Hello community, This will be my first midi-project, and would like it if some people can guide me around a little. I'am a student on the HKU(arts academy Utrecht, the netherlands) for a next project i would like to build a midi-box for controlling a VisualArtists program written in MAX/MSP. The midi-box will allow for users(other than the vj) to make small changes to the visuals, live! The overall design of the box will look as followed: 3 rotary encoders that will control a value from 0-127 or maybe limeted to only 0-100 3 led-displays for the user to see what the value of each encoder is. See drawing: I'have snooped around on the website and the rest of what google offers me. And made a preliminairy design of what i think should be the hardware of the box. I understand that once the hardware is finished, the race is not over and i have to start looking at MIOS etc. But thats for later. In short the device should give: - three times a value of 0-127 to the software - The actual value should be displayed for the user - connecting via usb to mac As far as i can gather i need a core module, 2x a doutx4, a dinx4, rotary encoders and 7-digit led displays. I made up a electrical diagram. ps the midi to usb is an external I'am completly new with this kind of electronics so i was hoping someone could give me some feedback on the design i made and/or if im going the right path. Is it ordering time already? hope to hear from someone soon Thanx you very much Ivo
