Hello,
my board just arrived and I wanted to try the organ out.
But I'm little lost with all the configurations and platforms. Do you have any tutorial on how to get this working on this specific board?
Thanks :)

While building the organ sample, I needed a test file and so I used this midi file.

I drive the RPiPICO via USB from a midi player running on Windows.

The RPiPICO will crash/lockup once the midi data becomes heavy and relentless. Power cycling is the only option.

TBH: I’m not surprised. I’m more curious if the ML_SynthTools (and/or example code) should fail gracefully by dropping notes or some other behavior vs crashing completely and requiring a reboot.

Hello.

I'm playing with ml_synth_organ_example using EPS32-S3 based ESP32-S3-DEV-KIT-N8R8 board from waveshare.

I've successfuly managed to use MIDI-IN using 6N138 and PCM5102A DAC and I have much fun plaing with it.
However, I have a problem with scope. When I define OLED_OSC_DISP_ENABLED, compilation fails with the following message:

undefined reference to `ScopeOled_Process()'
collect2.exe: error: ld returned 1 exit status
*** [.pio\build\esp32-s3-devkitc-1\firmware.elf] Error 1

I'm using vscode + platformio. My platfomio.ini file is:

[env:esp32-s3-devkitc-1]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino
upload_port = com11
monitor_port = com11
monitor_speed = 115200
lib_deps = 
	adafruit/Adafruit SSD1306@^2.5.7
	adafruit/Adafruit GFX Library@^1.11.7
	https://github.com/marcel-licence/ML_SynthTools.git
	adafruit/Adafruit BusIO@^1.14.1
build_flags =
        -L"${platformio.lib_dir}"
        -lML_SynthTools

I'm comiling code using esp32s3 variant of precompiled SynthTools library by
placing ML SynthTools\src\esp32s3\ML_SynthTools.a file in "${platformio.lib_dir}" folder and renaming it to libML_SynthTools.a.

Am I doing something wrong or is it possible, that ESP32-S3 version has no scope support compiled in?

Best regards,

In ml_synth_organ_example.ino

There is a compile error if you don't have MIDI_TX2_PIN defined (i have the RX pin defined) because in the midi module this Midi_SendShortMessage ... is reliant on the #ifdef MIDI_TX2_PIN so I added that to remove the compile issue as I am just adding the USB_Midi_host hardware and testing

#ifdef MIDI_VIA_USB_ENABLED
void App_UsbMidiShortMsgReceived(uint8_t *msg)
{   
    #ifdef MIDI_TX2_PIN
    Midi_SendShortMessage(msg);
    #endif
    Midi_HandleShortMsg(msg, 8);
}
#endif

Hi,
the organ sound great!
Do you know why i have this issue? I added the board as described here:

audio_module:118:13: error: expected primary-expression before '.' token

Thanks

Hello! Just tried compiling this for a generic ESP8266 board but received the following error:

I'm new to Arduino so any advice is appreciated. Thanks!

edit: Closed - I downloaded ML_SynthTools from master instead of v1.1.0 release.
