Nard Drum Midi Controller - Making Multipad Drum Midi Controller with Arduino Pro Micro

Version 1.0

Version 1.2

What you'll need to make :

• Diy Multipad Case from 9mm Plywood and Pine wood
• 10mm Rubber sheet
• 20mm hard foam sheet
• Arduino Pro Micro
• Multiplexer cd74hc4067
• 11x Piezo
• 15x Resistor 1M Ohm
• 15x Diode Zener 5.1v 1N4733A *revision 1.2
• Must use shielded cable (and twisted pair if you can) *revision 1.2
• 16x 6 Pin Female 1/4" Inch 6.35mm Stereo Jack Socket (i will give the picture on bottom, use this spesific socket) *revision 1.2

Feature of Nard Drum Midi Controller :

• 11 Pad
• 1 Input Hihat Pedal (For now i use Digital - Momentary Button for 3 Midi Note : Close / Open / Pedal)
• 4 Input to Expand the kit (Kick, Cymbal, etc)
• 11 Output to Drum Module (Will bypass all signal to Arduino) *revision 1.2
• Open Source Code. You can change and improve the coding. Github Link
• You can use the Code for building Full Drum Kit Controller.
• Flexible, You can changes the Value in the Code :
• For All Piezzo input :
• Active : False/True
• Midi Note (0-127)
• Min Threshold (0-1024)
• Max Threshold (0-1024)
• Min Velocity (0-127)
• Max Velocity (0-127)
• Scan Time (0-1024)
• Masking Time (0-1024)
• For Hihat Pedal :
• Midi Note Close (0-127)
• Midi Note Pedal (0-127)
• You can use Arduino Pro Micro (Recomended) or Arduino Leonardo
• You can use this Multipad Drum Midi Controller on PC/Computer or Android Phone with app FluidSynth MIDI (Use channel 10) *revision 1.2
• *I still using Bahasa Indonesia on Code, Just use google translate. 

To do :

• Adding LCD Display module
• Adding 2 Rotary Encoder for Menu Navigation
• Adding Menu on coding. so you can change Value without tinkering with the IDE
• Adding  Optical Hi-hat Controller with TCRT5000 Module like this one

I am still progressing in making this project. Currently I am working on assembling the electronics. If this project is finished, I will upload it to youtube.
