Roland TR808

An iconic machine

One amazing audio electronic device that has been brought up many times in the music industry, has to be mentioned on one of my blogs. It’s iconic for its memorable drums sounds such as the 808 kick, 808 snare, hi hat and many more. The Roland TR808 is the origin for the “808s” and it became popularized through many hit songs in hip-hop. In this blog I will go through the history of this machine and its impact on music and audio electronics.

History

https://www.midi.org/midi-articles/ikutaro-kakehashi-passes-away-at-87 Ikutaro Kakehashi. Legendary Japanese Engineer.

Funnily enough you would think that my praise in the introduction would mean that it somewhat was commercially a success. However that is not the case. Quite the opposite. But let’s rewind time a bit to its invention. It was created by Ikutaro Kakehashi in 1980. He was born in Osaka and got his start through repairing broken watches and clocks later going on to graduate and earn a degree in mechanical engineering. He founded Roland Corporation in 1972 and began creating synthesisers and drum machines. What separated his iconic TR808 sound was the drum machine did not replicate accurate drum set sounds, it did more of a futuristic drum sound. Most memorable was the bass heavy sound.

Impact on music

The Roland TR808’s impact on music has been phenomenal to say the least. Although it failed commercial and it’s product line discontinued, its drum sounds were in many top hip hop hits. It spawned many great artists and a new type of artist coined with the nickname “bedroom producers”. Nowadays bedroom producers are quite the common way of how people get interested into music such as myself. One great artist is Rick Rubin who used one in his NYU dorm. The first hit to be associated with the TR808 was Planet Rock by Afrika Bambaataa in 1982. Then it was Marvin Gaye’s Sexual healing that brought it up to mainstream success. Famous tracks include it’s Tricky by Run DMC, Rock the Bells by LL Cool J, Emergency Room by Rihanna and Kanye even created an album called 808s and Heartbreaks. Many of these famous hits are in the genre of hip hop however nowadays this drum machine is being used in genres other than hip hop such as EDM. In my experience listening I started to notice that after doing some research and it is quite interesting to see how an audio electronic can have such a massive impact on the music industry.

Audio electronic impact

Many of Roland’s competitors have tried to recreate this product such as Behringer’s RD 808. It doesn’t even try to hide the fact that it’s trying to make an exact clone. HINT HINT, the names are very similar. The 8raw8 analog drum expander is quite an interesting “clone”. I recommend taking a look at it. Here is the link. https://youtu.be/sFrJDUWA6Gk . I don’t necessarily dislike these “clones”, in fact I welcome innovation as it always leads to beautiful spurs of spontaneous art.

A great machine.

Wow! This research on the TR808 has been quite fun. It’s quite amazing how technology can impact. Maybe one day I could be like Ikutaro Kakehashi ¯\_(ツ)_/¯. If you enjoyed reading this blog I recommend watching the documentary 808 available on Amazon Prime. That being said I was surprised to see how much I enjoyed this research so I am looking forward to researching another famous piece of hardware in audio electronics. The Neve 8028 mixing desk!!!. See you on the next blog post :D.

Audio circuits!

Surfing the internet many interesting things come up such as the Top 10 video games of the year or cute and funny cat videos. However that not what has caught my attention this past week. Funnily enough it has been the topic of audio electronics. Audio circuits to be more precise. I browsed the internet on audio circuits and I came across a few interesting websites that detailed a lot about how to build simple circuits with Arduino. In the following blog post I will detail some simple Arduino board circuits to help me understand audio electronics much better and hey!, if you find anything interesting feel free to try them yourself.

RGB LED

RGB has been getting ever so popular with gaming products on the rise in terms of sales and production. I’ve always wondered how they work and I finally found the circuit that showed just that.
To begin the parts needed are:

  • (1) Arduino Uno
  • (1) USB A-to-B cable
  • (1) Breadboard
  • (1)RGB LED
  • (3 )300 ohm Resistor
  • (5) jumper wires

RGB LED circuit

Steps:
Connect the Arduino board to a computer using a USB cable. Download the file Circuit_09_RGBLED and open the project code in Arduino.
Select the board and serial port so that the code is able to run through the board. Ensure everything is running and once that is done, click the upload button to send the sketch to Arduino.
What should follow is that the LED will turn on and change different colours.

Push Button

Learning how to create a circuit with a push button is important if you want to learn to create anything as a majority of products have buttons with functions on it. This specific circuit that I am going to show has an LED light switch on after a press of a button. For me, learning how this circuit works is beneficial as it opens up the idea of adding buttons to my. project. These are the parts you are going to need:

  • Arduino uno
  • USB A to B cable
  • Breadboard – half size
  • 1 LED 5mm
  • 220 Ohm resistor
  • 10k ohm resistor
  • push button switch
  • 6 jumper wires

Connect the Arduino board to a computer using a USB cable. Download the file and code related to this project on Arduino.com and open the project code in Arduino.
Select the board and serial port so that the code is able to run through the board. Ensure everything is running and once that is done, click the upload button to send the sketch to Arduino.
What should follow is that the LED will turn on after a press of a button.

Much More

I could spend more time detailing more circuits on how to make them however I’ll just leave it at these 2. When you learn 1 circuit it is possible to combine these circuits to complete ‘harder’ functions. For example a circuit with a button should look similar regardless if the function is to turn on a button that makes a noise or emits a light. Overall the world of electronics is daunting at first however if you take it step by step and circuit by circuit it all comes together.
