hey wilba, ive considered that.. but the main problem is that the battery compartment has room for only 3 batteries :S

im going to use a stabilized PSU.. pretty expensive one at that.. supplies perfect current..

NLX: thats what i was thinking of aswell.. also it would help me to prevent my synth from falling of its respective stand..

that settles it.. power over midi is entirely possible!

we can always try it to see if it works..

power cables are usually AC.. AC changes direction.. DC does not.. therefore i figure that DC would pose less of a problem for data then AC does.. well.. im guessing that..

NLX: that would be a good idea, however its not the plug that im worried about.. its the psu itself. it not permanently connected to the wires.. so i could swap polarity there.. and then the plug itself would be backwards.. i dont mind that it eats .7V hmm.. maybe ill just leave the power stuff on there.. nothing could go wrong in that case.. well maybe it wont fit.. but thats a risk im willing to take :D therezin: try ebay.. or marktplaats.. ive seen 2 of these same guitars on marktplaats (the dutch ebay) and indeed its crazy :D

hmm.. id like to leave the rectifier.. so i dont have to worry about polarity.. would that be possible?

very cewl.. first ill have to trick out the guitar with the modules.. and then try to code something :S edit: i wonder if i can remove the huge capacitor from the core board if im gonna use a stabilized PSU? wanna make the core as low profile as i can get.. ive got limited space in there..

i dont quite follow you there stryd_one.. to my limited knowledge.. on the DIN PCB all the +5 lines are connected and it doesnt matter which one you pic.. then i would be stuck with only 3 inputs... hold on... are you saying i can use the dout as supply lines?? thats interesting..that would mean that i can scan in sections.. yeah.. does anyone know if this is possible in TK'z design?

*note* make the preset menu buttons double click for prevention of accidental press

hi guys, again with another MB project this time the midibox axe. dont worry the other projects wont be forgotten. however the other project (MB chaos specificly) will be needing me to know more about programming mios then i do now, so i decided to take on a lighter task first.. the midibox axe: im going to build a midicontroller out of this.. the "piano" keys will control the base note, and the red buttons on the neck will be the interval from that ground note. the yellow buttons wil transpose the piano notes temporarily(keep pressed to transpose) to a half octave up, a whole, 1 1/2 octave and 2. the blue triangular arrowlike buttons will be used to switch synth presets allthough there are four and only 2 will be used for that.. dont yet know what the other pair will do. and finally the green.. the biggest will be modded to be a pot meter for modulating pitch, cutoff, resonance etc. and the other 2 will be used to switch between such selections. the 6 neck buttons have leds under them.. which will be used.. for example to see if you have one of the transpose button pressed or maybe to show what note you are pressing on the "piano" part.. or amount of modulation. maybe even all of that.. there will not be a LCD. as this is a lowbudget project.. let me rephrase that.. its a no budget project. ive already hit a few snags.. first off the 6 button parts (the Piano and the red neck buttons) have peculiar connections.. for example the six red neck buttons dont share one common +5 wire.. instead there are 2 "in" wires and 3 "out" wait ill draw you a picture can this be incorporated into midibox as is or do i need to modify it? i really dont wanna modify this.. as playing with tact switches is a bitch.. and tracing a new pcb wont be possible soon.. and soldering on traces themselves? not a very easy job! even more difficult is that the leds have a connection in this aswell.. however that i solvable. secondly, im affraid i dont have enough space to place the core the din and the dout in there.. but i'll think of a way when the time comes.. unmultiplexed AIN.. possible, right? (havent searched the forum for that yet) i only need one ain for the potmeter with greets, wisefire

the only modification you would have to make is the transformer i guess.. the transformer or ringkern this design uses is for 230V

NO, no gun.. soldering guns are not usefull.. and 30 watts is too much aswell in my opinion 15 watts is more than enough for pcb soldering. and my tip for buying the module kits, get them at smash.. they look nicer and are more suitable for beginners..(allthough i dont know if that is true for the most recent boards)

i actually understand whats going on here. newstephane the link you gave us was a SOFTWARE implemenation, that means its a program which runs on an ordinary PC and EMULATES the OPL chip. its not for programming it.. also if you WANT to UNDERSTAND midibox.. you should read!!!! READ and READ.. its all here.. it explains all.. well most of it.. still your post is unjustified and i feel you are not treating us with the respect we have given you!

and its an easy, cheap and good alternative to his power supply! well actually his power supply is an alternative to this.. but who is keeping score? im not :P

its on my to do list..

you could also use the original PSU from the C64.. and if you optimize it (search for optimized psu) you could get some very good results out of that..

first i want to applaud sappoman.. thats the most transparent explanation ive seen.. secondly he did ask on the french forum.. guess it isnt that populated.. thirdly ehm.. there is no third..

yeah great stuff.. and the only ingredients are a grape.. a knife(to cut the grape) and a microwave.. or as we dutch say a magnetron..

i did that to my lcd ribboncable.. works great..

that horn probably only needed 12V.. or maybe it was only a speaker.. and then you could have hooked it to an amplifier :P and btw its VERY dangerous to mess with high voltages like 110V you could have been killed..

hey alex, ik kan de resterende 5 euro wel opvullen denk ik.. ik heb nu 3 euro aan condensators en weerstanden..

midibox should have a stand there :P

nej, de voti encoders wil ik niet ruilen voor alps encoders.. ik heb nix aan maar 2 alps encoders.. die bourns encoders zijn detented. oderlist gemaakt voor reichelt en mouser, mouser is niet heel erg nuttig aangezien ik ze per 10 moet bestellen.. bovendien is het via mouser helemaal een gedoe, aangezien ze een aantal dingen niet in stock hebben.. reichelt heeft alles wat ik wil. behalve een shipment policy voor onder 150 euro.. :P smash zijn website is uit de lucht dus ik kan niet een gedetailleerde orderlijst maken :S wat betreft de female sils, ik koop altijd de grootste en snij eraf wat ik niet nodig heb. en ik heb ook nog wat dils nodig voor onder andere de nieuwe boards en de lcd..
