Introduction

                                Our objective here is to build a synthesiser with vast sound design potential and importantly need to be simple and user friendly so this it our main principal objective. Therefore, we will build the instrument without a complex envelope, LFO or filter and so on but will functioning just like any other synthesiser. Base on our research, there are numbers of synthesis techniques developed that are often different from each other such as Wavetable, Additive and subtractive synthesis etc. In our case, we have decided to build a subtractive synthesis. Because it is commonly viewed as the classic synthesis technique also has the longest history.

In order to achieve our objective, we are aware that we need to plan well and also undertaking lots of research on Oscillator, Filter, Envelope, LFO all the components that we need to understand. Understanding how they modulate and shape the sound is very important for building the synthesiser and also the type of synthesiser features we are going to use. Most subtractive synthesiser will consist of many more options and variation but in our case we have decided to start with the standard theme and then gradually build upon on that and at the end of this project we will achieve a simple subtractive synthesiser with vast sound design potential also with some effects and step sequencer on it. At the moment, we have just started with our prototype with the standard features things like VCO, VCO and Pitch control, VCA – Amplitude control, VCF – Filter and Filter control, LFO and Envelope etc.
