# MIDI channel select
If you have a rotary encoder and OLED installed, you can easily change the MIDI channel for the board.
By rotating the encoder, you can change the channel from 0-16, or make the board listen on ALL channels.
After setting the MIDI channel, and a save delay of 2 seconds by default (this can be changed by modifying the `saveDelay` variable in the firmware), the channel will be saved to the Arduino's internal EEPROM.
This will be indicated by the ![ROM](https://github.com/sgilissen/purrChestrion/blob/main/purrChestrion-arduino/gfx_src/savetorom.bmp?raw=true) indicator in the top-right of the OLED.
The indicator will disappear after 3 seconds.
