drum pad, midi controller for Ableton live

[seayaker]

Can anyone tell me how to get Ableton live to recognize the teensly 3.6? I downloaded the Arduino and Teensyduino, have the 3.6 on a breadboard with a piezo connected to first analog + and ground Is there a some simple code I could download just to get it working and go from there? Any help is greatly appreciated.

What is the code used for this? https://www.youtube.com/watch?v=QpKEve9p7yw

In Arduino, first make sure you have the correct Teensy selected in Tools > Boards.

Then click File > Examples > Teensy > USB_MIDI > Buttons

Before you upload, you also need to click Tools > USB Type and change it to MIDI. By default Arduino+Teensyduino makes your Teensy become a serial device. This is the place where to tell it to turn your Teensy into a USB MIDI device.

Then click the Upload button.

A few seconds after Teensy starts running the Buttons example, you should see a new MIDI device. Open it with Ableton or whatever other software you like. Connect buttons to the first few pins, or just use a wire or paperclip to touch them to the GND pin to "press" the buttons. This example sends note on / off codes, but hopefully it's easy to understand and can give you a good starting point for more interesting work.

Thanks for responding, I got to the point where I can open it in Ableton and trigger notes by touching the wires. Now I need to trigger with a piezo and make it velocity sensitive. Anyone who has done this and can guide me I'd appreciate it.

I still can't get the piezo to trigger anything, for example note 36 which is the kick drum, is set up in my DAW tested with another midi device. I connect the Teensy 3.6 which triggered a note with the buttons sketch but cannot get it to work with any of the piezo drum sketches. I have a 1m ohm resistor connected across the piezo which puts out 1 volt max. still get nothing with any analog pins. I tried changing to serial+midi hoping to see it on the serial monitor it does not show, is there a way to see what is being triggered and map it to the right midi note?
