hello, I am very new to arduino but I wanted to make my own project .. especially for Arduino Drum.
I have 6 months working on this project.. I think all run normally, but I find problem of the hi-hat controller when I uses sensors tcrt5000..
I could not find a solution in another forum and I would like to ask here ..
what I want is Arduino sends CC (Control Change) to the Drum Software (addictive drum 2) using TCRT5000 ..
I give a schematic and sketch that I use ..

int MaxPlayTime[16] = {35,25,25,25,25,25,25,25,25,40,25,40,25,25,25,25};

As you can see in the schematic, HCC (hihat control change) is P4 connect to the CD4051 when seen in Sketch .. pins are connected with HCC is no 99..
I'm sorry if my english is very bad ..
