A built-in backing band in a solitary pedal, the TRIO+ from DigiTech allows you to store five individual song parts, play them back in sequence, and tailor them on the fly to your performance purposes. Also, the pedal features a teachable rhythm section which can follow the chords you're playing and intelligently generate bass and drum sections in one of twelve genres, including Rock, Blues, R&B, and more.
Furthermore, within each genre are twelve individual and selectable styles, making the possibilities for variations quite sizable. Once taught and stylized, this "backing band" can be blended into the mix to taste via on-board knobs. Or you can opt to use the pedal as a traditional looper—only with five individual loops to switch through instead of the standard one. Either way, you can store up to 12 songs on the included microSD card, preserving the ability to adjust the tempo and dynamics of each song all the while.
Connection points also abound. For instance, you can route your signal to a mixer, an amplifier, a pair of headphones, or all three at once. You can connect via USB to a computer in order to manage your song library or update firmware. Complementing the unit's built-in loop and band switches, you can route an external footswitch into the pedal, and lastly, an included effects loop allows you to include your entire pedal rig in the TRIO+'s chain, should you want to.
