Drum Pad

Drum Pad

The gen4 uLCD-70DT Drum Pad project is a virtual and complete drum set that are played using the touch functions. As the users press each drum instrument, the gen4 will command the SOMO-II to play each sample drum instrument.

The bass drum is automatically played in a loop and can be set in different tempo or beat signatures.

The snare drum sound sample is on medium tension, the base drum sound sample is muffled with a pillow.

The project is best using a gen4-uLCD-70DT because of the large screen area to play and place the buttons, it also uses the super-fast DIABLO16 processor that makes the drum set receptive to simple or soft touches.

Implementation

Step 1: Build

If you are using gen4-PA board, connect the display to the PC like the image below.

Step 2: Program

Download the project file here.

You can download Workshop 4 IDE and the complete code for this project from our website. Open the project using Workshop 4. This project uses the Visi Environment. You can modify the properties of each widget.

Step 3: Compile

Click on the “Compile” button.

Note: This step could be skipped. However, compiling is essential for debugging purposes.

Step 4: Comp n' Load
