This is Mouser 's mistake it's a 40x4 LCD look at datasheet
-
I want to power my SeqV4 and AOUT module with it. But the AOUT module requires +/-12 V. Should I use 7812/7912 rectifiers to get +/-12V or can I directly power the AOUT module with +/-15V?
both solution are ok

beau projet en effet, :thumbsup:
Avec quel soft as tu créé le design?
-
T'es sûr? :smile:
Parce qu'il y a tout de même un détail qui m'inquiète, c'est que par exemple, le mode "User" totalise à lui seul la bagatelle de 1378 paramètres!
80 potars x 4 layers x 2 (Shift) = 640
80 boutons x 4 layers x 2 (Shift) = 640
22 faders x 2 (Shift) =44
16 boutons x 2 (Shift) = 32
8 encodeurs x 2 (Shift) = 16
3 boutons x 2 (Shift) = 6
640+640+40+32+16+6 = 1378!
En fait ce ne sont pas 1378 parametres car a chaque changement de layer tu enregistre tous les parametre precedent dans l'eeprom ce qui fait que le programme ne gere que les parametre directement accessible et pas ceux des autres layers.
Existe-t-il un soft sur lequel je pourrais commencer à construire l'architecture de ce contrôleur, avant même d'avoir un module Core?Tout dépend de ceux que tu veux faire. Si tu cherches un soft pour créer de circuit je te conseille vivement Eagles qui est pour moi le meilleur soft de conception de circuit. Sinon si tu veux simuler ton circuit la il te faudra utiliser Proteus ISIS qui est un excellent soft aussi mais je trouve que l'interface est moins accessible pour faire des circuits que celle d'Eagles
Il y a un truc qui me titille par contre c'est que tu utilises beaucoup de potentiomètres et que cela ne me parrait pas compatible avec un système qui change de fonction à la volée. A la différence d'un encoder ou la valeur est en mémoire, le potar a une valeur de resistance... du coup si tu as un pot a fond en mode "EQ" et que tu passes en mode "effet" ben l'effet de ce pot sera aussi a fond au moment du changement de fonction...Ce n'est pas forcement vrai car tu peux faire un fonction de "rattrapage" de l'ancienne valeur du paramètre un peu comme sur le JUNO106 ou 60 ceux qui veut dire que lorsque tu changes de preset la valeur de ton potentiometre ne changera que lorsque tu auras rattraper son ancienne valeur (je sais pas si c'est très clair). Exemple: tu bouges le potentiometres 1 sur le layer 1 jusque la valeur 127 (MAX) ensuite tu passe au layer deux et là la valeur de ton potentiometre sur le layer 2 vallait 20 (par exemple) et bien tant que ton potentiometre 1 ne sera pas egale a la valeur 20 le parametre ne changera pas. Ceux qui fait que tu sera toujours obligé de remettre "à jour" tes potentiometres. C'est vrai que l'alternative des encoder avec un led ring est beaucoup mieux car tu visualize tout de suite la valeur sur le led ring.

Salut Juice721,
1°) est-ce que les faders/pots/encoders/buttons (que j'appellerai "contôleurs dans la suite du message) peuvent supporter une seconde fonction par le biais d'une hypothétique touche "shift"?oui tu peux leur assigner autant de fonctions que tu veux. Tout depend de ton programme
2°) est-il possible d'assigner ces contrôleurs sur plusieurs layers?oui, idem à la 1e question
3°) est-il possible d'avoir des layers indépendants sur des groupes de contrôleurs (ex: 4 layers pour 8 faders + 4 layers pour 8 potards, sachant que j'aimerai pouvoir avoir en même temps le layer 2 des faders et le layer 4 des potards)?oui encore.
En fait suivant le programme de ta Midibox, tu peux assigner autant de couche que tu veux à chaque controleur dans la limite de la mémoire du processeur mais tu es loin d'arriver à ces limites.
Dis en plus sur ton projet cela pourrai interesser la communauté.

Thank you Nils for this precision but i ever try to contact Doug without any answer that 's why i ask the question on the forum
I hope he will answer soon.
-
Dear diyer,
I would like to build my own design of the MB808 but i could not find anywhere the PCB file or the eagle schematic file.
Do i miss something on the forum or the file aren't available.
Do you think Doug you can share your work?
Thank you

I am sorting my midibox stuff and come across stuff I'm not going to use anymore, that holds little to no value to me, and maybe I can make someone else happy with it.
This time it's an Optex 2x40 LCD display WITH A LIFTED TRACK AND SOME LEFTOVER RUBBISH ON THE SOLDERPADS. It is however still possible to solder directly to the (SMD) pin of the IC for this particular track and/or other tracks that turn out to be damaged. A DIL connector was soldered to this module previously and removing that did the forementioned damage.
It's free of charge of course, shipping can be done cheap. Let me know if you're interested.
it 's very generous!!
how much is shipping to Reunion?
Have you got some picture?
thank you

Dear Midiboxer,
I was looking for analog synthesizer and i found this think
http://www.leboncoin.fr/instruments_de_musique/331571618.htm?ca=26_s
i don't think this guy respect the rule of midibox community :ermm:
-
How much you looking to sell? Would love to have one!
I'm waiting that TK approve that i could sell it.
but i think about 350$ or an exchange with an other analog stuff like preamp, synth, compressor ...
-
Dear TK,
I would like to sell my Midibox SEQ V4 because i don't use it anymore.
It's complet and working, in a woodbox with a front panel from schaffer...
Ps: Sorry for the PM.
-
Look again, it's here. Just scroll to the paragraph that is titled "The Costs", you'll find all the info there.
thank you

I was looking on the web site Dorkbot but i didn't find any information about Shipping.
Someone can tell me how much is shipping to France.
thank you

Dear Midiboxer,
I would like to build some new module for my modular synth and i need professional PCB.
I saw on the web that there is a lot of different company (PCBcart, Eurocircuit, expressPCB, RayPCB...) who make PCB but i don't know which one is the "best" in price, quality, delay...
Thank you to share your experience with this different company or other.

UP!
Dear Midiboxer,
I tried to send "DCB string" (keycode 0xfe,data 0xa4 note on C2, 0xff end of the string) trough MIDI out in my JUNO60.
Like DCB protocole is 31250 hz communication ( same as MIDI BAUDrate ) i hoped that my Juno 60 played some note, but nothing happend.
I believe that the clock signal have to be send too, i'm right?
I reed this Wikipedia article about DCB protocole here
and i dont understand what's the "Busy Data"
Is there aénybody how could explain how interfacing DCB protocole with MIOS8 core
Thank you

UP!
Dear Midiboxer,
Is this project still in developement ?
I bought a matrix 1000 1 year ago and control it with my BCR2000 ( a behringer controller)
Unfortunetly the Matrix 1000 Cpu is very F---ink slow.
Any live control are impossible.
That 's why i ask if this project still life ?
Best regard,
Xarolium

Hi Midiboxers,
Thank you TK to fix MIDI In Bug
I would like to know if its possible to improve IMPORT MIDIFILE fonction.
Like you describe on the V4.0Beta19 when you import midifile every note came with the same lenght. Do you think it's possible to change it that when i import my MIDIFILE i keep the lenght note i edited on my Software sequencer.
I don't know if it's clear what i'm trying to explain
Sorry for my Frogy english

Yes je vais t'aider t'inquiète je te lâcherai pas tant qu'il ne fonctionnera pas
-
Ok
i think i'll buy some 10k potentiometer it would be the easiest solution
thank you for your help
-
Dear Midiboxer,
I just buy a Matrix 1000 and i would like to built a Chaos Matrix
I have a big stock of 10k Log Potentiometer and i would like to know if it's possible to change the AIN response to match with 10k Log instead of 10k Lin potentiometer
Thank you,
Xarolium

thx for zour fast answer
I already have the Ultracore but how did you connect the matrix 1000 in Midi?
Midi In MX1000 to Midi Out Core
Midi Out MX1000 to Midi In Core
Keyboard out to Midi In I2C
is it good like this ?
An other thing .
Why, in your din.h file do you define two time the DOUT pin 4. once for DOUT_DCO2_CLICK and the second for DOUT_DCO2_NOISE
Is it the same Led?
-
Dear Julien,
I bought a matrix 1000 and i would like to built the controler
I know that i need :
-Pic Core module
-1x AIN
-1x DIN
-1x DOUT
-1x I2C module
But i don't know how did you connect the DIN, DOUT , AIN on your Pot, Switch and Led
Could you please tell me how do you do ?
Thank you
Xarolium

Le problème est résolu
Merci votre aide (sur le forum international)

Salut Ksir,
Connais tu les modules de chez e-licktronic, il ressemble étrangement à tes modules de 8 potentiomètres
