[. . . ] However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · Reorient or relocate the receiving antenna. · Increase the separation between the equipment and receiver. · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. [. . . ] Figure 6-2 It is used when you wish to emphaBPF (Band Pass Filter) size only a specific portion of the frequency range. (Figure 6-2) Use this when you want to emphasize just a specific region of the sound. For example, you can use Cutoff this to create a bandwidth-limited sound similar to sound heard from a small radio or a telephone. Frequency -12dB HPF ( ): -12dB/oct HPF (High Pass Filter) allows frequencies above the cutoff frequency to pass, and cuts the lower frequencies. Use this when Figure 6-3 you wish to make the sound thinHPF (High Pass Filter) ner. However if the cutoff frequency is raised excessively, the volume will decrease significantly. (Figure 6-3) For example you can use the HPF Frequency to purposely attenuate the low-freCutoff quency region of a sound that will be played together with other lowFilter oscillation frequency instruments, in order to If you raise the resonance to a high value, it will oscillate (produce a differentiate that sound from the sound) at the frequency specified by the cutoff frequency. filter oscillation ("self-oscillation") as a sound source. If the filter is oscillating, the "CUTOFF" parameter that normally adjusts the tone will instead control the pitch of the oscillation. Whistling is a typical example, and can be produced by adjusting the ADSR parameters of the filter EG. You can also try setting "FILTER EG INT" to a negative value. Another possibility is to select the MOD wheel or LFO 1/2 as a source in Virtual Patch, and use it to control "CUTOFF" as a destination.

FILTER EG -- SYNTH Here you can make settings for the filter EG, which applies time-variant change to the tone (Figure 7-1). Make these settings to specify the "shape" of the EG, and use the FILTER parameter "FILTER EG INT" to specify the amount of effect that the EG will have (p. 24). You can use AMP EG as a Virtual Patch source to modulate parameters other than volume. (p. 30) ATTACK [0. . . 127] Specifies the time from note-on (when the key is pressed) until the attack level (maximum value of the envelope) is reached. DECAY [0. . . 127] Specifies the time from when the attack level is reached until the sustain level (SUSTAIN) is reached. SUSTAIN [0. . . 127] Specifies the volume that will be maintained after the decay time has elapsed, as long as you continue holding the key. Figure 9-1 Level Note on RELEASE [0. . . 127] Specifies the time from note-off (when the key is released) until the level reaches 0. EG (Envelope Generator) To a significant extent, each sound has its own distinctive volume curve. For example when you play a note on a piano, the note begins at the maximum volume, and gradually diminishes. When you release your finger from the key, the sound will disappear quickly with a brief decay. Volume curves such as this are an important aspect of how we identify the sound of a specific instrument. This type of change also occurs in the tone and pitch, as well as in the volume. On a synthesizer, this type of change is produced by an EG. The microKORG has dedicated EGs for the filter and for the amp. However since these EGs can be used as Virtual Patch sources, you are also free to use them to vary the pitch or numerous other aspects of the sound. Some example settings are shown below. Piano Level Note on Note off EG RESET [OFF, ON] Specifies whether or not the EG will be reset for the second and subsequent note-on. If a new note is played before the previous note has finished its release stage, the envelope can either start over from zero, or continue from the current value. OFF ( ): The note will start from the current EG level.
