Music Making and Production - Synths and Sound Synthesis
The original sound that you hear in the patches is made by the oscillators, and is then fed through the synthesiser signal path. Say you set oscillation to a genuinely low pitch, you would end up with gaps because the waveform is unceasingly dependant on the speed pitch of the note. Therefore the different sounds are created by the shape of the wave form, which is the product of oscillation.
Here’re the average wave form. For a sharp biting type sound, you need the saw-wave. It is also known as this because its shape is similar to those on a saw blade
To obtain 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 would produce noise although its not genuinely a wave-form
To get that sound that simulates a hollow reed you require the square wave. This is distinguishable by it’s near perfect square outlook.
A variance to the square wave is the pulse wave, even though its just half as wide. It has the amusing ability to have a modulated width. Perhaps you have heard this as being related to as the Pulse Width Modulation.
To find a glad medium between the saw wave 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 is the case, you can do some fascinating stuff by combining the wave forms as one. Plus you can tune them so they are different from each other. It could be tuned in semi-tones, octaves or in cents. A swirling untuned sound is produced by many oscillators which are cents apart from each other. Cents is a hundredth of a semi-tone.
There is an oscillator recognized as a low frequency oscillator. Its frequencies are undetectable unless you physically tune it into a average hearing range. Its job is to tone the pitch of the oscillator or the filter frequency. The start and stop of the wave form is quite evident because the LFOs are like the oscillators in that they all the same use regular wave forms. When utilised properly for example the sine-wave permits 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 complete decently.
