Synthesis - Part 7

So, welcome back to another instalment in the ‘ongoing, hell, when’s it ever gonna end?’ synthesis tutorials.

In this tutorial I want to cover a few quite important parts of analogue synthesis, notably: sample and hold, sync, cross modulation, keyboard tracking, and velocity.

Sample and Hold S/H or S & H

Phase and Harmonics

This month I am going to concentrate on a few crucial areas of synthesis, with a general overview of what has been covered. However, to fully understand what I am talking about, you need to understand, yep, the original concept of sound, but in this instance, with emphasis on harmonics.

First, let me glide over the concept of phase. Whereas I promised we would cover this topic in more detail in reference to filters, I am now forced to bring it up in reference to the overall concept of wave shaping.

FILTERS 2

In the last tutorial I mentioned the term resonance.

So, let us start this tutorial with resonance.

Resonance

Q - Also known as ‘width of the filter response’, this is the ‘centre frequency’ of the bandwidth and is measured in Hz. Also know as bandwidth and resonance.

Synthesis - Part 3

There are many different types of synthesis and with varying names and sometimes their names can get very confusing as, quite often, writers like to use their own titles for a type of synthesis that is already well known. So, I am going to describe the most important and most commonly used types of synthesis and I will use their most common names as opposed to some of the fancy names that other writers like to adopt.

BUT, before we get deep into synthesis you need to learn one of the most important aspects of sound….HARMONICS

Synthesis - Part 2

In this tutorials we are going to deal with what is probably the most important aspect of shaping any given sound, the ADSR, and I believe you now want to know what that means? But before we get onto this crucial topic we need to understand another component of sound and that is Volume or Loudness and how it is measured. We discussed Amplitude in Part1 but I deliberately left out the measurement scale dB, so that we could apply it later when we come to cover synthesis in more detail. For now, here is a simple explanation.

Synthesis - Part 1

Understanding Sound

To understand any part of synthesis you need to understand sound, what it is, how it moves, how we perceive it and why we perceive it the way we do. Once you understand this then shaping it or manipulating it becomes so much easier.
