Reply to Tannin DIY MIDI Controller

I'm well aware that I haven't updated this thread for a long time - it's for a reason. That project is simply too complex and too expensive for me to finish it in some reasonable time. Project is still open and up on GitHub, if anyone wants to build it. So long story short - I've started doing something much more simpler - Tannin. It's a project I actually managed to finish (well almost, I still need a box) in about 3 weeks from scratch. I do have 3,5 years of experience with OpenDeck tho. So here are the specs of Tannin:

4x4 matrix of tactile buttons
3 additional metal buttons
4 LEDs with metal holders
16 pots
Driven by Arduino Nano microcontroller

And here's a short video of it in action (it's pretty hard filming and showing off features )

Features are mostly the same as OpenDeck:

Each potentiometer sends additional 6 MIDI Note On/Off events depending on its position
Each button sends another MIDI note after 1 second on another MIDI channel
MIDI In Support (Traktor can control LEDs)
Standard MIDI Note On/Off support

Looking forward hearing opinions.
