3. Introduction
Hi,
I’m a student
I live in INDIA
I started this course because I am interested
in pursuing music production as a career
later in life
4. What is a synthesizer?
First a short description of what a
synthesizer is. A synthesizer is an electronic
musical instrument designed to produce
artificially generated sound, using
techniques such as additive, subtractive,
frequency modulation, physical modeling or
phase modulation synthesis to create
sounds.
5. Oscillator
An oscillator is something that generates the basic
waveform that serves as raw material for the
creation of sound.
It has several waveforms, sine, sawtooth, triangle
and square, and each gives a sound type quirky
and different to each other, given the different
harmonic content they have.
6. Filter
Filters pass certain frequencies of the basic
waveform and certain other blocks. It is one of the
main parts of the synthesizer, not only because the
sound sculptures are "softening" the basic
waveform, but because it contributes to the
characteristic sound of each synth, even more than
the oscillators.
Generally synthesizers mean that you can change
the filters in multi-mode, which select what type of
filter it is: low pass, high pass, band pass, or band
stop. You can also select the filter slope, which
gives you more tonal options.
7. Amplifier
Amplifiers are used to control the signal level with
the passage of time. The amplifier is equipped with
a module known as an envelope, which is divided
into several elements that facilitate the control of
the level to the input phases, the middle and the
end of their sound. Simple synthesizers typically
provide simple envelope, which is used to control
the oscillator (and filters) over time. Complex
synthesizers can integrate multiple enclosures.
8. Envelope
Envelopes serve to modulate the intensity or level
of a parameter. There is an envelope allocated to
the volume of sound and another assigned to the
filter cutoff frequency. Among these two envelopes
are enough possibilities for creating most
synthesized sounds.
Some synthesizers offer more envelopes to be
assigned to different parameters, or even the
ability to "switch off" the surrounding amplifiers
and filters and to be assigned freely.
9. LFO (Low Filter Oscillator)
In a typical synth, the first parameter is an LFO
waveform which will modify the sound tone. The
second parameter is the Rate control, which
controls the speed at which the oscillator will
change the sound tone. Imagine a police siren with
a certain rate can make it sound faster or slower.
The amount parameter controls the intensity to be
applied to the modulation. In the example this
control would make the siren sound more serious
with tone higher tones.
