Unit 5: Synthesizers

The Telharmonium was an early electrical organ, Developed by Thaddeus Cahill in 1896 and patented in 1897. The electrical signal from the Telharmonium was transmitted through wires and it was heard on the receiving end by means of "horn" speakers. Like the later Hammond organ, the Telharmonium used Tone wheels to generate musical sounds as electrical signals by additive synthesis. It is considered to be the first electromechanical musical instruments.

the Telharmonium was unsuccessful for a number of reasons; One being its size and complexity, the machine weighed several tons and could not be moved or transported with ease. The instrument required a lot of Electrical power to operate and the sounds it produced were very limited as it lacked a lot of the features the later Synthesizers would have.

The theremin is an usual instrument mainly because it is played without actually touching it. It was invented by Leon Theremin in the Soviet Union 1920s. The Theremin involve the manipulation of electromagnetic fields around two antennae that make the instrument look rather like a weird lectern. Players control sounds by moving their hands and fingers around a vertical antennae to raise or lower the tone, and up and down over a looped antennae to control volume.

The theremin is a very niche instrument because it rarely appeals to musicians and only a small margin of musicians will want to use the theremin for their respective genre of music
the following video shows the theremin being used by inspired by "Carolina Eyck" covering the song "Ecstacy of gold" by Ennio Morricone which was used in the film "The good. the bad and, the ugly". also this track is heavily used by Metallica before their concerts.

Subtractive Synthesis

Subtractive Synthesis is a method of sound in which overtones of an audio signal are attenuated by a filter to alter the timbre of sound.

Additive Synthesis
Additive Synthesis is a sound synthesis technique that creates timbre by adding sine wave together.

FM Synthesis
Frequency Modulation Synthesis is a form of sound Synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. The frequency of an oscillator is altered in accordance with the amplitude of a modulating signal.

Analog Modeling Synthesis
An Analog Modeling Synthesizer is a synthesizer that generates the sounds of traditional analog synthesizers using digital signal processing components and software algorithms. Analog modeling synthesizers simulate the behaviour of the original electronic circuitry in order to digitally replicate their tone.
Granular Synthesis
Granular Synthesis is based on the same principle as sampling. It is a sound synthesis method that operates on the microsound time scale.


Alchemy is an easy-to-use, yet powerful sample manipulation synthesizer. It offers numerous real-time
performance controls and an extensive preset library. Alchemy features additive, spectral, and granular synthesis and resynthesis, sampling, and virtual analog engines. An Alchemy preset can contain up to four sources, each using one or more synthesis engines. You can morph or crossfade between these sources. Dozens of modeled analog and digital filters are available, in addition to multiple racks of integrated effect units and an extensive modulation section. Alchemy also features a powerful arpeggiator that can control each source independently and provides flexible pattern modulation options.

UNIT 8: Research

Image
Throughout the course of this project I have done a lot of research in this project so today I will show and explain all the research I've done in this project. What you see here the tabs for "Enter Sandman" and "Lucretia". During the creation of my First and original song "Take it to your grave" I wanted to figure out a new section for my song as I didnt know what would come next. I didn't exactly use this as after i finished the solo the song goes into an interlude so i did not use this but it is good for the future in songwriting.  i knew what i wanted to do with my song, it involved getting a sample from a show called "Invincible" where a character named "Conquest" tells the main character all about his struggles and his loneliness before attempting to kill him followed by him saying "Take it to your grave" which inspired the name of my track. In order to extract Conquest's voice, I had to download the youtube ...

L3 Unit 5 & 6

This will be my on going diary for units 5 and 6 dedicated to the creation, recording, and mixing of my music video.   For this assignment, I need to write a song, record it in logic, mix it, record a music video, edit the music video, and release it on YouTube. The song that my band have chosen to recording a music video for is "Take it to your Grave" which is a song about the character named "Conquest" from the comic book TV adaptation "Invincible". In the season 3 finale, Invincible faces planet Viltrums most feared warrior "Conquest" who batters invincible from pillar to post. During the fight, Conquest opens up to our hero and discusses his feelings of loneliness and isolation from his own race and how he doesn't even get his own name, only a purpose. He tells Invincible "Take it to your Grave" and tries to kill him. I thought Conquest would make a fantastic theme for a song so I wrote Take it to your grave about him I wrote th...

Unit 8: Week 1

 So far i have learned how to put a guitar into logic using an interface and how to record my guitar parts into logic. I choose to play a harmony from the 1986 track by metallica "Master of Puppets". i chose this because it is a very good solo and it will get me into harmonizing which i had never done before  First of all, i had put the interface in control of the sound by changing the output and input to the interface. I then changed the input and output in logic to the interface. I then plugged a guitar cable into the interface but there was no sound on it so i had to change the interface to channel 2 so the system could hear my guitar. I checked a tab for master of puppets and changed the tempo to 106 which orchestrates the speed of the song. I had then started recording the two guitar tracks which harmonized with each other and after hundreds and hundreds of takes, i finally got the perfect harmony. I am proud of what i created in logic since this was my first time using...
