    • RE: Mozzi sound synthesis library for Arduino - how to make it work on the Core2

      @rodberry said in Mozzi sound synthesis library for Arduino - how to make it work on the Core2:

      @oscillator congratulations Staffan, I'm a year late to the party but just wanted to say this is a lot of fun and I really appreciate the thorough documentation and the very readable code (speaking as a C-phobic beginner programmer).

      I'm planning to make this into a module for my AE format modular synth. For now, I'll start by just feeding it into a converter but will eventually get the other components organised to make it work nicely in the system with my other modules. At least you have given me a nice wagon to fall off! :)

      Cool, I am glad you find it useful! The AE modular seems great.

      I can also recommend the Daisy Seed, for which I've done a few projects:

      Good luck with your projects -- and your music! :)

      @raychmond said in OscPocketM - portable beat production tool for the M5Stack Core2:

      Never mind. I found out that my M5core2 library is too old. After updating to the latest version, it uploaded successfully.

      Thank you anyway!

      Glad you got it running! Happy beat-making! :)

      Arduino/libraries/Timezone/src/Timezone.h:16:66: fatal error: TimeLib.h: No such file or directory

      Hmmm, found this: https://forum.arduino.cc/t/timelib-h-no-such-file-or-directory/413110/4

      I know they talk about Windows, and you run OSX, but maybe this applies to you too?

      You seem to have prepared everything that they want...

      Documents/Arduino/libraries/Timezone

      Do you have the Timezone library installed?

      In the docs for the Timezone library it says:
      "The Timezone library is designed to work in conjunction with the Arduino Time library, which must also be installed on your system."

      There is also a note in the beginning of the code:

      // !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
      // !!! Library versions should match to mentioned below !!!
      // !!!!!!!!!!!! Otherwise code won't work !!!!!!!!!!!!!!!!!

      Do you have the right version of the libraries installed?

      @pirix said in Librerías ESP32 vs Arduino:

      Yes, I did. M5Stack-ESP32

      Strange. Can you post the whole output of your compilation? Maybe there is some earlier error.

      What OS are you running?

      @pirix said in Librerías ESP32 vs Arduino:

      Cómo solventar este problema de librerías entre Arduino y ESP32?

      When I compile for the Core2 I also get warnings, eg:

      Multiple libraries were found for "SD.h"
      Used: /home/staffan/.arduino15/packages/m5stack/hardware/esp32/1.0.9/libraries/SD
      Not used: /home/staffan/Arduino/libraries/SD

      but that doesn't stop my compilation.

      Have you selected the right board in the Tools menu?

      I've got audio output using the DAC to work now so it is easy to output the sound to a speaker or mixer. The instructions are in the updated PDF manual.

      Welcome to the OscPocketM (OPM) - the portable beatmaker for the M5Stack Core 2!

      0_1631992428075_mtitle.jpg
      In your hands you will have 3 synthesizers and 1 drum machine that all can be sequenced and used to produce songs.

      The synthesizers have selectable waveform, a low pass filter that can be modulated, an adjustable envelope and an optional second detunable oscillator.

      The drum machine has seven sounds: kick, snare, open and closed hihat, clap, tom lo and tom hi. All sounds can be tweaked.

      All sounds can be balanced using the built in mixer.

      The synths have a piano roll step sequencer and the drum machine has dedicated 5 track step sequencer.

      Sequences can be chained using the song editor.

      There are also utility functions for saving and loading setups and sequences, as well as copying and clearing sequences and settings gate times.

      All software is running on the Core2 including sound generation using the excellent Mozzi library.

      @oscillator looking forward to try it 👍

      Thanks a lot @AgreeDK, just a few more days and it will be finished! :)

      Last thing on the list is data save/load (maybe even MIDI export), sequence copy function, demo, manual. Then I will release the project under a GPL license.

      Song mode (arranging sequences in programmed order)

      and a primitive though useful mixer for the three synths and all the drum sounds!

      Here is the main menu. The engine is running three editable synths and a 5 voice drum machine (kick, snare, hihat open/closed, tom hi/lo, clap/crash).0_1631826372496_main.jpg

    • RE: Core2: Using the second core

      Excellent article, thanks a lot @AgreeDK

      My plan (in the future) is to have the sound lib Mozzi run on one core, and the UI on the other.

    • Core2: Using the second core

      Hi all,

      when I run an Arduino program, does it only run on one core?

      How do I utilize the second core of the processor?
