3. ✦ Robert Moog released the first commercially available modern synthesizer in 1965.[citation needed] ✦ In the late 1960s to 1970s, the development of miniaturized solid-state components allowed synthesizers to become self-contained, portable instruments, as proposed by Harald Bode in 1961. ✦ Along with the development of Musical Instrument Digital Interface (MIDI), made it easier to integrate and synchronize synthesizers and other electronic instruments for use in musical composition. ✦ In the 1990s, synthesizer emulations began to appear in computer software, known as software synthesizers. Later, VST and other plugins were able to emulate classic hardware synthesizers to a moderate degree. Monday, 17 December, 12

7. Electronic oscillators – create raw sounds with a timbre that depends upon the waveform generated. Voltage-controlled oscillators (VCOs) and digital oscillators may be used. ▪ Voltage-controlled filter (VCF) – "shape" the sound generated by the oscillators in the frequency domain, often under the control of an envelope or LFO. ▪ Voltage-controlled amplifier (VCA) – After the signal generated by one (or a mix of more Voltage- controlled oscillators), modified by filters and LFOs, and the signal's waveform is shaped (contoured) by an ADSR Envelope Generator, it then passes on to one or more voltage-controlled amplifiers (VCA) where. ▪ ADSR envelopes - provide envelope modulation to "shape" the volume or harmonic content of the produced note in the time domain with the principle parameters being attack, decay, sustain and release. These are used in most forms of synthesis. ADSR control is provided by Envelope Generators. ▪ Low frequency oscillator (LFO) – an oscillator of adjustable frequency that can be used to modulate the sound rhythmically, for example to create tremolo or vibrato or to control a filter's operating frequency. LFOs are used in most forms of synthesis. Monday, 17 December, 12
