The Kontrol Freak is BACK, with a brand new video, and this one’s a monster. This video documents the creation of a brand new MIDI instrument, the “Virus Pad”. I go into a lot of detail, silly mistakes included, showing you how I make and connect everything, and how the code works, from start to finish.
The finished instrument has looper controls and two different playing modes, one for percussion and drums, and one for melody and chords. The project includes:
- DIY force sensitive resistors (FSR) out of velostat
- Multiplexers and voltage dividers
- Making an instrument box from recycled materials
- Sensor and MIDI code in Arduino, on a Teensy microcontroller
- Reading sensors and interpreting input
- many other interesting details.
The code for this project is here: github.com/Kon...
Here is a shorter video, where I show you how I developed the DIY FSR sensors: • Making a DIY analog fo...
The original Kontrol Freak videos are here: • Kontrol Freak
Hope you enjoy. Stay safe, and I'll see you in the Kontinuum!

I have zero experience creating electronics or coding, but I was able to get a start on a project I had long dreamed of creating thanks to this video. If I ever get it mass produced I will definitely sponsor your channel with some of my proceeds - keep doing what you are doing. I LOVE YOU LOL . Or I am just overwhelmed by gratitude lol - it's hard to tell right now. :)

I was learning the working principle of midi musical instruments, and then I found you, you are really a very good inventor, regardless of whether the product has a beautiful appearance, the important thing is that it works very well, and then you are still a very good Teacher, thank you for the video teaching

Wow this is so cool! You showed how there is no limit to throwing together a quick build and getting something going. The code is quite complicated, but I look forward to getting into your work and trying out some of the projects on your channel!

Hello, first of all, thanks for that great video. I'll definitely try to build a VirusPad on my own! I have a few questions about the parts you are using (sorry if these are stupid question, I'm an absolute newbie): - Is this a custom made breakout board or a bought one? If it's custom, are there any instructions I could find to make my own? - I'm a little overwhelmed with the multiplexer; is there any certain one you would recommend, or does it not matter? - My closest electronics retailer has only 8CH-Multiplexers, would it be possible to use two of those instead of one 16CH-Multiplexer? I haven't used microcontrollers in a long time, and when I did, they were pre-built and I was "just doing the software part", without much understanding of the hardware (it was in a programming class about C), so, sorry again if these questions are stupid. I'd really, really appreciate an answer and hopefully I can start soon building my own!

The breakout board is an early iteration of my KLIK (KontinuumLAB Instrument Kit) breakout. You really don't need it for this specific build, it just provides a practical place to plug in the sensors and multiplexer module. Great for beginners. The multiplexer pin numbers are in the code, control pins are: 12, 11, 10, 9 - and the sensor pin is 15. I use the 74hc4067 multiplexer. Cheap modules are available online. You could use 2x 8 channel ones, but that would mean changing the circuit and code a lot, and I don't recommend it. Hope that helps. Happy making!

Los sensores Funcionan como un piezo electrónico?

No. Un piezo genera electricidad cuando se deforma. Estos sensores reducen su resistencia cuando las presionas.

Pleas . I have 1 question. What is the black plastic or material?
@KontinuumLAB
@KontinuumLAB Жыл бұрын
The type of material is called velostat. I get it from protective "electrostatic" bags for components. I talk more about in this video: kzfaq.info/get/bejne/nalylayWrprchHk.html
