Giovanni,
The Midijay was designed with the accordion player in mind. It has most of the arranger features you currently use/have on your technics, but where it differenciates itself from other arrangers is in it's true NATURAL sounds and authentic styles. When you walk into a room and hear someone using a MIDJIAY, you say to yourself ... that band sounds great ... until ofcouse you take a closer peek. The Midijay also comes with Wave and MP3 playback manipulation (change of pitch, tempo, removeing Lead parts, sync to Midifiles, associate with text ..) etc and so much more.
Contact me if interested.
