Did you know that there are “hidden” arpeggios in Program and Combi modes the KORG’s Triton Le? When selecting some sounds, the ARP ON/OFF key is unlit, and with other sounds, the key automatically lights, and the arpeggio pattern(s) trigger as soon as you play the keyboard. Normally, you would think that if the light is off that there aren’t any arpeggios available, but there are patterns pre-assigned to EVERY Program and Combination in the TRITON Le. So, how do you access the “hidden” ones? Simply press to turn the ARP key ON (lit), and then play the keyboard to trigger the assigned patterns!
