Electronic musical instruments_Drum machine

[fendoap ,]

I'm fendoap.

I'm trying to make an electronic musical instrument using ESP32 and mozzi.

The device is equipped with OLED and some potentiometers and tact switches. 

I'm thinking of exchanging sketches to make various musical instruments.

I made a drum machine as a trial.

I also made a simple drone_synth

Here is some sketch:

 mozzi is very nice!  Thank you very much!

Hi how are you
I'm testing the skech you sent.
For some reason it does not compile.
I am using the ESP32 DEV Kit.
This is the error :

Several libraries were found for "MozziGuts.h"

On the other hand, I see this:
 u8g2.setFontMode (1);
u8g2.enableUTF8Print ();
u8g2.setFont (u8g2_font_b10_t_japanese1);

The source is in Japanese. This can be changed?


I send you greetings.

Martin

Hi!  I used the drum sample table so that part may be an error. Then I use the u8g2 library to draw the OLED so u8g2 library is needed.  ESP32 may not be supported depending on the version of mozzi.

Then u8g2.setFontMode (1);

u8g2.enableUTF8Print ();

u8g2.setFont (u8g2_font_b10_t_japanese1);

The part of can be changed. Because it was a code created while trying it, there are various unnecessary parts. Maybe it works without this part. Thanks!
