PCM Synthesis

 

Although not bringing anything truly new to the synthesis party, a number of instruments took advantage of sampling technology and replaced the standard
OscillatorIn analogue circuitry an oscillator is an AC generator whose output voltage is used to produce a signal of variable frequency usually from 20Hz up to 15kHz. The raw oscillator sound usually has one of a number of basic waveform shapes or timbres (sine, square or sawtooth) and is used as the basic sound source for many analogue synthesizers.

PCMPulse-Code Modulation: a method of encoding used in most digital recording, including CD audio, in which an analogue signal is sampled thousands of times per second and the amplitude of each sample is stored as a discrete binary number.
PCM
Sample1) In digital audio, a sample is numerical representation of amplitude at a single point in time. Thousands of samples are taken every second, corresponding to the sample rate, and stored as binary numbers. The analogue waveform is recreated by passing the samples back through a digital-to-analogue (D/A) converter. 2) A digital recording of an instrument sound, percussive hit, loop or sound effect, used in music production.

, the range of them made it popular with gigging musicians, who for the first time were able to call up a fairly realistic palette of sounds. Both Roland’s D50 and Korg’s M1 were very popular, continuing the demise of the analogue subtractive synth with its more limited range of sound, and heralding the beginnings of the workstation instrument.
