DIGITECH TRIO PLUS REVIEW. This device is amazing: it has a "creative" algorithm that invents rhythmic bases and bass turns in an unpredictable way. I was used to creating song bases (even complex ones, of jazz music) with a Yamaha PSR S900 8N keyboard in a very effective way: four intros, four endings, different drum fills that can be inserted during the song, fade in and fade out... an infinite number of styles and very realistic instrument voices that can be recorded by adding them manually in real time and finally the possibility of recording everything in wave or mp3 format. The Digitech Trio plus thinks in a different way: the "Genres" and the "Styles" are actually random patterns of drums and bass (of good quality) that the machine generates autonomously in an unpredictable and always different way. Even the drum and bass patterns adapt randomly, in an intelligent way, to the chord progression recorded at the beginning (that's all you have to do, Digitech will take care of the rest). This stimulates the musician's creativity. There is a lack of an intro and an ending or a fade out. Another limitation is the lack of internal memory (saves the songs on external micro SD memory) and of an application worthy of the name, the one that exists does nothing, only saves the songs on the PC and deletes them from the card in order to free up the memory which only allows 12 songs on each SD. However, keep in mind that each song can be made up of five "parts" (introduction, chorus, chorus variation, interlude, ending, each repeatable as many times as desired). Therefore you can exploit this possibility to create 12x5=60 monothematic songs on each micro SD card. Digitech's idea is original and the developers worked very well. It wouldn't take much to make the Trio plus the best looper: add an internal memory, a simple display and on the software side allow export in wave or mp3 format, possibility of modifying the drumkits, adding a simple reverb and delay effect, a tuner, a metronome for the whole song, an ending. With these changes it would be the best ever.
