Midi "hardware design" newbie question..

MIDIbox HUIs

Hi there,

I’m new here.

I really want to make myself a midi switcher for my guitar rack.. And a foot controller..

Can somebody tell me something about this? And help me?

EDIT: i have made a remote loop system, this system i can use in the rack part of the system.. So what i need is a midi foot controller and a midi reciever in the rack which controls the cmos circuit..

Thanks,

RB

Hi mate,

Welcome :slight_smile:

You should search the forum, this same question was asked just days ago… There are also notes on ucapps.de

Cheers

Thanks, Todd..

I started searching the forum yesterday but didn’t  “finish”:smiley:

I’ll look more today.. Thanks,

Robin

Good luck mate… Get yourself a nice big bottle of water, some food, smokes, maybe a donkey or camel to carry all the supplies… And don’t forget some cash to pay the sherpas… It’s gonna take you a while  ;D

I’ll do so..  ;D ;D

Anyone who can give me any links or someone can explain something about the Midi Itself?

Like:

Programming?

And what do i need to program the EEproms?

Any big tips??

Thanks..

Robin

Run a google search for PIC ASM Programming, for MIDI Technical Fanatic’s Brainwashing Center, and search around on here and www.ucapps.de for info about programming eeproms. That should help.

Ok,

Look at this-

Can you tell me something about it?

Is O/P 0 - 7 "control outputs? to an op amp?

And what the heck is midi channel?

Thanks for your help..

midi has 16 different channels

so with that dip switch i gues you choos which one you send or listen on

O/P is just an output 

what you connect to it is up to you

it could be just an LED or an driver and an relay

I see “Image Hosted by Tripod” .gif logo. :wink:

Tripod uses referrer logging to prevent off-site image linking. Better go to the page, where you can find the picture, “Circuit Schematics”: http://tomscarff.tripod.com/prg_chx8/program_change.htm

Ok, then i start to understand this (i think)

What about the programming of that chip??

What can i tell the chip to do"?? And how can i integrate it with other switchers foot-controllers(skrydstrup, axess, or CAE)

Thanks,

Robin

What’ output RA0/AN ouputs??

And what’s the SW "output’s or something?

This is not a Midibox subject.

Ask all these questions from Tom. (the guy selling those (non Midibox) boards)

In the MIDIbox context (and maybe further help in this forum), try this: http://69.56.171.55/~midibox/forum/index.php?topic=4313.0 (and maybe http://www.ucapps.de/floorboard.html)

Bye, Moebius

p.s.  RA0/AN outputs do nothing - “SW’s” are used to send midi program send messages. And the programming of the chip - you have to order one from Tom Scarff.. this has nothing to do with midibox.

Tom’s stopped selling boards & PICs now, but he’s kindly left all you need to roll your own. You’ll have to download the code & burn your own PICs & make your own PCBs too.

I am looking into building a MIDI switcher for my guitar rack as well.  Check this guys site:  http://www.jimkim.de/html/guitar01_01.htm

He is very helpful, too, if you ask him questions.  I’ll let you know if I get anywhere with mine.  I’m about to move, so it’ll be a month or two before I am able to begin, but I need one for my rig as well.  As far as I can tell, it would only cost about $50 us to build one.  He provides the software.  I’m also considering building a footcontroller based on the MIDIbox concept.  :)
