Fatar 61 key keybed controller question:

kyleivanblake · June 15, 2015, 2:16pm

I have a working Fatar 61 key keybed that I would like to build into a controller.

I was working with Arduino Teensy 3.1 and then I heard about MidiBox.

I am trying to figure out exactly what I need to purchase to put this together.

Can anyone point me towards a current thread that details what I will need?

I’m having a hard time understanding what is what with MidiBox as there are so many generations and versions of things, and so many different types of projects…

Thanks in advance, any help is appreciated!

Regards,

-Kyle

Something like this: http://ucapps.de/midibox_kb.html? Works with both LPC17 core or the new STM32F4. If you use NG firmware it will be the same.

You need a core (LPC17 or STM32F4) and a DIO_Matrix-Module. That’s it.

You even don’t need an adapter… I connected a bunch of 61key fatar keybeds directly to the DIO without any adapter.

That looks exactly like what I need!

Where can I buy the hardware? Is there a component list for the whole build?

I already converted the MicroMatch to a 2x8 in 1.27 pitch, I think it is the same connector the DIO_Matrix-Module takes from what I can tell…

The fact that DIO_Matrix can accept two keybeds excites me as I am considering using 2 of my 3 keybeds for a dual manual organ style setup. Does anyone know of a source for drawbars?

Which core do I choose?

Come on…

Please read through ucapps.de at first… it’s everything there (also component lists / orderlists)

You need a core… it doesn’t matter which one. The STM32F4 is newer and the “actual” one… so if you want to be sure to have the new firmwares running on the core, use the STM32F4. It’s cheaper and “faster” also.

You get the pcbs at Tims shop:

You need to solder them by yourself… there are no prebuild-pcbs available. If you are looking for that kind of stuff, take the doepfer-electronics.

What do you mean, “the “actual” one”?

“actual” = most recent

“actual” = most recent

Thanks

I build midi kb / midi ng with stm32f4 basecore + diomatrix and keybed pcb midibox_kb_scanmatrix_novel_type1 file: /// C: /Users/Administrator/Downloads/midibox_kb_scanmatrix_type1.pdf but the path from the socket pin 16 header is just c1, c # 1, d1, d # 1, e1, f1, f # 1, g1 mios bootloader with the latest firmware then input midi kb program through mios studio but in mios nonitor which read each one octave, what to do following my file include

Hello Tedy

I don’t have the answer to your specific question, BUT there is no need at this forum to post 4 time the same question in different sub section…

Best

I’d like to help but I really don’t understand what the problem is. What is connected to where? How many keys? Which keybed?

tedysuwarnady · December 9, 2017, 1:22pm

thanks for all the answers, sorry i already have stm32f4 + diomatrix running fine, then keybed 61 key pcb but to connect from stm32f4 module core ,how wiring 16 pin cable conctions? following schema i already make circuitboard is this correct and what should be in edit?

Like I wrote somewhere on the forum before: if you want to connect an 61key Fatar keybed to DIO matrix you do not (!) need any kind of adapter PCB. Just use two 16pin ribbon cables and twist them by 180 degrees.
