[. . . ] The two main controls of the amplifier module are the Level knob and the Pan knob. The Level knob is used to adjust the overall level of the amplifier while the Pan knob is used to locate the sound in the stereo field. The source can be positioned from left to right by turning the Pan knob clockwise and it will be centered when the knob is in its center position. The level of the sound is always modulated by the signal from the Amp Env module which is hard-wired to the Amp module. The level of the sound can also be modulated with the pitch signal from the Keyboard module, which is very handy when it is necessary to adjust the level of a sound across the overall range of the keyboard. When the inverter button next to the Kbd knob is in its off position, turning the Kbd knob clockwise will boost high notes and decrease the amplitude of low notes. Switching the inverter button to its on position will reverse the effect of the Kbd knob and boost low notes while decreasing the amplitude of high notes when turning the knob clockwise. When the Kbd knob is in its leftmost position, the amplitude of notes is the same across all the keyboard. Note that the middle C key (reference note) will always sound a the same level regardless of the position of the Kbd knob. The output signal from the LFO module can be used for adding a tremolo effect to the sound. The pan value can be modulated by signals from the LFO, the Amp Env and the Keyboard modules. The modulation signals will move the source relative to the source position determined by the settings of the Pan knob. Negative values of the modulation signal will move the source to the left of the source will positive values will move it toward the right. The amplitude of the motion is determined by the amplitude of the modulation signal multiplied by a gain factor controlled with the LFO, Kbd and Env knobs. In their leftmost position, the knobs will turn off their respective modulation source while it will be fully effective when the knob is completely turned to the right. Using the LFO module as a modulation source will move the signal from left to right at the frequency of the signal from the LFO module. Using the signal from the Env module as the modulation source will move the source to one side of the source and bring it back to its original position. Note that since the sign of the envelope signal is always the same, the source would need to be positioned completely to the left or to the right (Pan knob in its leftmost or rightmost position) in order for the source to sweep the entire space. Finally, the pitch signal from the keyboard will 4. 5 The Noise Generator Module 31 position notes depending on their pitch, low notes to the left and high notes to the right where the middle C is the reference note positioned at the location determined by the Pan knob. 4. 5 The Noise Generator Module The Noise module generates white noise and is followed by a -6dB/Oct low-pass filter used to adjust the frequency content of the noise. The Color knob is used to vary the cutoff frequency of the built-in low-pass filter. Turning this knob to the right increases this frequency and therefore increases the high frequency content of the noise until, in its rightmost position, the filter is fully opened. The F1/F2 knob controls the amount of noise sent to the Filter 1 and Filter 2 modules.
