A Capacitive Sensor Array as Music Keyboard

capacitive music keyboard
	Audio DSP	This project shows my recent music keyboard using capacitive sensor pads: PCB Hardware EAGLE Design Top and Bottom of the PCB design Each pad is touched from the component side (red) receiving two specially built signal patterns from the bottom side (blue). The amount of mixture in the receiving signal determines the detailed position of the finger at a normalised key position and thus the offset from the middle. This information is finally taken into the vibrato channel of the MIDI stream. FPGA Hardware Spartan 3E - System Xilinx Spartan 3E 500 - KIT Former Version
