I'm looking to build this project using only the STM32F4, MIDI IO and AOUT NG (possibly the SCS too). Since it's no longer active, and no download/config info on the main page (http://www.ucapps.de/midibox_cv_v2.html), would it be a better to build the V1 instead of the V2 as there is limited information on the V2 and I only need it for the function of MIDI to CV conversion? Not made a MIDIbox before but from looking around this seems like a good first step as I am trying to learn from scratch the skills necessary to build MIDI controlled acoustic instruments.
