Yes it's an unconventional keyboard
I adapted the fatar to my needs and especially the size of the flight case !!
It also makes me piano parts (Keys, springs, ...) , and the keyboard goes into the trunk of my car ;) Also it's much ligther (27 Kg now Vs 37kg with the PC3X and case). My Back is so happy !!
FantomXR, Do you have pictures of your old MIDIBOX project ?

Hi eveyrbody, just for information, i published an github (https://github.com/OrangePeelFX/DIY-Keyboard-Fatar-TP40) with my notes on this project.
My fatar slept for a year, but I found the energy to finish this project.
Thx to FantomXR and Thorsten for your help and your sharing !!

Hi markus,
For this project, i used Midibox NG cause i can use the interpolation to compute the velocity. It works very well with my TP40/L.
if you choose MidiBox Project, You will pass many hours to study topics and documentations, but you will be very proud of you. I can affirm you that my keyboard works well and i can connect my sustain pedal. I study now the connection for expression pedal.
If you have time, i will write a tutorial for my project very soon
best regard

Hi everybody ! Bonjour à tous ^^
I received my electronic cards, and I sold everything. Everything worked perfectly right the first time, except that I had just reversed the cables that connected the TP40.
At first I installed the firmware MIDIBOX KB, but I really struggled to get something reliable in terms of velocity. While looking on the forum, I saw that other people used the MIDIBOX NG in order to be able to use velocity curves. (http://midibox.org/forums/topic/20344-speed-up-scanrate-of-ng-by-kicking-out-other-scanroutines/)
I will do the same, and try to find the right settings for me.
I still have to know how to connect my 2 sustain pedals and my 2 expression pedals. In fact I use mainstage with a left hand part (rhodes bass) and a right hand part for other sounds, and I would like to have two separate sustain pedals. I still have to find out how to do that. If you have ideas I'm interested.
Here are some pictures. -
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.

hi fantomxr and skunk.
As fantom said before, you can use KB software if you want a better scan rate.
But personally, I used the NG software because you can define a velocity curve, and I preferred in terms of feelings.
You can start with KG or NG, whatever and later just change the program. I did that and it was ok.
I made a github deposit after my first experience just to keep a written record because it's a lot of research work when we don't do electronics.
You can visit it : https://github.com/OrangePeelFX/keyboard-fatar-tp40
Good luck for your project.
