Selecting and Creating Tones
E-23
Description
(1) Synthesizer OSC1 Block
“OSC” is an abbreviation of “oscillator”, which is where a sound is actually produced. These two
synth OSC blocks creates sound using a sine wave, sawtooth wave, or other base waveform,
just like an analog synthesizer.
• Synth OSC: Generates the base sound and determines the pitch.
• Filter: Cuts some of the frequencies to adjust timbre.
• Amp: Adjusts volume.
• Three EG (envelope generators):
Control changes in pitch, timbre, volume, and other parameters over time.
The nearby illustration shows an example of a volume envelope.
(2) Synthesizer OSC2 Block
(3) PCM OSC1 Block
This block creates sound based on PCM sounds (same sound quality as sounds in the PCM
Tone category). For information about show the editable parameters of this block differ from
those for the OSC blocks above, see “Editable Parameters of Blocks (1) through (6)” (page
E-24).
(4) PCM OSC2 Block
(5) External Input Sound Block
Instead of an oscillator, this block creates sound based on sound input through the
Synthesizer’s
ck
MIC IN and INST IN jacks. The pitch change range of sound produced by
this block is limited.
(6) Noise Block
Instead of an oscillator, this block creates sound based on noise generated by a special noise
generator. The pitch of sound produced by this block cannot be edited.
(7) Total Block
This block combines signals (1) through (6) and sends the completed tone to the filters and
DSP (a type of effect).
(8) LFO1 Block
“LFO” is an abbreviation of “low-frequency oscillator”. The LFOs send waveform information to
each block that is used as the basis for modulation, tremolo and other reverb effects.
(9) LFO2 Block
(10) Controllers
Controllers include the keyboard, bender, and other controllers, as well as MIDI messages.
Control messages are sent to blocks (1) through (9) to control tones.
A virtual controller function can be used to freely configure combinations of controller types
(sources) and the parameters being controlled (destinations) to perform such actions as “pedal
depressed, change volume”.
