Chorda allows you to play any major or minor scale. You can change between the two using the 8 Pad (KEY).
Press the A button and then press Pad 8. While holding the A button, you’ll see the bridge triggers light up red and green, which function as up/down selectors. In this case, Select one of both the Green and Red triggers to change from major to minor (and minor to major).
You can also do this using the Artiphon Connect app. If you’d like to change the key on your Chorda, check out this video.
