Hi Marcel, here the public start of a discussion. As I already tested some Audio-Libraries with the ESP32, ESP8266 and the Teensy. I was impressed by the good sound-quality of the Drums. As I don´t have the right MIDI-Controller with the implemented CC to test it, I decided to copy Your Repository and modified it a bit to get a way to trigger the samples with a keyboard. I removed the Sequencer and added a standard Arduino Midi Library to make it a bit more readable for other developers. You did a great job. As I had tested the ESP8266 Audio Library from Earlee Phil Hower and the Teensy Audio Library, - I would say, Your Arduino Sketches provide the best Price/Sound-Ratio. To make it easier for other developers to use Your sketches, try to use the Arduino MIDI Library which works well with the ESP32 on serial ports too. My modified code is here:
As Your are updating Your Code with bigger steps, I believe my version will be "old" in some weeks. |

Hi, I'm using a variety of devices. I'm an ex-musician and software developer. I've been out of it but got back into arduino/microcontrollers. I bought this Esp32-A1S-audiokit 2.2 board and I want to create my own processing, spectrum analysis. I've already got some projects i built up that do spectrum analysis on an ESP8266 and use it to do a VU of 8 neopixel with color related to frequency and amplitude. I've got various midi-devices and would be more than stoked to be able to modify and extend software related to sampling keys, synth etc. Yes, start from a sine wave. I'm also building a lot of amplifier, eq analogue circuits. Headphone amps - so I'm interested in i2s audio and DAC so I can perhaps eventually have onboard dac and filters DSP etc as part of a headphone amp box that links directly to something digitally Ok - i got it to compile and load - now I got to figure out the rest of the implementation or a test harness. So now i'm moving over the midi USB host SLR Development Module MAX3421 type thing. So basically I'm looking for the hardware side of what you have going on over on another youtube. |

Thanks - I got a few of Marcel's projects to compile on my ESP32-A1S board ... now I'm looking at either copying with the same basic ESP32 and I've got the USB-HostShield. However, reading the code for this project it seems to read midi from Serial2 which it sets up on RX2/TX2 so I'm trying to figure out a basic test to see midi flow in from USB host with a launchpad plugged in. I suspect though that maybe that is just an output for lights ... looking at the video. Anyway. Yes - i'll try this first as he has done with same hardware and later I'll try to run it on an ESP32-A1S with its AC101 dac if possible. I saw him using one for other projects. |

Regarding the USB-HostShield, I used it for MIDI in and out. Different configurations are possible |

Isn't there a headphone jack already soldered on your pcm5102 DAC?

So, lets assume that your DAC uses i2s ... since you didn't specify at any point b ut people kind of assumed you had a pcm5102. So to ask for what pins without even mentioning what you are trying to connect is a very hit and miss way to ask for help. We might tell you the wrong thing - but what I can tell you is that you are using i2s if you are using Marcel's audio projects so you can find the wiring info within this and ... well you might take time to read through it if you are new to this protocol. What I can tell you is that one of Marcel's videos has a wiring diagram and that was where I found my way when all this was new to me and I also hadn't used i2s or a DAC before like this. I could dig that up but when we do this stuff for fun or other reasons we have to learn to find datasheets and guides just by googling until we have the stuff that works. However there are 3 pins in that guide ... and there is no danger if you get them wrong, just put them in correctly and power your DAC etc with the right voltage ( probably 3.3v is fine). Good luck, i've been banging away starting from nothing much till I've built a few of these synths and made my own designs. It takes a lot of patience and "one step at a time". |

You can find out the pinout of the DAC via the Code too. I have great respect for Marcel's work, but you also have to do something yourself. Otherwise nobody would start a OpenSource-Project. I have found the schematic in a few seconds .... |

I also have not found that diagram easily, it took me at least one month to
accidentally fall on it by accident and it was not actually working for my,
seemingly identical setup.
I also have extremely great respect for all the efforts, time and love that
Marcel put in these projects.
I also understand that it might be easy or seem like it's so obvious for
people with previous knowledge and a great understanding of c++ and coding
in general, but for people like me that have only a self-taught knowledge
and been using code for a few years, or months only.
It really isn't that obvious at all.
I have been trying to understand the workings of marcel's code for the
better part of the past two years and I still am barely able to write my
own very simple code.
About Marcel's pinout diagram
I had this working with what I thought was the same breakout 5201 and esp32
but no, I found a different pinout which was working for my models (which
look identical as Marcel's pictures) so it's really a tricky thing I'm
finding out with i2s and pcm DACs...
I am now able to run every code from Marcels libraries, but unfortunately
for me.
The volca beats mod still produces no audio for me.
It's really not as simple as experienced coders seem to think so. I'm a
musician and video editor, code has not been part of my life before 2 years
ago.
I'd be glad to offer any help I can or that you need to help with a proper
wiki.
Let me know Marcel!

Merci Fabien. So far, i've reach a vague understanding of code, buidling a MODEP pedal effects with a PI, a MIDI Hub with another PI, and a drum Pad with an arduino I've started soledering with the Korg Mini Pops Arduino project (in order to get that Oxygene-equinoxe feeling). Regarding This drum computer, what i'd like to do is a kind ol Linndrumm emulation, using samples of this machine. If i manage to do so, you can be sure that i will write a Instructables for the very noobs like me ! |

@fabiendostie Its really cool that you share your difficulties - yes some know how to find their way around these repositories to the diagrams. I've been doing this almost like a daily job, but hobby, for quite the best part of a year. I have a degree in Computer Science but I hadn't been really writing code for a long time. C++ is very prone to bugs - it is for me the language I was most familiar with so. I learned to program when I was 10 and I am 53 ... so I have confidence I will get there but I admit there was a lot of prep to get anywhere. The first board I had was the Esp32-A1s audio project board. I ended up making it play some mp3s before I got into the synth projects. I gave up and went to a based esp32 and the same DAC as Marcel used in one of his videos to make things as precisely the same. Since then I have made a lot of variations and my own forks have extra modules for managing keyboard (switch arrays), arpeggios, midi. Sometimes i have had this ongoing shitty bug with USB midi that comes and goes. Recently i opened up the midi keyboard and cleaned it and put the rubbers in position better - removed dog hair that somehow found it's way inside. Then things worked a little better. When anything doesn't work - like no sound do you really try to find the simplest way. Then - if one project makes no sound try another like the Basic Synth project was the one I worked the most with and then it has that test note #define variable to trigger a note. There is #ifdef NOTE_ON_AFTER_SETUP in some of the newer projects. Finding your way around those #define conditional inclusions/exclusions of that code was something interesting I hadn't seen in a lot of projects. section and trying different values. The first time I fired up a project it was really making terrible sound because I had too much going on slowing down the loop that feeds samples to the DAC. There are always a few basic audio projects around that one can try to prove to oneself that the DAC works if getting any sound is an issue. I'm sure many of us were there at that shakey start. |

I guess my writing was not clear enough, my language is french normally. That one does not work I tested the DAC tested the boards, tried different variants... It does compile but no sound. I'm 100% positive esp32dev kit and 5201pcm DAC are both working because they were tested...Today! |

I have been fiddling around with microcomputers and stuff for 5-6 years it's not so new to me but I'm not a big fan of code, I'm getting there slowly but... I'm 46 it's not as easy to learn this types of stuff now! |

The bit count is used to configure a specific resolution. It is used to select the bit count of the variable which is used to playback the waveform. In case of 10 bits a sample will be stored in 1024 samples. I do not calculate values in between that makes the code faster but consuming more memory. WAVEFORM_Q4 is used to get the length of a quarter of a waveform. WAVEFORM_I is doing some magic. You can input a 32bit value which should overflow with the same rate of the desired frequency. For example to generate a 441 Hz tone using a sample rate of 44100 Hz you will need an overflow of the value 100 times a second. |

@marcel-licence so you did a lot of experiments how to scale waves at frequencies and avoid overflow errors. Every little bit of explanation helps me to make progress figuring it out but in truth I'm still working on so many parts of a physical interface and display. Once I have more controls then slowly I work through other projects and then finally start to look at extending functionality. |

All Marcel's project compile and work perfectly with all my esp32 A1S v2.2 And all the various variants of esp32 8 have some with DAC's some without. My issue is with the forked version of the Drum machine, the one that has integrated it in a Volca beats:

Hi Fabien,
the Code which You mentioned was not based on my code…
You took the code from marcel and modified it.
Your Answers don’t belong to my code.
Sorry…

You used Audio.h
.. my version, which was based on code from Marcel from 2021 doesn’t use Audio.h.
I don´t have the time to check Your code.
Excuse me.

That's quite rude of you to first offer me help but then just say, that without even looking at the code!! YOU asked me to upload my code and that you would take a look?
Obviously, I started with your code but I modified the pins used to make it work with my specific DAC, but that is only the pinout and naming scheme that was modified.
It's IS 99.999% your code I did not use marcel's code, I was just desperately trying stuff out to maybe make it work with my i2s DAC and I guess I forgot to remove that "#include "Audio.h” line from your code I’m sorry.
I DID have to change the pinout and naming scheme of the i2s interface to fit my I2S DAC to work… It did not work at all with your original code, It actually wouldn’t even compile!!!
All the rest is 100% your untouched code. And it is NOT working on 2 other different setups (i2s DAC’s + esp32’s) I’ve tried, even though I’ve tested the DAC’s and the board’s with other codes like all marcel's synths and samplers for example, which all work perfectly. And have audio coming out.
I really think there is something wrong there is with your code+my dac+esp32: it’s definitely not easily applicable to other people than your exact setup it seems. It seems that it is only applicable to your exact brand and model and that it doesn’t work on any other that I've tried (I tried 3 different combination of brands and makers!!)
that’s why I’m asking for your help because I've been trying to make it work for a WHOLE YEAR now!!!
Actually drilled holes and installed pots and everything! (I know I should have tested your code before, but since it was based on Marcel’s code I figured It would work as all of his code works with no issues!!!)
Please would you be kind enough to take a quick look and hopefully find something that might be the cause of it not producing sound?
Please would you, I really am desperate by now.

Hi Fabien,
Download my repository „ESP-Audio_Test-ML“
Unzip it
go into the folder „ESP-Volca-Beats-PCM-MOD“.
Open the File „ESP-Volca-Beats-PCM-MOD.ino“ in the Arduino IDE
Upload the folder „data“ using the LittleFS-Tool.
I checked it 2 minutes ago with the same code from the website.
I have used a simple ESP32-DEVKit-Module…
If You have to change the Pinout for the PCM5102-Module, change the Pins in the Code of the File „i2s_interface“ in Line 17,18,19
I didn´t test the code without the I2S-Codec…
If this doesn’t work on Your side, then take the newest code from Marcel und ignore my code. take the MIDI-Notenumbers which I took from the Volca-Beats MIDI-Implementation and do Your own implementation.
Which I2S-DAC did You use?
Which Pots did You use, because I used 3 Potentiometers to control the Filter and Bitcrush and Sample-Speed.
If these are not connected You cannot hear anything because the Filter will kill all - as a Lowpass or Highpass.
Sorry, i did not work with the code for a year now.
My Setup is simply the ESP32-Devkit and a PCM5102 DAC wired as described by Marcel.
I am really not hiding any secrets!!
I will take a second look at Your code …
Regards
Erich

Hi Fabien,
I have tested Your code but swapped the i2s_interface back to my version.
It compiles and works.
Perhaps You could try to get a simple PCM5102 - DAC.
I cannot help more because I do not own the same DAC which You have used.
perhaps it is a problem with the conversion from Float to Integer.
In my code, the Pinout for the DAC was defined in the i2s_interface.ino.
In Your code, it was defined twice, once in i2s_interface.ino and in the ESP32-Volca-Beats-PCM-FABMOD.ino.
This is perhaps bad for Your DAC.
As I don´t have the same I2S-DAC as You mentioned, I replaced the i2s_interface.ino back to my version.
If You are using another DAC, You have to change this file to get a special version for Your DAC.
As it is difficult for others to follow us, - Your and my code is different to the code from Marcel.
perhaps it would be better for You to create Your own repository on Github to discuss it there.
To get Your version compiled and working, I only disabled all the lines of code for the „Audio“ - Setup for Your DAC and replaced i2s_interface.h with my version from my GitHub-repo..
My Code is slightly different to the code from marcel, he did not use any MIDI-Library. My Code uses the MIDI-Library from FourtysevenEffects! perhaps You have to install this to get it compiled.
Best Regards
Erich

All the rest is 100% your untouched code. And it is NOT working on 2 other different setups (i2s DAC’s + esp32’s) I’ve tried, even though I’ve tested the DAC’s and the board’s with other codes like all marcel's synths and samplers for example, which all work perfectly. And have audio coming out.
I really think there is something wrong there is with your code+my dac+esp32: it’s definitely not easily applicable to other people than your exact setup it seems. It seems that it is only applicable to your exact brand and model and that it doesn’t work on any other that I've tried (I tried 3 different combination of brands and makers!!)
that’s why I’m asking for your help because I've been trying to make it work for a WHOLE YEAR now!!!
Actually drilled holes and installed pots and everything! (I know I should have tested your code before, but since it was based on Marcel’s code I figured It would work as all of his code works with no issues!!!)
Please would you be kind enough to take a quick look and hopefully find something that might be the cause of it not producing sound?
Please would you, I really am desperate by now.

Hello sir!
First, thank you for this answer.
That is exactly what I did (downloaded your code from exactly that GitHub
repo, I then only modified the name of the i2s pins which I discovered have
to be different on my model of WCMCU DAC (PCM5102) and also the pinout is
slightly different. But other than that all is 💯 your code.
So I did EXACTLY as you just wrote and followed your how- to very
precisely. The only difference is the pinout that I changed in the
i2s_interface.ino file in Arduino IDE obviously.
Also I have discovered to NOT do the solder bridges you are mentioning in
your "how to guide" for it to make sound (tried many other sketches to make
sure it works)
BUT, the pits aren't wired right now, so this gives me hope that this could
be the solution to my problem. Would make sense since I'm using the same
board and DAC as you are!
I'll let you know how it goes.
Thanks again!!!

Hi Fabien,
I have tested Your code but swapped the i2s_interface back to my version.
It compiles and works.
Perhaps You could try to get a simple PCM5102 - DAC.
I cannot help more because I do not own the same DAC which You have used.
perhaps it is a problem with the conversion from Float to Integer.
In my code, the Pinout for the DAC was defined in the i2s_interface.ino.
In Your code, it was defined twice, once in i2s_interface.ino and in the
ESP32-Volca-Beats-PCM-FABMOD.ino.
This is perhaps bad for Your DAC.
As I don´t have the same I2S-DAC as You mentioned, I replaced the
i2s_interface.ino back to my version.
If You are using another DAC, You have to change this file to get a
special version for Your DAC.
As it is difficult for others to follow us, - Your and my code is
different to the code from Marcel.
perhaps it would be better for You to create Your own repository on Github
to discuss it there.
To get Your version compiled and working, I only disabled all the lines of
code for the „Audio“ - Setup for Your DAC and replaced i2s_interface.h with
my version from my GitHub-repo..
My Code is slightly different to the code from marcel, he did not use any
MIDI-Library. My Code uses the MIDI-Library from FourtysevenEffects!
perhaps You have to install this to get it compiled.

You do understand that I have exactly the same DAC PCM5102, esp32devkit v1,
the same midi libraries installed and that I followed every step of your
guide which is in your repo with the code?
Also that it is compiling and sending midi out which I can read on the
serial monitor if the Arduino IDE.
So my guess is that it's either an issue with LittleFS since, as Marcel
mentioned, it's reading the samples directly from littleFS, and I suspect a
problem there or the potentiometers not being hooked.
I'll completely re-install littleFS tools and solder the potentiometers to
the board, they already are glued and installed and wired in the Volca
just not to the esp32.
If after all those painful efforts and long nights it still doesn't work.
I'll give this up and concentrate on modifying Marcel's project to work
with the Volca. But it'll be hard for me, I'm tenacious and I want to
learn! The learning curve is really steep for me as I'm from a really
different background but I'll succeed in the end. I'm real patient and
tenacious ASI said.

What does appear in your arduino output when executing the "ESP32 LittleFS Data Upload"? Please ensure that verbose output is activated that helps finding the issues |

It was saying upload successful, but also that the folders couldn’t be created … and I updated the littleFS then everything broke… couldn’t upload anymore. I really don’t know what is happening! I don’t think I’ve ever had so many problems with any project, it’s crazy like I’m cursed on that one!
I am in the process of re-installing it, but I’m apparently having issues, looks like it’s related to python 3.9 is the version I’m using but Arduino is using python 2 or something, ill keep you guys posted for sure… I’m onto something now…
Hopefully soon ill be able to re-test again...

If Upload with littles does not work:
- Check the ErrorMessage
these are the 2 known problems:
1. Serial Monitor is active and blocking access to serial port
2. You have to format littleFS first > ESP32 Sketch Data Upload - Menü „!Erase Flash!“
3. Little FS isn’t well installed.
In Your case, concentrate on 1 and option 2.

Hello again sir, Obviously, the serial monitor isn't running while trying to upload using the serial port ;) The thing is that I do have it installed (pySerial and serial), but on my python3 path, since python2 is deprecated, I can't install it using something like: git cloned : LITTLEFS-master I have just spent the last 3 hours on stack overflow and other sites to try to find the way to tell Arduino IDE to look for Serial but in the Python3 PATH, many different suggestions, but none worked because as I said, I have Pyserial installed on python3.9 and it won't let me install it on python2.7.... where Arduino looks for pyserial etc... etc... etc... None will work... Maybe someone here has the solution for me. I realized that this is really a problem that a LOT of people have, i could go for hours reading Reddit , blog posts, stack overflow and Arduino board etc... many are Offering supposedly THE "solution" but none of the 20-30 ones I've tried had any positive effect on my situation... why does it have to be so complicated for this project, I<m telling you... it feels almost as it's cursed for me! lol! I Am going to, eventually see the end of this... soon hopefully!!! Open to ANY suggestions really... thanks again |

hahahah, as i wrote it IS installed... its arduino that is looking for it in the wrong folder (/Library/Developer/CommandLineTools/usr/bin/python3. ) I have no clue as to why it looks there... I have no idea why arduino doesn't see it installed along with python3 in that folder!! look its right there!!

Sorry I couldn't be more helpful - maybe fix your python install completely. I upgraded linux and it broke my python install but I fixed it with that command. I don't put myself forth as an expert .. just share how I connected the error message and what ultimately worked for me. I could write more - like i 'pip install serial' and i got a different error message to uninstall that (inside arduino trying to compile) and advice in there to instead install pyserial ... then I was able to finish and upload to the board. I got sound, i got the metronome tones now I have to figure out how to even use this. |

Thanks, I am thinking about actually completely removing python 3+ (because mac needs the pre-installed 2.7) and ArduinoIDE... Thanks for the help @MichaelPNolan |

I don't have any extra diodes on my implementations of midi interfaces ..
yet, but probably will add if i make a printed circuit.

Sehr gerne, you are welcome.
I tried to explain the usage of the components. It should work without the
diodes.
Does the description help to understand why there are two voltages?
Otherwise an update of the description is necessary.
You can try to apply ~3V for both.

I had similar errors I'll put some info in near future. I installed
pyserial ...

I also, of course, had formatted the flash using the tool prior to
uploading as it's the procedure and I always read all the documentation
before starting to use a new tool.
that is precisely why I had put the blame on LittleFS, actually on me
having NOT installed it correctly.. but now... it's even worse!!!
These littleFS errors are new because I have been able to upload
successfully for the last 2 months at least, they weren't happening a few
days ago, but I did update a bunch of stuff in Arduino, trying to help my
problems turns out I made them worse.
I removed the littleFS install and started the install process from
scratch. all went well except... I still get this error about Pyserial!!!
The thing is that I do have it installed (pySerial and serial), but on my
python3 path, since python2 is deprecated, I can't install it using
something like:
pip2 install Pyserial Serial
git cloned : LITTLEFS-master
got: LittleFS_esp32, mklittlefs, the littleFS-tools, arduino-esp32fs-plugin
got the files in /Applications/Arduino.app/Contents/Java/tools/

I have just spent the last 3 hours on stack overflow and other sites to
try to find the way to tell Arduino IDE to look for Serial but in the
Python3 PATH, many different suggestions, but none worked because as I
said, I have Pyserial installed on python3.9 and it won't let me install it
on python2.7.... where Arduino looks for pyserial
for example, i tried so many commands here are a few of them:
sudo pip install python-is-python3
or
ls -l /usr/local/bin/python*
ln -s -f /usr/local/bin/python3 /usr/local/bin/python
exec $SHELL -l
or
brew install pyserial
etc... etc... etc...
None will work...
and this is the IDE output:

Maybe someone here has the solution for me. I realized that this is really
a problem that a LOT of people have, i could go for hours reading Reddit ,
blog posts, stack overflow and Arduino board etc... many are Offering
supposedly THE "solution" but none of the 20-30 ones I've tried had any
positive effect on my situation...
why does it have to be so complicated for this project, I<m telling you...
it feels almost as it's cursed for me! lol!
I Am going to, eventually see the end of this... soon hopefully!!!
Open to ANY suggestions really...
thanks again

thank you very much for the quick reply. I will investigate the cause more closely and tell you later what it was :) |

I was able to determine that it is due to the encoder: wow, now i understand why spiffs-lagacy should not be used :D especially when playing several samples it is very noticeable ! |
