[. . . ] Analog Filter Module WARNING!! To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. 1-En CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. THE SYMBOLS ARE RULED BY UL STANDARDS (U. S. A. ) The lightning flash with arrowhead symbol , within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure; that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intented to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. [. . . ] Now, we're all set to experiment. (Auto-tuning) As the characteristic of analog circuitry, the heat makes the filter cut-off operation unstable. With the built-in Auto-tuning function, it self-adjusts the internal filter circuit optimal. and CC NUMBER keys simultaneously to start it (bars on LED flash while autotuning). Perform this auto-tuning when the unit is warmed up. 8 Chapter 2 Basic Operation Changing the sound 1. Passing the filter First, pass the input signal through the filter on the Stereo channel. This makes the sound of rhythm machine go through the filter. You now hear the change in sound already. CUTOFF change The CUTOFF knob changes the character of sound fed through the filter. Try rotating the CUTOFF knob, paying attention to the character of sound. Now press 4 POLE and 2 POLE keys alternatively while rotating the CUTOFF knob to hear the difference by the number of poles. FILTER TYPE selection FILTER TYPE, as the name implies, the type of filters is selected here by the combination of toggle switch position. Depending on the filter type selected by the combination of these switches, the way the sound change differs when the CUTOFF knob is rotated. Try selecting the different filter types while rotating the CUTOFF knob. Also, try them out with different pole selections. (Refer to Keywords in basic operation. ) 4. RESONANCE change The resonance effect gives the distinguish character of metallic sound. It should sound metallic as you rotate the knob. As the effect of RESONANCE changes largely on the position of CUTOFF knob, try changing the CUTOFF position when the effect of resonance is not so significant. Using the effects The MFC42 has the Phase Shifter and Distortion effects unit built-in. The phase shifter gives the sound the swirl or roll effect. The distortion effect distorts the sound. Turn the PHASE SHIFTER on and adjust the SPEED and DEPTH knobs. [. . . ] For example, if the MIDI channels are assigned as follows, the MIDI channel data on track16 can be received, but not the data on track15 as its MIDI channel is different. Record the setting on track The settings data is recorded at the beginning of sequence in Step Edit mode. On Track15, be sure that the now time is at the beginning of sequence. Press the STEP (F1) key to open the Step Edit screen. [. . . ]
