A Beginner's Guide To Synthesizers and Synths - Music

By Melvin Spencer

The primary sound that you hear in the patches is created by the oscillators, and is then fed through the synthesizers signal path. If you set oscillation to a genuinely low pitch, you'll end up with gaps because the waveform is continuously dependant on the speed pitch of the note. And so the different sounds are created by the shape of the waveform, which is the product of oscillation.

Here're the average wave form. For a sharp biting type sound, you require the saw-wave. It's named as this because it's shape is identical to those on a saw blade

To get a soft mild tone then you would want the Sine Wave, which is shaped like a horizontal S; it has a smooth up and down shape to it.

A unique color of noise will produce noise although its not actually a wave form

To get that sound that simulates a hollow reed you require the square wave. This is distinguishable by its almost perfect square outlook.

A variance to the square-wave is the pulse wave, even though it's just half as wide. It has the engrossing ability to have a modulated width. Maybe youve heard this as being related to as the Pulse Width Modulation.

To find a glad medium between the saw and sine wave you would require the triangle wave, which's the shape of a triangle.

Most frequently a synthesiser has two to three oscillators. Being as that's the case, you could do numerous entertaining stuff by combining the wave forms as one. And you could tune them so theyre different from each other. It can be tuned in semi-tones, octaves or in cents. A swirling untuned sound is created by many oscillators which are cents apart from each other. Cents is a 100th of a semi-tone.

There is an oscillator known as a low frequency oscillator. Its frequencies are undetectable provided you physically tune it into a regular hearing range. It's job is to modulate the pitch of the oscillator or the filter frequency. The start stop of the waveform is quite evident because the LFOs are like the oscillators in that they still use general wave forms. When utilised the right way for instance the sine-wave allows you to hear an increasing or decreasing sound of the wave shape. Animation and moving texture would be the end result for your synthesiser sound if done properly. - 23802
