Well done! Great page and really fast delivery on my son's xmas drums. He's sure to love them. This is why we're ordering again

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.

of waveforms held in memory that can be strung together in any order you like, and then played in sequence as the basis of a sound. The result of this technology is that the instrument has a much broader palette and more dynamic timbral sound than that offered by the typical sawtooth, pulse and sine waves of analogue synthesizers, which relied on a

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.
