The basic 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 really low pitch, you will end up with gaps because the wave form is unceasingly dependent on the speed pitch of the note. So the different sounds are produced by the shape of the waveform, which is the product of oscillation.
Here’re the standard wave form. For a sharp biting type sound, you need the saw wave. Its named as this because its shape is identical to those on a saw blade
To get a soft mild tone then you will want the Sine-wave, which’s 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 really a waveform
To get that sound that simulates a hollow reed you need the square wave. This is distinguishable by its nearly perfect square appearance.
A variance to the square wave is the pulse-wave, although its merely half as wide. It has the interesting ability to have a modulated width. Perhaps you’ve heard this as being related to as the Pulse Width Modulation.
To find a happy medium between the saw wave and sine-wave you will need the triangle wave, which peculiarly enough is shaped like a triangle.
Most frequently a synthesizer has two to three oscillators. Being as that is the case, you can do various amusing stuff by mixing the wave forms together. Plus you could tune them so they are different from one another. It can be tuned in semi-tones, octaves or in cents. A swirling untuned sound is created by many oscillators which’re cents apart from one another. Cents is a hundredth of a semitone.
There’s an oscillator known 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 stop of the waveform is rather evident because the LFOs are like the oscillators in that they all the same use basic waveforms. When applied decently for instance the sine wave permits you to hear an increasing or decreasing sound of the wave shape. Animation and moving texture will be the end result for your synthesiser sound if complete decently.
