How to make your own MIDI over Bluetooth instruments 

That cardboard guitar thingy is the prettiest thing I've seen in a good while 😍

I want to ask? what about the bluetooth latency

I totally love this. We had just start teaching our kids programming, and this will be a super fun project to introduce them to arduino. Thank you for showing how easy it is to get started!

Well done! Such a good, no nonsense tutorial. This could also serve as a great introduction for anyone who's never used the Arduino environment before, because you leave no steps out, you show how easy it is to get Arduino set up and then get pretty amazing results so quickly with such few lines of code. You rock. Keep up the good work!!

Funny how you pressed the button harder to get more velocity, while there is really no need for that. It's like leaning in curves when playing a racing game ;) Good tutorial, opens op a lot of inspiration!

Hello! I have an idea for a project that I think should be pretty simple but I haven’t found any good examples of it online yet. I’d like to build an artificial sound machine for small electric vehicles so that drivers/ pedestrians can hear you coming. It should be easy enough to use the 0v-4v signal from a standard hall throttle to modulate the sound along with the speed right?? I believe lots of people will have interest in a device like this, especially because many countries will soon be enacting new laws that require small electric vehicles to play sounds for safety. I am about to order a teensy microcontroller and hopefully I will be able to figure this out. When I had the idea I immediately thought of you because I imagine this would be a simple project for you. If I have any questions while working on this I might ask you if you don’t mind…. Or if you wanted to I think it would make a great subject for a video, and would likely bring many other viewers to your channel.. just a thought.😄

Thank you to make it easy to us ! At least.. it look easy ;-)

This is excellent content.

This is Gold!

Awesome content as always! I made a custom "flute" with a Feather 32u4 Bluefruit, which works both through USB and MIDI-BLE. I still have a WIP version 2 with a Teensy (for working standalone) and a Adafruit BLE SPI Friend, but haven't finished it yet. It will have an air sensor based on your videos about wind instruments, thanks A LOT for that, it never occurred to me that approach! I guess my v3 is going to be based on ESP32! Greetings from Argentina :D PS: if I go to Barcelona next year I'll send you a message to see if you have a workshop running or something like that

Thanks for a great tutorial, it's been very helpful with my project. I'm wondering if it's possible to connect to my Macbook using BLE? For some reason the device never shows as an option in the bluetooth settings.... EDIT: to anyone trying to figure this out in the future, I had to connect via the Audio MIDI settings on my MacBook. There's an option for Bluetooth in there, connecting via the "normal" Bluetooth settings wouldn't work for me. Thanks again for a great tutorial!

I’m appalled at the level of views these videos have. I know I have to be one out of a billion people that want to learn this stuff!

Hello, wonderful project. I did all the steps exactly as you did In the video but I'm am getting error with the code. Can you help with this? Also the kit on your website is sold out, can you tell us when it will be available?

Is there any noticeable latency when using bluetooth that would interfere with using this for percussive instruments?

Thanks but this is a midi _controller_ . The _instrument_ here is the phone. Do you have anything on creating an esp32 midi instrument?

To improve the experience you may consider increasing size of code sections..I couldn't read the code

Amazing ,thanks

Thank you for the video! - I have a question: the first time I used the device it worked fine, but after the first time, the controller stopped working and the MIDI BLE App as well as the Synth app can't see it. Oddly, the Android phone normal BLE keeps seeing it and contacts with it, did you ever experienced something like this??

Sir make a video in which mobile can connect drum machine to wireless midi and play it.

I can’t figure out how many analogio’s this has… is it only one? And do you have any recommendations on a multiplexer?? Thank you so much. Can’t wait to get your kits!

Thanks for this lesson/tutorial I was able to make it work with android like in the video, but I don't know how to make it work in the linux =/ Do you have any idea?

Inspiring video and I have a breadboard MIDI controller working using your tutorial and a LOLIN D32, however ... BLE MIDI Connect is not compatible with Android 13 😢 I have written to the developer to ask if they plan to make it so, but in the meantime do you know of any other BLE MIDI connection utilities that might work on Android 13?

thank you

So, is there a version of this with Classic Bluetooth instead of BLE? Thank you!

Have you had any luck doing this with Windows? I've found it just auto disconnects the device after pairing when using the ESP32-BLE-MIDI library.

Hi everybody. Your work is good and deep. I have few question to ask. I try to control ableton from Android with midi commander app. I tried to make a midi ble bridge to USB midi with a esp32-C3.. But it doesnt work. I receive midi message from Android app to esp32. But i can't go further. I tried with hairless midi serial bridge, but nothing incoming. Any ideas ? Thx.

Bluetooth Latency? Why did they go with BT Instead of WiFi?

I'm trying to use this with Macbooks, and even though it compiles and uploads, none of my Macbooks recognize it in bluetooth. I have three different Macbooks (2014 Intel, 2022 M1, and 2023 M2), and none of them see it. I have tried completely uninstalling the IDE, and reinstalling, and even installed the old version (1.8.3) with no success. Of note is that SerialBT works fine on any of the three boards I have tried (Wemos Lolin 32 Lite, ESP32WROOM32, and ESP32WROOM32U), but no luck on any of them with the LE-MIDI. Any ideas?

One question 🙋‍♂️,while using it on windows it have direct midi connection or does it need an external program like hairless midi?

❤Hi can I use Lolin 32 V1.0.0 Instead of Lolin 32 lite ? Plzzzz Reply ASAP ❤

Can we use this esp32 board to control a bluetooth speaker

There is a way to use rotary encoders with esp 32 as ble midi controller?

I'm making my Midi flute using ESP + Midi BLE, but have some delay with FL Studio. My loop delay is only 10ms, but I'm feeling more using the software. Some have a suggestion?

Can you use just the wire (due to latency?)

Hello sir, i want to know about how to mpr121 capacitive sensor connect button or arcade button is it possible or plz help me about this and how to note assign a specific note or midi note

these can even work with Arduino nano with hc-05 bluetooth module?

Thanks, cool video. But I was actually looking for a way to use an ESP32 as an alternative to a BLE MIDI adapter like Yamaha UD-BT01. Seems like this is part of the way there, but I have no idea how to do the next step. I wnt to hook this up to USB cable output of a controller to get midi from a controller into the ESP32, so the ESP32 can relay it via Bluetooth to a computer/synth. Any clues on how this can be done, or where I should look for more info online?

Would this work on a ESP8266 Board? This is what I have

i have a arduino nano board. can i ad an esp32 breakout board to make it the same as yours?

Muchas gracias por favor no pares! Aunque tuve un problema al intentar utilizar la librería (supongo que se actualizo), dejo por acá la solución por si a alguien le ocurriera lo mismo. Sustituir la declaración de la librería por lo siguiente: #include #include #include #include #include #include Seguro a alguien le ayuda! un abrazo!

THIS ISNT WORKING FOR ME, SUGGESTS nIMBLE BUT THEN I GET LOST IN CODING. ANY SUGGESTIONS?

When I open SynprezFM and scan BT devices, it prompts "AWESOME_INSTRUMENT connected" but inmediatelly it prompts "AWESOME_INSTRUMENT disconnected". I've tried multiple libraries, different apps, and nothing works. What can I do? Thanks!
