I have just uploaded a Youtube video of my latest Edrumulus prototype (Prototype 3 (HD-1)) in action. |

Yes, that looks good. I'm still with breadboards, but they appear to be stable for a long while now... (Teensy and more breadboards are inside that plastic box. The jumper cables at the top are soldered to standard stereo jack cables. Their counterparts go inside the box. The white USB cable at the left goes from the Teensy to the PC.) |

Same to you!
I got me a Teensy 4.1 and i 'd like specific info on what needs to be ''changed'' if/or needed in the latest main code , as to try a new implementation instead my {almost perfectly working } Esp32 built .
My main 'concern ' is the changes needed to have the Teensy working with 9 pads like my Esp 32 does .
I see on the hardware .cpp the following settings but these seem to be for 8 pads as is :
#ifdef TEENSYDUINO // e,t,c code
static int analog_pins1[] = { A10, A11, A12, A13, A1, A6, A4, A5 };
static int analog_pins_rimshot1[] = { A9, -1, A0, -1, A3, A8, A2, A7 };
Do i simply have to 'add' one more Teensy pin in here arbitrarily and maybe un -comment some lines on the main ino ?
Yes, exactly.
You also need to modify the edrumulus_gui.py to be able to modify the settings (`pad_names` array IIRC).
In my tests the Teensy 4.1 CPU maxed out at 14 used analog outputs.

Did you build your own Edrumulus e-drum module? What are your experiences with Edrumulus? Please share it to the community!
Please post your report+pictures in this thread. Thanks :-)
