So basically bro, ang imo need kay interface between your MIDI and DAW; am i right?
Nya ang iya main functions kay to detect events from the inputs on your MIDI such as knobs (pots), buttons (switches), faders (pots). etc.?
Naa koy gi DIY 2 years ago na almost the same ang concept. Basin makatabang ni nimo. Akong gi-customized ang akong rig before, gibutangan nako ug old school LED bargraph display linked to Windows Media Player thru a GUI (bargraph controller). PIC akong gigamit ani niya sa una pero akong giilisan ug Arduino (sacrifice lang nako gamay ang resolution sa ADC). Bag-o ra ko nag-update sa bargraph controller (c#) ani (2 weeks ago lang) kay nagkabuang ang cross threading pag-update nako to Windows 10.

Instead of MIDI, SW-based bargraph controller (slide bar instead of slide pot; radio buttons instead of actual mechanical switches) ug WMP (sound level/volume detection) ang akoa input; nya instead of DAW, LED bargraph display akong target. Atong interface, the same, microcontroller.
You just need basics of these: C++, C#.NET (or any framework which supports serial port/com), a bit of USB/Serial COM knowledge, how POT works and Analog to Digital Conversion.
Let me know if the concept is close/useful to what you are trying to achieve.
