1
To create a percussive envelope with an ADSR envelope generator
Sustain would be set to zero
Attack would be set to its slowest value
Decay & Release would be set to their fastest values
2
An analog synthesizer
uses oscillators and filters to shape its sounds
uses a chain of one-cycle samples to create its complex sounds
uses samples recorded on analog tape as its sound sources
3
VCA stands for
Voltage-Controlled Activator
Voltage-Controlled Amplifier
Video-Cassette amplifier
4
The earliest samplers
were all virtual instruments
had a gritty sound due to their 8-bit resolution
had only 24-bit resolution instead of the 48-bit resolution of modern samplers
5
Pusle Width Modulation (PWM)
is only available on digital emulations of analog synths
allows for dynamically changing the shape of a pulse wave via LFOs or EGs for timbral variations
is only possible on modular synths
6
In a modeling instrument Exciters & Disturbers
emulate vibrating objects and the physical devices used to trigger notes on them
can only be used to create strange & unusual sounds
are used to modulate the modeler's traditional oscillators & filters
7
In a sampler the Root Key
is always the lowest note in the instrument
plays a sample back at its original pitch
is the first sample imported into or recorded by the instrument
8
The two main parameters of an LFO are
rate & depth (intensity)
cutoff & resonance
attack & decay
9
White & Pink noise
are filters that can be used to add color to various sound sources
are digital processes that are available in modern synthesizers
are random signals that can be used as sound sources or modulators
10
In a sampler Velocity Zones
are very fast sequences of notes
utilize multiple samples of the same note on different keys
utilize multiple samples of the same note at different dynamic levels
11
Sequential Circuit's Prophet 5
included 5 stackable oscillators for a rich sound
was one of the first synths to have patch memories
used digital sound sources to create its sounds
12
The Yamaha DX7
sounded good but was a failure in the synth marketplace
mixed analog oscillators with digital processing
had pairs of sine wars that used FM synthesis to create its sounds
13
Patch cables
are never used in modern modular synths
are required to connect the various modules in a modular synth
have a universal connector type that's used in all synths
14
Buchla synthesizers
are virtual clones of traditional Moog synthesizers
are modular designs that lean toward more experimental sounds
were first introduced in the 1990's
15
The filter parameter that's most commonly voltage-controlled is
the Slope
the Cutoff Frequency
the "Q"
16
An analog synth's voltage-controlled modules include
VCO, VCF, VCA
VCX, VCY VCZ
VBR, VCR, VDR
17
Multi-sampling
uses many samples from the same source to minimize sample transposition
means that the sampler is polyphonic
means that the sampler has many different sampled instruments to choose from
18
Synthesizer parameters
are the adjustable controls used to shape sounds
are the dimensions of the synthesizer's case
are all always preset to their optimal settings to ensure the best sounds
19
The stages of a typical 4-stage ADSR Envelope Generator are
Amplifier, Dropoff, Sustainer, Regulator
Activation, Dynamics, Saturation, Release
Attack, Decay, Sustain, Release
20
A Sampler
uses digital oscillators to create buzzy waveforms
uses recordings of notes or sounds as its sound source
is a mixtape with snippets of various songs
21
A virtual synthesizer is
a hardware synth that includes both analog & digital technology
a software synth, often a plug-in emulation of an analog synthesizer
a hardware instrument that sounds like a synthesizer but is really a sampler
22
Modern sample libraries
still utilize 8-bit resolution for efficiency
are smaller than ever, due to modern efficiencies
often utilize hundreds of samples for greater realism
23
In an analog synth Modulation sources include
Lowpass, Highpass & Bandpass filters
ADSR EGs, LFOs, & the keyboard itself
VCOs, VCFs, & VCAs
24
The East Coast & West Coast schools of synthesis
generally follow the design philosophies of Moog vs Buchla, respectively
tend to use all-digital vs all-analog technologies, respectively
both incorporate all-digital technologies
25
In a sampler Transposition
automatically matches each sampled instrument to the key of a particular song
morphs between two different instruments loaded simultaneously
is automatically done to all samples within a user-specified range
