Line 6 floorboard with the kemper ?

This won't work!
But User "mDan" developed something like a translator, just write him a PM.

Id like to know more about mDan's "Translator board" for the Line6 Floorboard too!

PM already sent to mDan

Hi, did you receive some informations ??

Still Nothing, and no word from mDan.

I would surely like to know about mDan's thoughts on this.

A google search reveals a few who have used a gutted Line 6 Floorboard as a foundation for an Arduino based MIDi foot controller.

Or this third party DIY MIDI board
http://wiblocks.luciani.org/NB1/NB1A-MIDI-index.html

You mean a modification of the Floorboard ?

Correct!

Break out your soldering iron and add one of these internal DIY MIDI control boards

Thx, tell me if you do something like that, it can interest me.

I've just take look to the links but i'm not so good in english and head will blow up !!

I did a search on all of mDan's old posts and came up with this:

"Converter to use Line6 FBV Boards with the KPA"

There is progress to report
In terms of hardware I've decided to make the whole based on the Arduino is simply cheaper if not tinkering you can customize the home in large numbers I will make the source code available once the project is completed.
I've chosen a way based on the Arduino Mega AT 1280 - depending on equipment costs 30-60 € and can do everything - he is only required for the FBV, as this will require several UART interfaces. For the simple display or the Midi Board also extends a small Arduino that you get from 15 €.

Since MIDI programming ansich no big thing is I want to first make it to the decryption protocol of the FBV.

The FBV pin assignment is as follows:
1: Ground
2: VCC
3: TX
4:
5: VCC
6: TX +
7:
8: RX +

I refer to the transmission line of FBV with a storage oscilloscope "tapped" and get the following results:

Bank Down button is pressed:

Bank Up button is pressed:

For a better view each marked a byte:

You can see:
- Baud rate is 31250 bit / s (like MIDI)
- Be Sent 5 bytes (each with 1 start bit, 1 stop bit and 8 data bits)
- 5V logic
- Synchronization frame (or whatever you call it -> 0xF0)

It is important to note that I am oscilloscope accidentally TX + TX-measured rather have - LOW level HIGH level corresponds to 5 V and corresponds to 0V.

I then wrote a little program that I wrote the 5 bytes sent to a display, it came out that the FBV also sends back 5 bytes (with a 0 at the end, instead of one) when you release the button again.

It will look like eg. like this:

Code:

On Off switch

Bank Down F0 F0 03 81 00 01 03 81 00 00

I can now all editions of the FBV (buttons, pedals) to evaluate and convert it into MIDI - right now I'm trying to figure out how I can appeal to the LEDs and the display. So if anyone has an idea: Let's have it

I've got the controller EVM from mDan, but am using a different controller right now. Still have one of the boards and all the major ICs that are soldered onto it. So if anybody is interested contact me via PM.

Hey rob,

I'll Probabily take off you, is it just a matter of connecting a shortboard too it or does it need 'work' putting into it?

Cheers

The whole thing is converting the proprietary Line6 protocol into a standard MIDI one. For this task you need a micro controller with some software to interface between the Line6 and Midi. As a micro controller an Arduino 1280 EVM is used (about 25 EUR).

The controller board from mDan is interfacing between the Line6 Shortboard, MIDI and the Arduino micro controller (opto-coupler, signal levels etc.). Also the software for the micro controller is from mDan.

So the set up is as follows (ignore dots):

Line 6 Shortboard ---(RJ45)---> mDan's Interface Board ---(MIDI)---> Kemper KPA
.................................................................... /\ ....................................................................
.................................................................... ....................................................................
.................................................................... \/ ....................................................................
......................................................Arduino 1280 uC EVM

So you need:
- Shortboard
- mDan's Interface Board
- Arduino 1280 uC
- power supply, 9V
- RJ45 and MIDI cable
- some kind of housing or case to put in the uC and the interface board.

Alternatively, you can directly include the Arduino and the Interface Board into the Shortboard.

So I think some basic handicraft skills in electronics are necessary to fulfill the job, but then you will be rewarded with an inexpensive controller with lot's of functionality and nice stomp pushbuttons.

mmm unfortunately I don't possess them skills.

Has anyone on here actually successfully got this fully working? Do all the functions work wah etc?

Cheers

Actually, I think there are a few people on the board running this at the moment. The software for the uC has previously been used and tested with the Axe Fx (you could use the Line6 Shortboard also to control the AxeFx with this interface).

I was also part of this project and I wrote most of the source code that runs on the micro controller. I continued the developement and made it compatible with the KPA. Here's a short clip explaining the development (The explanations are written in German but I hope the rest of the video is self-explaining).

https://docs.google.com/open?i…jB3SVpRU0ttMGhEdDg5dkxrZw

Please be aware that this is currently a so called offline solution. Every change in the KPA needs a new synchronization with the micro controller.

If you'd like to get access to the source code please send me a message. But I am not able to support you in technical questions regarding the hardware-interface - maybe mDan can post the schematics for the hardware here. I will not build more hardware-interfaces and/or housings.Please don't hesitate to send me questions regarding the source code but don't send requests regarding the hardware. Thanks.

Hoschi,

Yes I'm interested in obtaining the source code - but sadly it appears you have not enabled your Kemper Forum private message system - so I can not send you a request.

Please send me a PM with more details.

Hi,
I'm also interested in this project. I'm an electronic engineer so I might be able to do everything myself, please send me the code for running the microcontroller.

Thank you very much in advance.

PS do you anything about the project by Vlotech? http://www.vlotech.nl/?q=node/252

I also have the line 6 floorboard (not the FBV), if someone is running it with kemper please tell us how, thx !

Would be awesome!
