I made the same question few months ago. Although I figure how to make my own LED ring PCB layout, never finished the layout on Eagle (Very lazy here because *finally* MIDI controllers are cheap in my place)
Just thinking if we can design a similar board that fits in a MIDIBox project. Some sort of breakout board for LED Ring + Enconders (further run a bulkorder or maybe smashtv or mike can start to sell it in the similar fashion of sparkfun´s breakout boards), anyone up to?
-
Exotic concept. But I think its hard to consider it functional, no?
Maybe in a bigger layout it can get the attetion from the public in a live experimental situation.
-
just thinking loud in my previous reply, sorry to ressurect the topic
Then again, I /still/ have to finish my rackmount MidiBox SID :)
How about to get your bunch of chinese guys as well? So you could have the help :)
hehe just a bad joke. In fact I know nothing about politics and globalization or worldwide market. I barely turn on the TV to watch the news. Actually I turn on this thing only to watch DVDs for kids with my son
Yes, all announcements and releases were made at NAMM, at least for me, better than expected, perhaps because it was the first year that I followed the event with more attention.
On the subject of old analog DJing I don´t know. I was djing in a public party this last weekend, where the emphasis was playing the music from the vinyl. That caught the attention of a cult audience, but much of the public does not care to be vinyl or not, just want a song to dance.
Besides being a thing that isn´t cheap (that accidental scratch on the surface of that rare vinyl, how to replace the vinyl? Where you can find another?) Is time-consuming transportation. My setup of midicontrolhers for that party fit in a backpack. And the setup of the tt´s occupied the entire back of a car.
There is always an audience for this type of analog DJing, DJs and some are even trying to resurrect the the vinyl scene on my country, but I don´t see a promising future for this, based in what I said above. Although this opnion is based on the reality that I see in my country it have a little bit of opinion coming from the world scene that I can follow. I have not seen much news on analog DJing at NAMM. Maybe I´m very wrong and probaly missed something
No way I´m trying to be negative about what vinyl is. A better feeling to find a cue point with this artifact spinning on a turntable, I think no jogwheel can emulate :)
-
In the controller side I like the modular way and sincerely hate all-in-the-same-box MIDI DJ contollers, (such as Vestax VCI 100, Kontrol S4, Hercules, etc)
Heh
Behringer beats me on the running to build the ´´first worldwide modular dj controller´´
I wish I had some chinese guys to build me my projects in just few weeks :)

Anyone that used the ledring feature and have did a Eagle PCB layout with such feature, could share it?
Sorry if I have missed somehting, but I have searched a lot..and didn´t find nothing. Only came across with this, but i think it´s not useful for a MB project. Anyway it is a bit pricey
I know I´m asking too much sure to avoid some hands on the work and save time....buuut

As an update, I went ahead and sprung for a Reloop Digital Jockey 2. Seems like it has good build quality for the price and I was able to score a used for a pretty good deal. Thought about the super lightweight offerings like the DJ2Go but I actually wanted to use my NanoKontrol a bit less and have a bit more room. It was feeling awfully cramped.
Still want to make my own SFX box though at some point. Since I use Traktor, it was going to be basically just a 4x4 Button/Knob matrix thing perhaps plus the effect enable buttons for the decks. Have a ways to go before I'll get to that though.
Hi
Ah, never heard about reloop dj2. Cool design.
The Twitchy I had seen some previews but missed completely the release. The touchstrip concept is nice. That´s exactly why I got a ipad, to have something similar to seek track positions in traktor. Before to have the tablet, I was doing that function with a old pocketpc and Theresa(not so cool but functional). But doesn´t matter that cool concept and a deficient audio output.
Keep us posted about your Traktor FX box. Mine should be a bit complicated. at least for me. Planning to use 2x20 LCDs, encoders and ledrings. Never did a MB project before with such features.
Cheers

Hello
Since the last year I have been DJing in few gigs too.
In the software side I have tested all DJ softwares and best choice for me was Traktor Pro 2
In the controller side I like the modular way and sincerely hate all-in-the-same-box MIDI DJ contollers, (such as Vestax VCI 100, Kontrol S4, Hercules, etc) so I´m using a nanokontrol as well, only for the FX rack + Decks Volume + Pitch control.
For the Sample Decks + EQ I´m using other small controller: the Novation Nocturn
Recently got a Ipad (+ TouchOSC) specially for music production & live performances, so basicaly my TouchOSC layout for DJing consists in buttons for browsing the tracks quickly, faders for seek track postion in each deck, tempo controls, play/pause + cue point buttons and 2 encoders as jogwheels. Didn´t have time to stick deeply in TouchOSC yet, so my layout for DJIng is quite simple. I´m planning more control over FX and other random stuff in a bigger and multipage layout
Anyway I´m not happy 100% with this setup, and I´m planning to build a modular dj controller for Traktor 2 Pro, if I have some free time . Not a monster project but mainly for FX and Deck controls (I´m planning to mix with an external mixer in soon)
In your case, as you mentioned you may build your own controller for DJing, I would suggest the Numark DJ2Go, it is very cheap and is not a big investment. They look like a toy, but everyone I know who owns one of that tiny controller have no complains about it, and in every review I read have said it is strong. Also I think it fits nicely together with a nanokontrol, phisically speaking. In fact I almost bought one of those, but had my choice with the iPad.
Cheers

HI
Yes, I had read about rasteri´s scratch controller few times before.
Althought I must PM/email him asking how precise his controller is and other few infos, some thoughts come to my mind:
1- Still MIDI, and if I remember correctly, In previous discussions on the forum, MIDI have a limitated baud rate when it comes to translate real scratch routines. Old threads though, it can be different now with MIOS32 over new Cores? (stm32, lpc1769)
2- On the wikipage, he said the CC MIDI messages coming from his precise jogwheel is natively supported in Traktor 3 and MixVibes only. Traktor is the industry standard, yes, and I don´t know too many people in the digital DJ realm that go to a serious gig with other software. However, if it have support for timecode tones, other industry standard could be included. eg. Itch Serato DJ software. Also he didn´t mentioned other versions of Traktor could support such CC events. Timecode tones are largely supported for all DJ softwares.
yet, rasteri´s scratch controller is a good basis of learning for a timecode emulation system via hardware
What approach you suggest to make a similar hardware system based on that app?
hope to listen more suggestions :yes:
-
Hi
I finally got my tablet and recently got this app:
It´s a emulation system for Timecode Vinyl System.
Of course the feel of turn the vinyl on the screen surface sucks.
I wonder if similar system could be done with a Mcu project (Midibox plataform preferably).
Like make that app a real hardware. Eg: A jogwheel with a optic sensor in a ADC system under MCU, sending a tone for a DJ software/Timecode interface.
It could be the definitive solution for the *poor* scratch system under MIDI. Also people could have a timecode system under their little knobs/jogwheels, for instance. So, avoiding the pain of carry their turntables up and down.
What approach you suggest to make a similar hardware system based on that app?

uuf isso parece que tá as moscas
Para não terminar o ano sem nenhum post por aqui, e para quem ainda não sabe...
LPC17 Core me chamou atenção principalmente essa semana com o projeto meio jovem todavia muito interessante do Sd Card Sample Player.Porém achei a revenda do LPC1769 aqui no Brasil por acaso procurando revendedores da fabricante de produtos para Mcus, a MikroElektronica
Mouser parecia a única opção para o LPC, ai tá outra, parece salgado o preço mas se você é ancioso como eu, então :thumbsup: . Talvez saia quase o mesmo preço da Mouser, se você contar que seu LPC1769 pode ser retido pela alfândêga
/edição: por favor não compre todas unidades do estoque antes do dia 20/12, data que eu recebo meu famigerado e tão aguardado décimo terceiro

Sure. I really don´t know why people don´t care with this functionality. There´s hundred of old synth-modules going cheap, such as the ones from Kurzweil, Korg, etc, that only have the DIN5 MIDI in PORT (of course). Also, Midibox synths just have that port.
Thanks for the link! The product looks very new also pretty expensive. But I´ll consider that as a option. Actually it´s the price of the solution to convert USB to old MIDI DIN that I´m using (Netbook running a MIDI router software + Cables)
Looks like the best and simple solution is plan the setup to the the old MIDI. Eg, buying a new keyboard with the DIN MIDI
Or just pray for someone experienced in the MIOS32 programming make such solution for the convertion :whistle:
-
Hello
Another issue is driver compatibility. There is a "standard" driver for MIDI devices, but many devices come with their own private drivers.
I understood about the ´´host/driver compatibility´´ mentioned. But, thinking around, Instead of a ´´generic´´ USB MIDI out to old DIN MIDI Out converter, that could convert all kind of messages from all gears that have a MIDI USB out, it could be possible (and easier maybe) to develop just some specific solution for some specific host? Eg. Something to convert the USB MIDI out from a Axiom keyboard (a good example because it is a keyboard which sells a lot) to the old MIDI style socket (DIN)? It only could read the MIDI from that keyboard, no other. Convert, then throw it to a old DIN MIDI out port.
Sorry for resurrecting this thread from the last year, but I´m get more and more intrigued with this subject. I wish it have a commercial solution for this, but I can´t find.

I'll just make it simple and handdraw the pcb with a permanent marker
yes it works, for simple circuits like a psu it could be done easy. In fact, back in the day, most of hobbyists did in this way. At least those I know
seriously : the ironing technique works ???It´s all matter of(kind of paper + experimentation) x patience. Of course it will consume some time. But 2 years is too much. :-)
PIC burner transfer after etching in ferric chloride. Done some time ago. 2 days of experimentation. Coated paper used here (250 mg)
I bet that those guys with high rated replies have better transfers + etching jobs better than mine :-)
-
So what hapened with the non-profit thing?
Should I start selling some built projects too? For instance, I bet that some MF based projects could help me to reach the budget for my first automobile :whistle: (I´m just kidding)
-
3) 1) and 2)
ROFL! Yeah it´s just a few steps troubleshooting that
Anyway tweaking the contrast pot could solve the problem after the number 3 :-)
after that, a good point is about uploading the LCD interconnection test application to check if everything is ok on the cable/soldering job between the core and the LCD

MIDI Implemantation on 3xOSC is fine. I can confirm. All parameters are MIDI-Controllabe due to it´s a native FL Studio plugin.
Just don´t expect some sort of Auto mapping from FL Studio :)
I used to play with 3xOSC few years ago. I like it even it was a simple FL plugin (in the FL´s sdk have a similar source stuff). A lot of stuff to tweak on that tabs that make you create unique sounds.
Encoders, yes, those will handle with all windows tabs from 3xOSC on the same control surface, also you could use your controller in other FL´s native VSTs that has the same tabs (Eg: FL Sampler, Granulizer, TS-404, etc)

Sim, ainda midoxeando com certeza, pois DIY no Brasil não é lifestyle e sim necessidade ;)
Até onde eu sei, um core com um PIC não vai lidar com velocity mas posso estar enganado. Porém se você não se importa com isso, ou mesmo não sabe o que é (me desculpe se sabe, acabei de sair de um forum no Orkut onde um usuário achou que seu Oxygen49 novo estava com problema nas teclas, por pura ignorancia sobre o que era velocity), volte em ucapps.de e leia mais. Não esqueça de ler com calma a Wiki. No meu ponto de vista ucapps.de é uma leitura mais técnica porém na wiki é que se concentra um grande numero de informações para iniciantes. Dica: Pesquise sobre as aplicações que tem que usar. Posso até esclarecer algumas dúvidas, mas lhe ajudar por completo vai custar meu precioso tempo para os projetos e lhe tirar grande parte da diversão e do aprendizado. De qualquer forma, o tempo x dinheiro que vai perder pra fazer tal projeto de adaptação aconselho a comprar um teclado comercial. Mas pode ser que você queira algo bem personalizado, não sei.
Não vai precisar programar um PIC. Há não ser também que queira aprender isto. Entre em contato com o SmashTV por sua pagina. Ele pode lhe vender um PIC pré programado (Espero que ele não me culpe por causar mais spam na sua inbox!). O link você acha facilmente no forum/wiki/ucapps/blog. Ele tem quase que todas as placas/modulos à venda para os projetos daqui e tenho quase certeza que ele envia para o Brasil. E a qualidade de suas placas é insuperavel à um trabalho de confecção de placas caseiras. Você vai agardeçe-lo quando tiver que desoldar aquele bendito componente que vc soldou errado, sem nenhum problema. :)

in my case in a mb64, after (4x)check all i had the randomness due to some bad quality pots. You could check yours. Just a guess

So...I hope you guys remember this bulk and not use all OPLs chipsets in the new FM sammich thing. :twitch:
Any perspective when we can have the chipsets?

Here in Brazil the cost of this axiom is about R$ 850,00 (something arround $460,00), I really prefeer to build my own keyboard (pic based core is something arround $25,00 and each module are beetween $10-$15). And I can customize the layout and design too hehehe...
But thanks for the reply :D

Sorry for the portuguese on this reply for the english speakers. It's clear my english is that bad. I'd prefer reply to him in our native language.;)

E ae BlackTXandY
Cara, se eu não me engano não existe nenhum aplicativo para o Core8 (Core c/ PIC) que lide com velocity, after touch, etc. O que é essencial em um teclado para uma performance profissional. Se você quer só eventos Note ON / OFF, dai sim pode usar o aplicativo Midibox64, Midio128, ain64_din64_dout128 . Fora isso só tem um código fonte , que pelo que eu li no readme.txt, lida com velocity mas escaneia apenas um pequeno número de entradas, e é recomendado apenas para drumpads, não alcançando escanear uma matriz de teclas de um teclado.
De qualquer forma, dê uma olhada neste aplicativo
Se você for bom programador em C ou Assembly talvez consiga fazer um aplicativo para isso ;)
De outra forma recomendo mesmo comprar um axion25. Pense, você vai ter que comprar oitavas do seu teclado, que são bem difÃcieis de se achar sem ser em grandes centros urbanos como São Paulo e Rio de Janeiro, matriz de contatos, e vai ter uma bela de uma trabalheira para montar um circuito de fiação (impressa) para essas teclas, ou ainda reaproveitar um teclado usado e mesmo assim ter muito trabalho para reaproveita-lo e adptá-lo a plataforma Midibox. Não estou te desencorajando, mas te digo, vai perder um bom tempo e algum dinheiro com alguns erros inevitáveis em um projeto de tal complexidade.
Mas a escolha é sua.
Um Axion25 não é tão caro assim. No mercado livre tem uns bem baratos, novos e usados, e até no ebay, mesmo arcando com custos de importação sai em conta. Eu mesmo estava precisando de um teclado e comprei um controlador Michael por R$300. Ele só vem com 3 oitavas com teclas grandes e sensÃveis a velocity, porque pitch bend, modulation, knobs, botões é bem fácil se ter em uma caixa a parte com um PIC, não? ;)

My main parcel insurance provider finally added Brazil...
Ah Muleque! :frantics:
Good that you have said that oficially. Lots of people here been asking where order the boards. I was always confused to say because I didn't know you was suporting BR oficially. Now it's real. :ahappy:

Hi
Marcos, an brazillian midiboxer have built a traktorizer unit. He collected the info along his building and stored online. You might check those files if there is something usefull for you

a "light wighted" firmware will also make it easier for other people to create derivatives, e.g. special adaptions for other DAWs
No doubt. If there's a way for a integration with a MIDIBOX and the FL Studio, I'm in. Because unfortunately the DAW I have adopted for a mass production, that is the FL Studio, do not have such API or something for freely bi-directional MIDI communication. There's some limited tools on the FL that helps with MIDI, for instance the Dashboard and the FL Synthmaker, but nothing beyond if I'm correct. It is a frustation having a huge MIDI gear, like a MIDIBOX in the hands... and a DAW, that you have became addicted to the workflow and not too much things on it to respond to the all of features of your gear. That's how I feel.
I was thinking to drop on the MB forum my complains about this and maybe invite FL users interested in solutions for a better integration with their MIDIboxes and the FL Studio. I think I'll create such topic in soon.
Btw...nice to see you are back to the action, ultra!

Since I'm in need of some custom MIDI monitor/ filter tools and I'm a bit without patience to jump in a programming language that I'm totally newbie, I'm thinking to use VB to get my deal.
Funny, I came to this thread via Google, when I was searching some code examples. Unfortunately, the links are broken. Both for Pablop's sources also to the Mabry ActiveX controls. I didn't find the Mabry MIDI Controls anywhere (however I didn't have try the waybackmachine). There's a page on sourceforge.net that they said, if I have understood well, now the controls are free, but the compressed file available for download are free of controls! Then, searching a bit more, I had see that the Mabry software page still charge $99 for the controls.
I think I could do all the work done via some Windows APIs for MIDI but today just having a look in my backup files from the last year, what a surprise..I already had downloaded these files from this thread last year.
So I'm re-uploading them.
Hope it helps in the future for a VB programmer/developer
Portuguese? Anyone?
