My DTo arrived today 
After the first power-up, no sound came out. I had to do a factory reset to make it work. I find the sequencer quite awkward for melodies and chords, especially if you want to enter trigs in grid recording with a MIDI keyboard. However, the planless editing of FM combined with subtractive synthesis makes a lot of fun. While editing, the DTo crashes a few times. After turning it off and on, it worked again. The software still seems to have some bugs. BTW, the DTo’s display is noticeable better than the display in the DT: No lines, no shadows … simply amazing.
