I am going to make a electric drum similar to this https://www.youtube.com/watch?v=rFBDFAEcbjk&ab_channel=CajonMaster

I made a prototype but I could not make the actual sound. I dont want to use MIDI or Drum sample audio. I want to generate synthesis audio with microcontroller.

Each pad has piezo electric sensor on its back. When its detect kick then the microcontroller will send sound to the audio peripherals. But with esp32 its not working properly. Sound quality is too bad and all sound hears similar. No cymbal, tom or other. All hears as the kick.
I am using esp32 s3 and MAX98357 I2S audio amplifier. I have tried from directly output through esp32 s3. But Esp32 s3 dont have any DAC.
I2S audio amplifier is not properly working.

Which microcontroller and audio peripheral willbe best for this project. This is my personal project, I want to achieve acoustic drum sound. and the sound will vary with the hit strength on the piezo electric sensor.

Please give me some suggestion.

For audio, I would suggest an analog devices part. AD also has software for it, special audio software.
