LO2: Be able to use the editing functions of a synthesiser
What are the editing functions of a synthesiser?
A synthesiser can create unique sounds; however the user must know all the ins and outs of the synthesiser in use. Most, if not all, synthesisers should have the following functions. These functions are used to in unison to create a unique sound.
Oscillator: An oscillator is a device that generates an oscillating wave (often a sine or square wave), giving a wavelength, amplitude and a frequency.
Amplifier: Is used to control the level of signal over time
Filter: Is the part of the synthesiser in which you can shape its tone and give the sound its unique character.
Envelope generator: ADSR Attack, Decay, Sustain and Release helps a user to further manipulate the sound by changing a sounds ADSR.
LFO: Low frequency oscillator is a function that helps you use the frequencies you cannot hear with the human ear and then use it to modulate audible waves such as square, triangle and saw.
Modulation: Frequencies can be modulated; modulating a frequency using a simple wave (sine, saw etc...) can even create complex wave forms for further character.
Patch-bay: Sending signals from one place to another using bays. This is normally done by using jacks or XLR leads.
I used the oscillator to increase/decrease generated waves (frequency) in my synthesised patch. Different wave forms create different sounds and the oscillator along with the ADSR helped me change my synthesised patch. ADSR helped me to make noticeable changes to the sound. Attack, Sustain Release and Decay was used in all my sounds to create different effects.
I used the LFO (low frequency oscillator) to manipulate the lower frequencies that cannot be heard with the human ear. I normally use an LFO in order to use the lower frequencies and use them fill in the emptiness of a sound in the background.
At first I wanted to create a basic EDM song, however during the process of making my patches. I created the 'retro game' patch and decided to challenge myself to try and create a new EDM sound with this new patch. This patch consisted of square waves which gives it a punchy sound. Then by changing octaves from '8 to '4 divides the octave length by 2 (middle c on '8 = middle c on piano = 440Hz). Changing the value to '4 gives it a dark 'gloomy' sound. Then having the filter cut off on 5 allows the higher frequencies to pass whilst cutting off the lower frequencies; which is how the retro sound was first brought about. My intention was to have a sound which had a fast short attack with a bit of sustain so the sound wouldn't ring out when I hit another note. The last thing I did was to add a bit of glide so that notes don't overlap each other when played after one another.

Presets: Presets are settings of a synthesiser saved for a certain sound. Presets come built in with logic synthesisers but can also be made and saved by the user; presets can also be made by the user.
Monophonic: A monophonic synthesiser is a synth that produces one note at a time. Monophonic generally means to have a melody without having harmonies played.
Polyphonic: Meaning to have multiple notes played at once including harmonies; polyphonic synth produces multiple notes at once.
Parameter select: Is anything on a synthesiser you can change by a nob such as glide, drive, ADSR etc...
