[Christian] wrote in to tell us about his third-generation Arduino MIDI sequencer (translated) called the AM808 VX3. He had already laid a strong base for the project in his previous versions. But the user interface was still frustrating at times and that’s where this version comes in. it features a nice clean dashboard like interface, but also includes a configurable virtual interface.
The obvious components seen above include the slider and potentiometer band, as well as the repository of buttons mounted below that. But in the center of the board is a touchpad which [Christian] pulled out of an old Laptop. It interfaces as a PS2 device which makes it pretty simple to use in conjunction with the Arduino. But that’s not the only touch-enabled input device. The rectangle to the right of the touch pad is an LCD screen with a touch overlay. As you can see (and hear) in the clip after the break, the touch screen made it possible for him to rework the controls until they became simple and intuitive.
