[. . . ] If you experience any hearing loss or ringing in the ears, you should consult an audiologist. 4) This product should be located away from heat sources such as radiators, heat registers, or other products that produce heat. 5) The power-supply cord on this product should be unplugged from the outlet when left unused for a long period of time. 6) Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings. [. . . ] If you want to have a constant value of vibrato, 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 vibrato, and raising the Mod Wheel will add more vibrato. On the other hand, if the Mod Wheel parameter is set to -10, raising the Mod Wheel to the top will cancel out all vibrato. Mod Wheel (-99 to 99) This is the modulation amount of the Mod Wheel over the Pitch LFO's Level. A positive value raises the level when the Mod QuadraSynth Plus Piano Reference Manual 99 Editing Programs: Chapter 6 Wheel is moved up, and lowers the level when moved down. Negative settings of this parameter will decrease the output level of the PLFO as the Mod Wheel is raised. Since the output level of the PLFO 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 PLFO 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 vibrato from the PLFO. Aftertouch (-99 to 99) This is the modulation amount of Aftertouch over the Pitch LFO's Level. 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+. 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 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. Mod Wheel (-99 to 99) This is the modulation amount of the Mod Wheel over the Amp 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 ALFO as the Mod Wheel is raised. A negative setting of the Mod Wheel parameter will have no effect unless either the Aftertouch or the Level is set to raise the ALFO 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 ALFO. Aftertouch (-99 to 99) This is the modulation amount of Aftertouch over the Amp LFO's Level. A negative value will lower the amount of ALFO level as more Aftertouch is applied. Pitch Envelope Pitch Envelope (Page 1) Pitch Envelope can lead to dramatic effects, since it can cause the pitch of a single key to change drastically over time. It's typically used in special-effect synthesizer programs, but it may also be used more subtly in an acoustic program to simulate the characteristic of some instruments to go sharp on the initial attack, especially when played hard. J The following Pitch Envelope variables will have an effect only if the PITCH ENVELOPE DEPTH (on Page 2 of the PITCH function) is set to a value other than 0, or, if Pitch Envelope is a source in the MOD function. Attack (00 to 99) This is the amount of time the envelope will take until it reaches its maximum output level. Setting the Attack to 0 will make the 104 QuadraSynth Plus Piano Reference Manual Editing Programs: Chapter 6 pitch go to maximum immediately on hitting the key (if the Delay is also set to 0 in PENV Page 2--see below); a setting of 99 will result in a much slower attack, taking many seconds before the envelope gets to maximum. QuadraSynth Plus Piano Reference Manual 105 Editing Programs: Chapter 6 Decay & Sustain (00 to 99) As soon as the attack portion of the envelope finishes (when the level reaches maximum), the envelope will decay (decrease in level). The level it reaches is set by the Sustain control; how long it takes to get there is set by the Decay control. [. . . ] Many devices subdivide this clock signal internally for higher resolution (e. g. , 96 pulses per quarter note). Unlike a Start command, which re-starts a sequencer or drum machine from the beginning of a song each time it occurs, sending a continue message after stop will re-start units from where they were stopped. General MIDI General MIDI is an extension of the MIDI standard designed to meet the demands of the ever-growing multimedia industry, and to make simple the act of playing commercially produced MIDI sequences. The QuadraSynth Plus is a perfect General MIDI companion, since its Mix Mode uses 16 channels. Although many channels are commonly used for specific types of instruments (Example: Channel 1 is usually piano, channel 2 is usually bass, etc. ), channel 10 is always used for drums. [. . . ]
