Glad it helped!

Thanks a lot, will do!

agree. Content of this topic is very very limited on youtube witch makes it a bit harder to figure out, an learn. Thank you mo_thunderz for doing this!

Thank you so much!!

Glad you liked it!

Thank you very much for this addition! I have added it in the example code online.

Thank you for your feedback. Yes, of course you can connect a water sensor, or any other sensor, to the Arduino and interface with that. Just make the water sensor work first with just the arduino and after that send information from the sensor through the interface to Ableton

It is a bit tricky debugging like this, but the one common mistake is that the serial port is already "taken" on your PC. If you load the M4L plugin in Ableton, make sure you dont connect that one to the serial port if you want to open the M4L editor. Then in the M4L editor you should be able to connect to the ESP32. Did you try to run the final code I shared on Github? That should work... Good luck with your project!

@@mothunderz hey! In the meantime I figured it out and managed to build my own custom patch for automation with sensors, it works :)

That sounds to me like a "Max-for-live" problem. There are many ways to solve it. You can for instance only send a new value when the value changes and keep that value locally in your Teensy to show on the LCD screen. If you want to solve the problem in max-for-live, I recommend using the "print" function a lot to see where the highest value comes from. My bet would be that the knob in ableton needs to be triggered to give the current value with a ping or something like that. However, that is a bit tricky to say without seeing the code. Hope you can figure it out!

I have not tried with Ableton Intro, but as long as it includes Max for Live you should be fine.

I have not checked lately, but the Ableton Arduino interface that I use here was not fast enough for passing audio. I have not checked though what additions were added since about a year.

Sounds like a fun project to me. First of all: a MIDI file itself does not contain a sound. A MIDI file only has the information of which note is played when. For your project there are many ways to realize it, it really depends on what kind of sound you want to have. Here some options: 1) you can make a VCO (voltage controlled oscillator). This is basically what old Synths are based on. The tone goes up with higher voltage. However, just a VCO might not be too pleasant to listen to in the long run. The sound of just the VCO can be quite dominant. 2) you can create a sound from the ESP32 directly. However, this also will be just a simple sine, square wave or so. Also this might not be too pleasant to listen to 3) you could use a sampler and upload a .WAV file to it. Then you can play that sample at different speeds -> different tones. The best platform to do this on is Teensy, not ESP32, but I googled a bit and it is possible to do it on the ESP as well: ukposts.info/have/v-deo/mWlkaq2FnqqUs3U.html Hope this helps. Good luck with your project!

@@mothunderz thank you for the reply! I have considered the option of using a sampler with a wav file and using a pitch bend, that might create the effect similar to what I’m looking for and would allow for testing lots of different sounds I would LOVE to be able to replicate the wonderful synthesized motor sounds I found in a really awesome app called OTOTETSU, which synthesizes different types of real and imaginary sinusoidal motors (definitely worth checking out). My idea with using MIDI was that I could feed my favorite motor sound from that app into a program that would map it into a series of Midi notes, then I thought I could play through that “scale” with the throttle signal on the bike. I imagine all this would take some work though. Still not 100% sure if the ESP32 would be able to play those MIDI files as sounds, seems possible though? I already emailed the developer of OTOTETSU, and while they said they really enjoyed the idea, they weren’t able to provide any sound files or MIDI files, which is why I considered feeding the sound into a program to map the sound into a series of MIDI notes.

I dont fully understand the setup you want to create. But yes, the ESP32 can of course create MIDI notes. The easiest platform for midi is Teensy IMO, but ESP works as well. Pls post a video if you manage to make this device :-)

Yes it does, I use Ableton 11 myself as well in the meantime.

@@mothunderz Oh! Thank you !! ;)

Hi Max, you could in essence use the code of my ADSR+LFO below. ukposts.info/have/v-deo/gJxoopWGmX1kqKM.html Github: github.com/mo-thunderz/ArduinoAbletonLfoAdsr This is synced to Ableton and by either using the sync output or setting the ADSR to block shape you can directly control your LEDs. However, the code as is is written for the DUE as I was using its DACs. For LEDs you definitely dont need to use DACs and you can just use any PWM port. The adaption to standard PWM ports is relatively easy: // Code optimized for Arduino Due as it has a built-in DAC // For use on other boards just reduce the DACSIZE, // remove the analogWriteResolution(12) statement and write // to a different port for all analogWrite statements. But the code is a bit of an overkill as you wont need all these features. Let me have a look and I'll post some code focused on controlling LEDs soon.

Made it easy for you, here is the code for just LED control: github.com/mo-thunderz/ArduinoAbletonLed/ Will add a UKposts video for explanation as well next week.

@@mothunderz WOW! thank you so much. you put some much time into this. What i have done is. i have made a M4L device with toggle buttons. each buttons is sending there state via serial every time it changes state. And the state of the buttoms is controled with creating a square-wave in automation in the timeline. Ableton is hooked op to an UNO that read all the serial data. and sendes a pulse to an EPS32 equal to the square-wave cooming from the serialport. The ESP32 is then controling a LED strip configered in a matrix. the matrix will draw things based on, where ableton is in the timeline. and i can follow ableton because it is reading a pulse from the UNO that is created from the M4L device and send to the UNO via serial. The onlt problem im having is that, the EPS32 dont know where in the timeline ableton unless. The timeline in ableton and the ESP32 have been reset exatly at the same time. does it make sense? Maybe there is a smarter way to do it. i just havent figured it out yet. sorry for bad english. And thanks a lot for your help and advice.

Is there a way to make the M4L device send out a number that is porpotinal to the timeline? e.g. (bar 1, beat 1) = 1, (bar 1, beat 2) = 65, (bar 2, beat 1) = 257 and so on. does it make sens?

Why would you put an Arduino in series with an ESP32 and not communicate to the ESP32 directly? You can of course send information from Ableton with a push-button as well, but pls have a look at the LED control code I posted. In the M4L device you can see that I am sending the bar count and beat count to the serial port. Thus in my Arduino/ESP32 I get the exact location where Ableton is and use that to control some output ports. I hope you understand what I mean, but in case not, pls give me a few days, will upload a description video of the LED code.

@Soundprayer: hi, there are various ways to implement that, but the easiest way is to just send them sequentially. Please see this video in which I send various parameters from Ableton to the ESP32: ukposts.info/have/v-deo/jXN8ipufboSBqZc.html Another code example where I send very many parameters at the same time is here: ukposts.info/have/v-deo/gJxoopWGmX1kqKM.html Cheers, Sander

@@mothunderz thank you, ill try

@@mothunderz I did it - every value with different control bit. But - when playing automation from ableton, sometimes lights "jump" to different values for short time and blink. It happens in places they shouldn't. Had you same experience?

@Soundprayer, from my experience, especially the Max For Live (MFL) part can be tricky to work with. If you see lights jump does MFL send out a comment to the Arduino or not? If it does then you know you have to debug the MFL code, if it does not, then it is the Arduino code you need to look into. There is one bug in MFL that you also need to take care off. This bug I describe in the video below from 11:22 through 17:40. Especially when you are changing many parameters at the same time, this is essential. ukposts.info/have/v-deo/gJxoopWGmX1kqKM.html So, pls carefully observe what MFL sends out to the Arduino at the time of the glitches and make sure you dont overload the serial interface with gating (as shown in the video). Hopefully you will be able to find the problem. Good luck!
