Soundguy tool helps you keep track of the inputs on a 24 channel headbox on a phone. Please feel free to make suggestions for improvements! Keep in mind that this is my first Android project and it might take me a while to implement stuff. Happy gigs!
Use: Tapping the instrument buttons on the bottom will fill in the channels starting at channel one. Tapping on a channel will clear that channel. Tapping instrument buttons will fill that channel, filling in as before.
