Hi everybody, my name is Florian (aka Thoskan) and I live near Toulouse in France.
First of all, Thanks to all of you for sharing all this documentation about the project MIDIBOX KB.
Initially I wanted to buy the controller LMK2+ alone without the keyboard, but Doepfer wanted to sell me 500 euros. So I refuse and opt for the MIDIBOX project, more interesting, configurable and also much cheaper.
My project is to midify a keyboard Fatar TP/40L, and I chose to use MIDIBOX KB, with the CORE_STM32F4 and DIO_MATRIX.
I bought the 2 PCBs from https://modularaddict.com and I also printed the FantomXR PCB (Fatar keybed adapter http://www.midibox.org/dokuwiki/doku.php?id=fantomxr) at OSHpark. Thank you FantomXR for this missing piece to my project.
For the moment, i just want to connect the keyboard (2 micromatch of 20 pins ), a sustain pedal and 2 yamaha FC7 pedals to control volume and fx.
I bought all the components from https://www.reichelt.de/ from the orderlist. Moreover, the STM32F407G-DISC1 is available here: https://www.reichelt.de/?ACTION=3;ARTICLE=219363;SEARCH=STM32F407G-DISC1. It is a little more expensive than at Mouser but the shipping costs are lower (20 euros at mouser vs 5 euros at reichelt).
I look forward to receive all these components and I hope that i will solder very soon.
I will share every step of the construction, that's why I created this topic.
I hope I will not have too many questions.
Thank you Thorsten for this great project and for your generosity.
