    Custom Midi Controller

    I will probably purchase the Teensy 3.0 and use the CD4067BE chip. A fellow(fuzzy wobble) who built a custom MIDI controller that I am modeling mine after somewhat said to add because it "easily adds 16 analog input to your board. The four red wired linked between the Teensy++ and CD4067BE allow the Teensy++ to tell the CD4067BE which of the 16 pins it wants to read. The brown then sends the information for that analog input from the CD4067BE to the Teensy++. So if you require eight analog inputs or less, you will not need to add the CD4067BE to your PCB."

    For some reason I feel like this won't add any more inputs to my teensy 3.0, but if it does I would be glad to know if you could tell me. Also if I am using 16 rotary encoders, will I be able to include LED's? The kind of setup with my LED's are similar to the photo I will attach. I do not need to control the LED, I just want it to light up underneath the encoder like in the picture.Click image for larger version.

    Thank you very much on the input you have given/will give.Also I decided I will only have 8 encoders and 8 pots for variation, but I am still curious as to what adding the CD4067BE chip will do on the Teensy 3.0. There are very few who I can ask so I appreciate the help so if someone could recommend some LED's (and wether they should be horizontal or surface mount) to give me the kind of display in the pictures that would be great..
