Fatar TP/40L Midification

15 posts in this topic

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. :rolleyes:

Thank you Thorsten for this great project and for your generosity.

For you to know that if your order amount is more than 70€, shipping is free at Mouser, then it's some time better to wait and group your order.

Best regards

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.

@Thoskan

Hello Florian,

I have a Studiologic SL880 (Fatar action) and want to replace the electronic.

Now I evaluate my two options. Making it a Doepfer PK88 (only Midi channel 1, but support of all three pedals) for 250EUR.

Or building a MidiBox. Have you finished your project already and do you have at least a volume and sustain pedal working?

Do you know the total costs?

 

thx,

Markus

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

Where are you located?

I have made a core, that has everything on board. Just connect the keybed and that’s it. I think I still have some units left. 

Let me know!

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 !!

Yes it's an unconventional keyboard :rolleyes:

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 !! 

FantomXRDo you have pictures of your old MIDIBOX project ?

Great i am in for it. I love those Keybeds.  I can solder too but you seem to be the more experienced guy. i need at least 2.  both Motherboard died recently i have one working as lower manual to a Hammond xk3 organ. Lets do it like this.  solder one for me the other one i solder myself i like to learn something. maybe i am going to build a pedalboard for my organ. do i have to change something on the ribbon cables to be able to attach the keybed? and what is the price you are asking?
