1
The Yamaha DX7
mixed analog oscillators with digital processing
sounded good but was a failure in the synth marketplace
had pairs of sine wars that used FM synthesis to create its sounds
2
In a sampler the Root Key
is always the lowest note in the instrument
is the first sample imported into or recorded by the instrument
plays a sample back at its original pitch
3
A sampler that uses keyswitching
can be locked onstage so others cannot play it
selects different sampled articulations of an instrument from different keys
can automatically transpose an instrument by playing in a different key
4
An Oscillator
generates short one-cycle samples
generates random noise
generates periodic waves
5
A Portamento control on an analog synth
sets the glide time between legato-played notes
allows the synth to be packed into a portable case
adds bandpass filtering to a raw oscillator tone
6
Additive synthesis
creates a complex sound from a chain of short one-cycle samples
builds up a complex wave from individually assembled sine wave harmonics
layers a collection of bright analog oscillator waves for a rich sound
7
A moduler synthesizer
tends to be smaller and more compact than a pre-wired synth
includes a set of pre-wired modules optimized for each synth's signature sound
requires patch cables (or the equivalent) to connect its various components (modules)
8
Patch cables
are required to connect the various modules in a modular synth
have a universal connector type that's used in all synths
are never used in modern modular synths
9
Modern sample libraries
often utilize hundreds of samples for greater realism
are smaller than ever, due to modern efficiencies
still utilize 8-bit resolution for efficiency
10
In FM synthesis a Carrier-Modulator pair
is a combined lowpass & highpass filter used to create richer tones
takes the place of a filter and amplifier EG
is a pair of (usually) sine wave oscillators that use FM to create rich tones
11
In a sampler Looping
can allow for infinite sustain of a note or rhythmic loop
allows for rapid repeat notes to be played on a single key
automatically converts a played melody to its retrograde
12
A Sampler
uses digital oscillators to create buzzy waveforms
is a mixtape with snippets of various songs
uses recordings of notes or sounds as its sound source
13
A sampler Keymap is
a collection of samples mapped across the keyboard
the range of transposition of a single sample
the collection of sampled instruments available in the sampler
14
Sequential Circuit's Prophet 5
was one of the first synths to have patch memories
used digital sound sources to create its sounds
included 5 stackable oscillators for a rich sound
15
In an analog synth Modulation sources include
Lowpass, Highpass & Bandpass filters
ADSR EGs, LFOs, & the keyboard itself
VCOs, VCFs, & VCAs
16
The stages of a typical 4-stage ADSR Envelope Generator are
Attack, Decay, Sustain, Release
Amplifier, Dropoff, Sustainer, Regulator
Activation, Dynamics, Saturation, Release
17
The first commercial pre-wired analog synth was
the ARP 2500
the Moog Modular
the Minimoog
18
The Oberheim SEM module
was designed to be used in multiples to allow for polyphony
brought digital technology to the Oberheim product line
was an effects processor with flanging, chorus & echo effects
19
The filter parameter that's most commonly voltage-controlled is
the Cutoff Frequency
the "Q"
the Slope
20
A multi-timbral instrument
can play multiple instruments at the same time
includes an EQ for multiple timbres for its single instrument
is polyphonic-that's what multi-timbral means
21
The earliest samplers
had a gritty sound due to their 8-bit resolution
were all virtual instruments
had only 24-bit resolution instead of the 48-bit resolution of modern samplers
22
A virtual instrument is
an instrument so expensive that most musicians can't afford it
a hardware instrument that mimics an acoustic instrument
a software plug-in instrument
23
Subtractive synthesis
uses a chain of one-cycle samples to create its complex sounds
filters & processes harmonically-rich raw waveforms
build up a complex wave from scratch by adding individual sine waves together
24
VCA stands for
Video-Cassette amplifier
Voltage-Controlled Amplifier
Voltage-Controlled Activator
25
In a sampler Velocity Zones
utilize multiple samples of the same note at different dynamic levels
utilize multiple samples of the same note on different keys
are very fast sequences of notes
