- The KontinuumLAB Instrument Kit keeps evolving.
I'm currently working on the 3rd version of the KLIK which, among other new features, will have wireless MIDI over Bluetooth, which easily connects to your phone or tablet. In this video I talk about what that means and show you how it works.
You can watch a step by step tutorial on how to get started with MIDI over Bluetooth using the ESP32 here: • How to make your own M...

Hi there! I am looking into designing my own instrument in the future, and your channel happened to be just a treasure of content on everything I would ever need: from woodwind mouthpieces to multi-capacitive touch sensors.
You mentioned in this video that you managed to create a board that supports up to 48 touch sensors, and that you will make a video on it in the future. Really looking forward to it, since I happen to need exactly 48 sensors on my instrument :)
Anyway, love your content, love your channel, thank you so much for sharing your DIY knowledge in an open and easy to understand format!
Really an Crazy engineer 🤝 appreciating your work✨
For those who may be unaware, there are relatively low cost USB to BT Midi adaptors like the Yamaha UD-BT01 which works great with very low latency on Android Windows and Apple devices... Just in case someone may be looking for a non DIY solution, I made my own EVI and this BT midi adapter works great.
The Yamaha UD-BT01 works great, as do other industry solutions, but they definitely can't beat the ESP32 on price.
This is a great development! A cheap solution for a highly portable DIY-instrument is a good direction to take. Looking forward to the future videos!
Thanks! More cool stuff to come ...
You are right... I decided to use the ESP-32 to add pitch bend and Midi messaging to my EVI using an accelerometer and tilt up/down/left/right. Could not find the Lolin here so I used the ESP-Wroom-32. Just finished the code and it works wonderfully on BLE, inclusive of low pass filtering on movements and tilt curves. Unfortunately I am not a programmer, but fortunately ChatGPT is!. A little debugging was needed but amazing what can be achieved with AI tools these days 🙂
Fluidsynth on Android is a very good solution as you can load your preferred .sf2 file and then simply connect the esp32 via BTLE and you are good to go...
Great content! KontinuumLAB you are cool
Thanks! Yes, someone mentioned Fluidsynth. I will have to check it out.
Great job! Can't wait for the next post.
Thanks Marco. I'm working on it 👍
Very interested in this. NEED IT.
Beautiful work! Im checking out your site!
this is so rad! can't wait to get it!
Thanks!
You are a genius!
the man is back!
Hi Pau! Yeah, it's been a while 😅
Been working on a new idea for an instrument, the chip you mention , the ESP32, will be looked into. What synth chip do you use to mate with the ESP32?
Is it possible to turn an eccomimi brain sensor into an EEG midi drone synth responds to your brain waves. Reason why I ask is cause I just picked up an eccomimi at the Goodwill fo $8
Can you make a saxophone midi out of a used sax?
Very professional presentation. Where can I get the code?
Thanks! There is still more development work to be done. The code will eventually be up on github.com/KontinuumLab
boa tarde, tennho um esp32 e gostaria de fazer um interface midi bluetooth pode me ajudar com squete e pinos de ligaçao diy.
Is the PCB open sourced anywhere?
Hi Darren. If you mean my adapter board, it's still not the final version. I'm using this iteration in my workshops at schools, and trying out different things with it. I'm still not totally sure what the final "KLIK3" version will look like, but I might share a version of it as open source at some point.
what battery is this? and what are the keys made of?
Way to go! Please explain more about ESP32 and BLE code and libraries used. I am working on a DIY BLE rhythm instrument which uses Bessel function to generate drum sounds
Thanks! I will try to make a more technical video, once I'm further along in development. Your project sounds very interesting 🎶
I put up a step by step tutorial here: ruclips.net/video/5peRGrayIJA/видео.html
Do you use a raspberry pi for onboard instruments?? And I am patiently waiting for this kit to drop! Can I get on a waiting list for it? I am also wondering if you go over arduino coding in the kits… thank you SO SO MUCH
Thank you! I use the Teensy microcontrollers for on board synths and audio. There is no waiting list for the KLIK3, but of course it will be announced here on the channel, so subscribers will be the first to know.
The kits come pre-programmed with a series of instruments, and don't include or require any Arduino lessons.
please do uno r3 midi tutorials
I don't really work much with the R3, and never for MIDI, sorry.
Hi ….does it wrk with iPad / iPhone device ? …. If not thn plz suggest which ble module works fine with iPhone/ ipad ? For MIDI over ble
Yes, it works fine with iphone and ipad.
@@KontinuumLAB hi I tried with normal Generic ESP32 board & it didn’t wrk for me …..Bcz lolin lite is not available …so my qtn is Wemos lolin 32 will work for this project or only lolin lite wrk best for ble midi…..?
Which can easily work with iPhone/ iPad devices as ble MIDI
@@Unbox-videos In theory all esp32 boards have BLE. You might be doing something wrong on the Arduino side. This tutorial is specifically for the lolin32 lite, so you might have to change something. I don't have info about other boards, sorry.
we need midi wireless USB.... is there any tutorial to make it with esp32?
yamaha , widi , cme is much expensive price...
Yeah, they are really expensive. I don't know of any good tutorials, I had to mess around with several BLE MIDI libraries in Arduino before I got it to work. Maybe I'll put together a quick tutorial myself...
@@KontinuumLAB it's to be great if there are new Innovation and tutorial from you man....
I put up a step by step tutorial here: ruclips.net/video/5peRGrayIJA/видео.html
where can I buy klik3 or download the code ???
The KLIK3 will eventually be available on www.kontinuumlab.com, but there is still more development work to be done. Once the project is finished, the code will be up on github.com/KontinuumLab
Would there be any way to have more than 48 sensors? I want to build a midi concertina with over 50 buttons. Also, have you tried any Android midi apps that allow you to download your own .sf2 files? E.g. Fluidsynth.
48 is the limit with the MPR121, because it only allows for 4 different i2c addresses. 12 sensors per board, so 48 sensors. You could expand further with multiplexers, like I've done when using the capacitive sensors on the Teensy boards... I haven't tried any apps like what you mention, but I'll check it out.
@@KontinuumLAB Is there only one I2C on the new board that you are using?
@@dtone1 That's an excellent point, thanks! The esp32 can actually handle 2 separate i2c buses, so I'll definitely keep that in mind when I design the final breakout board.
i love you,,,
