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.

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.
