Hello, I think the idea to recreate the possibilities of an analog synthesizer 70/80 years in a game console is just great. The realization approaches perfection. The reasons for the difference (because it will be briefer to quote the imperfections than the reverse) are: . Not opening the software that forbids him today to be controlled by MIDI controller via a wireless link from a PC. . The limit of 16 patterns by even these latter session has 100 steps to chain patterns one after the other. . Failure to start / stop the sequencer instrument. . The failure to transpose a set of notes on the construction of patterns screen. but there is a work around. Otherwise, I hope that a new version will come (maybe if she called DS20?)
