[. . . ] ALESIS QuadraSynth Plus Reference Manual Important Safety Instructions WARNING - When using this electric product, basic precautions should always be followed, including the following: 1) Read all the instructions before using the product. 2) Do not use this product near water - for example, near a bathtub, washbowl, kitchen sink, in a wet basement, or near a swimming pool, or the like. 3) This product, either alone or in combination with an amplifier and headphones or speakers, may be capable of producing sound levels that could cause permanent hearing loss. Do not operate for a long period of time at a high volume level or at a level that is uncomfortable. [. . . ] A positive value raises the level as more Aftertouch is applied. A negative value will lower the amount of PLFO level as more Aftertouch is applied. QuadraSynth Plus Piano Reference Manual 100 Editing Programs: Chapter 6 Filter LFO Filter LFO (Page 1) The Filter LFO is most often used to apply tremolo-like or "wahwah" effects to a sound. J The following Filter LFO variables will affect the sound only if the FILTER LFO DEPTH (on Page 2 of the FILTER function) is set to a value other than 0 , or, if Filter LFO is a source in the MOD function. Also note that the Filter LFO may have no effect if some other modulation source or setting has already pushed the filter cutoff frequency to its maximum. Wave (8 choices) The waveform determines the shape of the LFO. Use Quad Knob [1] to select either Sine, Triangle, Square, Up Sawtooth, Down Sawtooth, Random+-, Noise or Random+. For a graphic representation of these waveforms, see the diagram in the Wave section of the PLFO description on page 67. Speed (00 to 99) Quad Knob [2] controls the speed or rate of the LFO. For fast modulation, increase this value. For slower modulation, decrease this value. Delay (00 to 99) This is the amount of time that is to occur before the LFO fades in. Sometimes, it is desirable to have modulation come in a moment or two after a note has been played, rather than starting instantly. The higher the value, the slower the LFO fades in. Trigger (Mono, Poly, Key Mono, or Key Poly) The Trigger parameter determines how the LFO should be triggered, or started. There are four possible settings: Mono, Poly, Key Mono and Key Poly. A description of these settings is found in the Trigger section of the PLFO description on page 67. Filter LFO (Page 2) Level (00 to 99) This is the base output level of the Filter LFO. If you want to have a constant value of tremolo to the filter, even without using the Mod Wheel or Aftertouch, set LEVEL above 00. The Mod Wheel and Aftertouch will add or subtract from this base level. Example: If Level is set to 10 and the Mod Wheel parameter is set to 10, there will always be some filter tremolo, and raising the Mod Wheel will add more tremolo. On the other hand, if the Mod Wheel parameter is set to -10, raising the Mod Wheel to the top will cancel out all tremolo. QuadraSynth Plus Piano Reference Manual 101 Editing Programs: Chapter 6 Mod Wheel (-99 to 99) This parameter sets how much the Mod Wheel will increase or decrease the Filter LFO's Level. A positive value raises the level when the Mod Wheel is moved up, and lowers the level when moved down. Negative settings of this parameter will decrease the output level of the FLFO as the Mod Wheel is raised. Since the output level of the FLFO cannot be less than zero, a negative setting of the Mod Wheel parameter will have no effect unless either the Aftertouch or the Level is set to raise the FLFO output. If both the Level and Aftertouch are set to 00, and the Mod Wheel parameter is set to -99, the Mod Wheel will have no effect on the tremolo from the FLFO. Aftertouch (-99 to 99) This is the modulation amount of Aftertouch over the Filter LFO's Level. A positive value raises the level as more Aftertouch is applied. A negative value will lower the amount of FLFO level as more Aftertouch is applied. Amp LFO Amp LFO (Page 1) The Amp LFO is usually used to add tremolo to a sound. J The Amp LFO variables will have an effect only if the AMP LFO DEPTH (in the AMP function) is set to a value other than 0 , or, if Amp LFO is a source in the MOD function. Wave (8 choices) The waveform determines the shape of the LFO. Use Quad Knob [1] to select either Sine, Triangle, Square, Up Sawtooth, Down Sawtooth, Random+-, Noise or Random+. [. . . ] General MIDI also standardizes the placement of sound types in a sound device's memory bank. The QuadraSynth Plus' Preset 4 Bank is designed specifically for General MIDI, and organizes it sounds according to the General MIDI specification. This means, when a sequencer sends a MIDI program change message that is supposed to call up a particular sound, the correct sound on the QuadraSynth Plus will be called up, even if the composer of the sequence used a different sound device. The Programs in Preset Bank 4 use the General MIDI QuadraSynth Plus Piano Reference Manual 185 MIDI Supplement: Appendix B names (in some cases abreviated) with the letters GM added to indicate their are designed specifically for use in General MIDI mode. QuadraSynth Plus Piano Reference Manual 186 MIDI Supplement: Appendix B There are three MIDI registered parameters which the QuadraSynth plus will recognize in Mix Play Mode when General MIDI Mode is enabled.
