which baterry are you using? cause i´ve been trying with several and the don´t make the bluetooth work, it just conects to my computer but don´t send midi.
I need a sketch that will let me connect the ESP32 to my windows 10 pc via usb, and, act as a BLE Midi instrument to send notes, etc to my Ipad... as RTPMidi is giving me problems, bieing out of sync, slow, and missing notes 😕 wish they has some BLE midi USB dongle for pc... that would do that, but I bet they are crazy expensive, I wanna DIY
A beautiful solution! I just wonder if you also experience the same jitter when using the test sketch? The playback is very irregular when connecting the ESP32 to my Mac via the Bluetooth Midi app. Any help would be appreciated!
ive read somewhere it seems to be a known issue with BLE midi and mac .....problem comes from how mac handles this devices , I ignore if its still unresolved today...
@@ryokosaka8859 hmm, maybe you could switch on an led when a signal is triggered by the esp and then hold everything next to the window with the daw and film everything on one take. Then you could measure the amount of frames that pass between the led changes its state and the daw receiving the Midi signal. It's not accurate but it's the simplest way I come up spontaneously. It is only accurate to +- one amount of frame and the time the led takes to switch on or of. So +- 17ms for 60fps. The measurement then could be repeated to see how stable the latency behaves. It's a lot of work though I imagine. However, the latency is very important for the real life applicability for musicians, especially drummers. A total latency (hit to sound production) around 10ms would be really neat to achieve but I don't know if it is possible with BLE in the communication chain. I find it very inspirational that you just put this project together without much overthinking it seems. I feel like I block myself by overthinking every little detail and then not getting started at all. Oh another idea which could be more accurate, you also measure sound when you record the demonstration. So if you can distinguish the hitting sound and the created sound you could measure the time difference which is the total latency. The loudspeaker position and the hitting position should be at the same distance to the camera's microphone. The resolution would then be how good you can find the beginning of the signals +- one divided by the sample rate e.g. fs = 48kHZ -> Ts = 0.021ms. Sorry for my unstructered thoughts and keep up the good work!

@@ryokosaka8859 I have made MIDI2CV with ESP32, I was playing sequences from Bitwig Studio and sound output were going back to Bitwig with HW Instrument. There is an ability to measure delay. When I was using USB MIDI2CV it was around 7ms, while with this experiment on ESP32 through BLE it was from 30ms to 40ms. So it is significantly slower, but still playable.
Hi - thanks you very for library , but i got general problem with ADC usage on wroom 32 esp - adc converters just don't work - i cant use potentiometers in my MIDI project. Any sugestions ?
What is the thing you click on the top right corner to access the Bluetooth options? I am looking at Bluetooth devices on a Mac also, but the device never appears. Am I doing something wrong?
The notification in the upper right corner is from KORG's Bluetooth MIDI Connect. My MacOS version is Catalina 10.15.7. apps.apple.com/jp/app/bluetooth-midi-connect/id1074606480?mt=12 I just followed this guide for BLE connection. www.korg.com/us/support/download/product/1/305/
Dear Sir, can you check this setup with some IOS device running GarageBand? I can connect the ESP32 running your code example to iPad via BLE, but this produces no sound. When I connect the same thing to Android device, it works, but unfortunately the lag is unacceptable (Android fault, of course).
@@ryokosaka8859 I've just run thru the menu and used the native garageband option to connect a bluetooth midi device. Almost like this ua-cam.com/video/xOMa0RuzQqI/v-deo.html . It shows "connected", but no notes are triggering. Now I see thet you've used KORG's thing, so I will try too. But I believe that some DIY projects were able to connect and play natively. Just couldn't find the right video. Thanks
@@copych I've just tried it. I was able to connect from garageband settings without using the korg app. In the same way as the video you told me. I'm trying out the test code and it's sending a MIDI signal with no problem. Have you modified any part of the test code?
@@ryokosaka8859 I used the original sample code that goes with the library, SimpleSensing_BLE_MIDI unchanged. Maybe the iPad is too old =) I ve got iPad mini v1 i think

Love your Arduino Open Drum Project as always
I love your HelloDrum library!

is there any delay when sending midi via bluetooth esp32? which do you use for sending midi, bluetooth or wifi..

do you think this will work with an iPad?
Somebody knows why that library doesn't work on my esp32 devkit v1? The Bluetooth device never shows up on android or laptop.
how do you
pair the bluetooth? i
tried
and could see any midi signal coming from the board
Great projects! Can you estimate the latency between hitting the pieco and receiving the Midi signal in th DAW?
Thank you. I'm going to try it out eventually. Is there an easy way to do it?

If we make two of them, they can communicate together ?
