Elements and Drum Keys Elements and Drum Keys are the smallest "building blocks" in the MOX6/MOX8 that comprise a Voice; in fact, only one Element or one Drum Key could be used to create a Voice. These small sound units can be built, enhanced and processed by a variety of traditional synthesizer parameters, such as Oscillator, Pitch, Filter, Amplitude, and LFO (shown below). OSC (Oscillator) Waveform (AWM2) LFO Low Frequency Oscillator Basic Structure Functional blocks Tone Generator block A/D Input block Sequencer block Arpeggio block Controller block Effect block Internal memory PITCH Controls the pitch of the sound. Pitch EG (Pitch Envelope Generator) FILTER Changes the tonal quality of the sound output from the PITCH unit. Filter EG (Filter Envelope Generator) AMP Controls the output level (amplitude) of the sound output from the FILTER unit. The signals are then sent at this level to the Effect block. Amplitude EG (Amplitude Envelope Generator) Oscillator This unit outputs the wave which determines the basic pitch. You can assign the waveform (or basic sound material) to each Element of a Normal Voice or each Key of a Drum Voice. In the case of a Normal Voice, you can set the note range for the Element (the range of notes on the keyboard over which the Element will sound) as well as the velocity response (the range of note velocities within which the Element will sound). In addition, the XA related parameters of this unit can be set. Each waveform consists of sample(s) created by recording the sound of the actual instrument and assigning appropriate keyboard and velocity settings. Oscillator related parameters can be set in the Oscillator display (pages 38 and 48). Reference Voice mode Performance mode Song mode Pattern mode Mixing mode Master mode Remote mode Utility mode Quick setup File mode Appendix MIDI Pitch This unit controls the pitch of the sound (wave) output from the Oscillator. In the case of a Normal Voice, you can detune separate Elements, apply Pitch Scaling and so on. Also, by setting the PEG (Pitch Envelope Generator), you can control how the pitch changes over time. Pitch related parameters can be set in the PITCH display (page 39) of the Voice Element Edit. Note that the Pitch related parameters of a Drum Voice can be set in the PITCH display (page 49) of Drum Voice Key Edit. Filter This unit modifies the tone of the sound output from Pitch by cutting the output of a specific frequency portion of the sound. Also, by setting the FEG (Filter Envelope Generator), you can control how the Cutoff Frequency of the Filter changes over time. Filter related parameters can be set in the FILTER display (pages 41 and 50) of Voice Element Edit or Drum Voice Key Edit. Amplitude This unit controls the output level (amplitude) of the sound output from the Filter block. The signals are then sent at this level to the Effect block. Also, by setting the AEG (Amplitude Envelope Generator), you can control how the volume changes over time. Amplitude related parameters can be set in the AMP display (pages 43 and 50) of Voice Element Edit or Drum Voice Key Edit. LFO (Low Frequency Oscillator) As its name suggests, the LFO produces a wave of a low frequency. These waves can be used to vary the pitch, filter or amplitude of each Element to create effects such as vibrato, wah and tremolo. LFO can be set independently for each Element; it can also be set globally for all Elements. LFO related parameters can be set in the LFO display (pages 33 and 45) of Voice Common Edit or Voice Element Edit. MOX6/MOX8 Reference Manual 6
