SamplerINO utilizes an ATmega32U4 microcontroller and two CAP1188 8-channel capacitive touch sensor modules to assemble a USB MIDI controller featuring 16 touch-sensitive pads. The prototype circuit board is housed inside a custom-designed 3D printed enclosure, which facilitates the installation of the pads, as well as an LED indicator and a power switch. You can watch a video demonstration of this hardware MIDI controller and its dedicated software sampler at the following link.
The code in this repository is organized into several directories, with the source (.cpp) files, header (.h) files, and external libraries of the controller located in the src, include, and lib directories, respectively. The Max patch implementing the user interface of the accompanying sampler, along with a collection of drum samples gathered from various royalty-free web sources, are contained in the max directory. Lastly, the 3D model (.stl) files are located in the 3d directory, while the img directory contains all images displayed in the present documentation.
This project was developed using Max 8.1.11 and Visual Studio Code on Windows 10, with the PlatformIO extension employed to upload the code to the ATmega32U4 microcontroller embedded in an Arduino-compatible Pro Micro board. The controller pads were made by cutting 4×4cm pieces from a 0.5mm thick copper sheet, while the enclosure screw holes were designed for M2 threaded heat inserts. Lastly, a common anode RGB LED was used for the LED indicator.
