Hallo! Ik wil nog steeds een MidiBox maken om er gitaar effecten looper mee aan te sturen. Zie: http://www.midibox.org/dokuwiki/flo en Ontwerp is al een tijdje soort van af, alle onderdelen al een jaar in huis maar nog steeds niet gebouwd. (Wel ondertussen een paar gitaar buizen versterker verbouwd en diverse gitaar effect voetpedalen gebouwd.)

See:

There was a question on how to make a FX switcher with MidiBox: I redirected the TS to this thread. @RockRaver: "... when you say I only need one DOUT, you're saying i'll only need 1/4th of the DOUTx4 unit, correct? That would make sense as each 74HC595 can control 8 relays, correct?" Indeed when controlling 7 relays, you only need 1/4 of a DOUTx4 module. Actually, the CORE could control the 7 relays directly from one of its output headers so DOUT is not needed then, but this is not directly supported by the MIOS software so I decided to use a DOUT. See also: http://www.ucapps.de/mbhp_dout.html http://www.midibox.org/dokuwiki/flo#midibox

If you have no experience with MidiBox nor with PICs I suggest to make it a bit simpler like I minimized it in: "FX looper with MidiBox" http://www.midibox.org/dokuwiki/flo which is: - Use a commercially available MIDI pedal like Behringer FCB1010: http://www.midibox.org/dokuwiki/flo#external_controller_midi_floorboard - No matrix display only LED indicators that display which relay is enabled, the MIDI pedal will display which patch is selected: http://www.midibox.org/dokuwiki/flo#user_interfacekeep_it_simple - No storing of patches needed, this is done in the MIDI pedal: http://www.midibox.org/dokuwiki/flo#midi_implementation - Using MIDI controller change messages: http://www.midibox.org/dokuwiki/flo#midi_implementation - Only 7 relay loopers. One MIDI controller change message has 7 bits, each control the state of 1 FX looper relay. http://www.midibox.org/dokuwiki/flo#midi_implementation - 1 CORE and 1 DOUT needed. One DOUT can directly control 8 relays max. http://www.midibox.org/dokuwiki/flo#midibox. You can always extent later. Remember there's a lot to learn and do before even the simple one is done. About using relays see: http://www.midibox.org/dokuwiki/flo#using_dpdt_relays I wanted to use the ULN2803 Relay Driver Chip because its simple to use and cheap. You can use a transistor and do it yourself (like explained on Geofex: http://www.geofex.com/Article_Folders/rmtswtch/rmtsw.htm) but why do it the hard way? ;) You can use 5V or 12V types. Both will work as long if you have the power supply for it. I choose 5V types because the whole MidiBox runs on 5V. If you want to discuss that project please go to: Regards, flo

Hello! You're probably in the wrong topic but I leave that to the moderators. You could have a look at: "FX looper with MidiBox" http://www.midibox.org/dokuwiki/flo It's a design idea I did a while back but never did a complete build. I'm currently too busy with other projects (like tube guitar amps) to finish it. Would be great if somebody picked it up and continued it. :) Another idea would be: "The Pedal Box and Pedal Board Thread" Regards, flo

Don't worry about it! Sh*t happens... Keep up the good work!

The layout has developed had a problem with urls. ;) See: http://www.dokuwiki.org/syntax This went wrong: http://www.google.com This went right: [[http://www.google.com]] OR www.google.com So I changed all the links in my user page. Now the layout is good again. Still open: The Table Of Content is no longer automatically generated.

Does anybody know why the layout in my user page in the docuwiki is not nicely formatted anymore? http://www.midibox.org/dokuwiki/flo There used to be a content index on the right side with the "chapter" titles, this is gone. Also, many sentences are no longer nicely seperated by "chapter" or "paragraph" titles. It seems the "===" seperators are no longer interpreted nicely. I'm using Firefox 3.5.3 as browser. Btw: Nice new forum "look". I like it. Regards, Floris

Ah, sorry to repeat a bug report. Should have searched for this one first... :-[

After I save an edit in my user page in the MidiBox DocuWiki I get a white page that states at the top: Any idea why that is? The edit seems to be saved when I return to my user page. Regards, Floris

Thanks for handling it!

Dear all, I'm running FireFox 3.5.1 on Windows XP. When I go to http://www.midibox.org/dokuwiki/ or http://www.midibox.org/dokuwiki/flo I get a yellow alert bar at the top of the browser page stating: It has some links that I put here: http://bugs.splitbrain.org/index.php?do=details&task_id=1700 http://www.splitbrain.org/go/dokuwiki http://www.dokuwiki.org/update_check It seems to be a security warning about some DocuWiki setting. I did a forum search but could not find a post about it. I don't know who handles the MidiBox DocuWiki so I thought to post this here. Regards, Floris

2 black PCBs arrived in the Netherlands (almost around the corner). Thanks for the great service! :)

I can imagine the amount of work and time this takes must be huge! Impressive that you manage to get it done because I know the ever-growing ToDo list syndrome as well as trying to have a "normal" life next to: a job, making music, playing guitar, having a electronics addiction... ;) I did not mean to push or anything, I was just curious. And indeed try to have some fun while doing it! :D

hmmm it's kinda quiet here... Any progress on the design perhaps?
