Range, and on the Pitch Modulation Sensitivity of RANGE = 99", leave these controls set, and try other effect. individual voices. voices. Other voices may be programmed to be sensi- 3. Set the MODULATION Wheel at maximum (notch in tive to pitch modulation. Set this wheel at maximum the wheel toward the back of the instrument). Then press [MODULATION WHEEL-RANGE] and use the [DATA ENTRY] slider to set different values from 0 (no modulation) to 99 (maximum modulation) while playing the keyboard. IF YOU DON'T HEAR THE MODULATION, BE SURE YOU'RE HOLDING DOWN THE KEYS FOR AT LEAST A FEW SECONDS. From this point, you can access other voices by pressing [MEMORY SELECT-INTERNAL] or [MEMORY SELECT-CARTRIDGE]. Then press each voice selector button, [1] through [32], and move the MODULATION WHEEL back and forth to test these voices. When you find a voice that sounds interesting with the pitch modulation, again press the [FUNCTION] button and try moving the [DATA ENTRY] slider to NOTE You will now be asked to turn on the MODULATION WHEEL effects and see how they can be used to alter the sound of different voices. change the modulation RANGE so you can hear how the wheel works at other than maximum available range. Selectively turn ON and try the modulation 1. Press [MODULATION WHEEL-PITCH] and then press the DATA ENTRY [ON] button to activate the pitch modulation effect. And set this wheel to take advantage of the maximum set modulation 5. Now that you've explored the Modulation Wheel PITCH modulation, try applying AMPLITUDE modulation. To work without confusing two types of modulation, you'll want to turn ON only one effect at a time. Therefore first turn OFF Pitch modulation by pressing [MODULATION WHEEL-PITCH] and then DATA ENTRY [OFF]. Then turn ON Amplitude modulation by pressing [MODULATION WHEEL-AMPLITUDE] and DATA ENTRY [ON]. Then move slider up or press this button to turn on the modulation Then move this slider up to achieve the maximum possible range of modulation And see this NOTE Applying AMPLITUDE modulation makes individual operators (voice sub-components) louder and softer, which can affect the volume or the tone or both, depending on the particular voice's internal structure. Once again, the voice must be programmed to be sensitive to the type of modulation. The voice we have been using as an example, "E.PIANO 1 " is sensitive to pitch modulation, but not to amplitude modulation, so the wheel will not have any effect on the voice with only amplitude modulation turned on. Try the other voices to find one which is sensitive to amplitude modulation; a saxophone voice would be a likely choice. 2. Play the keyboard and operate the MODULATION WHEEL. AT THIS POINT YOU MAY OR MAY NOT HEAR THE PITCH CHANGE IN A VIBRATO-LIKE FASHION. THERE REMAIN SEVERAL VARIABLES WHICH WE HAVE NOT YET DISCUSSED. The amount of pitch IMPORTANT NOTE At this point it is still possible that you won't hear any pitch modulation, even when the wheel is at maximum and the [MODULATION WHEEL-RANGE] is set to 99. This is because the voice itself must first have been programmed to be sensitive to pitch modulation. 6. In a similar fashion to step 5 above, turn OFF the [MODULATION WHEEL-AMPLITUDE] and turn ON the [MODULATION WHEEL- EG BIAS]. The EG bias does not utilize LFO modulation, but instead it varies the amplitude of any envelopes whose Modulation Sensitivity is programmed to a value greater than zero. As a result, you can use the MODULATION Wheel (or any modulation controller such as the
