  1. Morning! I'm new in this forum. I've subscribed because i'd like to return to life my glorius Fatar keyboard. After the internal midi controller died, i'm considering to realize my own device, i'm skilled enough to deal with firmawre, pcbs and so on. Are there anyone in this forum that could give me some tipps in order to speed up the development process?   Bye, Gluca.    
  2. Hello, I've got a question! I was about to buy a small interface box for two of my effects. but when I saw the price I thought that there was probably not much in it and that I could have everything I needed to tinker with one. Someone has already opened one of these boxes? I suspect they have just put an optocoupler and distribute the logic level on the Jack outputs? And Empress call their one, midibox Thank you Bruno
  3. in our band we are playing with the thougt to record our sessions with the zoom livetrack-l12...but this have no midi... up to now we recordet only the master-track without any midi at all so my question is: is it possible to convert a midistream to audio? and convert this audio-recording back to midi? so i could use one o the 12 channels for the midi (clock start stop notes and so on) are there already devices out there? i can remember that 30 years ago such things as midi tape exist... or is it maybe a cheap trick that can be solved with an optocopler an opamp and a few lines of code?     EDIT: its done   VIDEO-Overdubbing a JP8080:    
  4. I want to implement a stand-alone variant of http://www.maxforlive.com/library/device.php?id=196 What I want to achieve: I want to select quantize grid, feed clock to the core and play live, but with getting quantised output. Has something like this been done? What's the best approach? I was thinking of using the NoteStack from MBSEQv4 and pushing/popping notes on the notestack based on midi clock.
  5. The NG and the DSP...

    Hello all, as I told in the thread dedicated to the RTP-MIDI compatible NG board I made, I added some expansion ports to the board, not only for the KissBox but also for something else on which I am working since a long time... It's time now to reveal what I am working on :smile:   Since a very long time, I work on the idea to ressucitate the Soundart Chameleon, and since the beginning, I am convinced that the MIDIBox NG CPU is the right base for it. For those who do not know what the Chameleon was: the Soundart Chameleon was an hardware synthesizer, built around a DSP56300 and a Coldfire microcontroller. The whole software base was completely opened, and it was possible to write your own synthesizer application. The bad thing is that Soundard went bankrupt, and Chameleon disappeared, which is a pity, considering that the idea was brilliant, and the price was affordable for such a machine. The MIDI part of the Chameleon was running under MIDIShare (a open concept, similar in many ways to MIOS), and it was responsible of loading the DSP code.   Then come the DSP problem... I program and design DSP boards since a long, long time for pro audio and music applications, and I know quite well that DSP may seem out of reach for DIY community. We are facing two problems : price and tooling. Almost all DSP uses BGA and other SMD industrial packages, making the idea of DIY board really out of reach for most of MIDIBox members. Making the PCB is not really a problem anymore, but soldering these chips by hand is most of the time impossible. Even "low end" DSP like the VLSI and the Spin FV-1 are SMD.   So I looked to two other solutions : recycling ASX/i-CON/Plugiator boards or use Analog Devices EZ-Kit boards For both of them, the cost is roughly the same (around 350 euros for a board - ouch!), but there is nothing to do at hardware level. If you think it's expensive, just take a look to the Monome Aleph.... 1400 dollars!!!! The Aleph is partially open source (hardware is closed source), and the software is still quite limited today (as far as I know, the Aleph only have one synth project for now). Even with a 500 dollars DSP board, a MIDIBox project would cost half this price (and would be compleetly open)   From a personal point of view, the EZKit are much better (more audio I/O, more interfacing possibilities, complete documentation available, software toolchain delivered with the kit), but they are bigger and you must write your own software (but that's where I come into the game, since I will provide the code and support for the community)   The ASX/iCON boards are delivered with three excellent software synths (the VST interface for them being simply awful however :sad: ), and they can be driven directly from MIDI I/O from the MIDIBox for simple projects. There is no technical documentation for these boards (I had to draw the schematics by myself, after hours and hours of investigation), and getting access to the DSP requires some modification (to inhibit the local processor and replace it with the MIDIBox board), but it's feasible   I have included in the RTPMIDI_CORE board the connector needed to access the EZKit and ASX boards, so the link will be very easy to make between the two boards (see "MIDIBox goes RTP-MIDI" topic for details about this board), and I am currently coding and testing the library for the STM32 to load firmware in DSP board (take care, Analog Device calls it a bootloader too, but it has nothing to see with MIOS bootloader :shifty: )   I just expect now that this project will get some interest from the MIDIBox community   I did not want to go into much details in this already quite long post, but of course, if you have any question... just ask (I am preparing some pictures of the first prototypes I made)   Benoit

  7. MIDIbox goes RTP-MIDI...

    Hello to all MIDIBox forum members,   I am proud to announce that, thanks to Thorsten work, the last version of MIOS is now RTP-MIDI ready :rolleyes: If you do not know what is RTP-MIDI, you can take a look there : http://en.wikipedia.org/wiki/RTP_MIDI   (In two words, RTP-MIDI is transporting MIDI over IP networks, to take benefit from high speed from Ethernet, plus other new functionnalities like automatic merging/splitting). RTP-MIDI is completely license free, natively supported by Apple in OS-X and iOS, and there is a free driver for Windows too. It's also Plug&Play thanks to the use of Bonjour.   The concept is based on the use of the KissBox RTP-MIDI OEM board (http://www.kissbox.nl/products_oem.html), which translates the RTP-MIDI protocol into an high speed SPI based protocol (the protocol being simply the one used for USB transfers)   Of course, final users will not need to write their own RTP-MIDI application in the KissBox CPU board, I have written this part (Thorsten included the host part and tested it for the MIDIBox applications) The first version is in beta state, we are now looking to optimize it, especially the SPI speed.   We will demonstrate the board at NAMM in Anaheim in two weeks, if you want to see it operating (we are located at booth 1088 in Hall E, for those who want to visit us)   If you have any comment or question, they are of course welcome   Benoit (PS : yes, I am from KissBox, in case you are asking yourself :shifty: )

  10. Seems Ploytec developed a succesor of the old GM5. It's USB 3.0 with up to 16x16 MIDI In/Out. It's not atmel based like the old GM5, instead it will use Texas Instruments TUSB9261. I called them some minutes before and the friendly Ploytec employee told me, that within the next half year there will also become a board available with pinheaders for the shiftregisters etc. He gave me the approval to repost the PDFs here. usb3_midijunction_sch_16x16.pdf usb3_midijunction_sch_8x8.pdf usb3_midijunction_sch_1x1.pdf
  11. openMaster Masterkeyboard

    openMaster Masterkeyboard Today, i start the development of the openMaster master keyboard. It should be a kind of clone of the "openLabs Neko". Let's bring up some features: 61-key master keyboard computer with an VST host 64 pots (MIDI controller) 16 faders (MIDI controller) built-in hardware sequencer and an audio interface for high quality output If you want to see more of it, stay tuned 
  12. Ich hab grad auf der Ploytec Webseite gesehen, da scheint es neuerdings einen großen Bruder vom allseits beliebten GM5 Chip zu geben. Hat wohl USB 2.0 / 3.0 MIDI mit bis zu 16 In / 16 Out Ports. Mehr ist auf der Seite leider nicht zu erfahren, der dortige Link ist Passwortgeschützt. http://www.ploytec.com/ http://www.ploytec.com/datasheets   Hat jemand schon mehr Infos dazu?
  13. Hi all, my MIDI electronics experiments started long long time ago, with a PIC based MIDIBox... I sometimes peek at the midibox site (I am mostly on vogons forum these days), but now it is really time to post again ... :-) I proudly announce my latest project, a successor for X1 : X2 !! - Small form factor midi PCB : 65mm x 38mm size - Waveblaster compatible connector for use on sound cards and DIY projects. - Dream 5000 series synth chip with 81 voices polyphony - Super low latency <1ms - 64mbyte flash for soundbank data - USB MIDI in (Class compliant midi device, works on Windows XP without drivers) - stereo line out using a high quality 24 bit DAC (3.5mm stereo connector) - Preloaded with a high quality 16 megabyte Dream General MIDI soundbank (http://dream.fr/pdf/Serie5000/Soundbanks/GMBK5X128.pdf) Running very well already with old games,  still working on the software to add some features allowing to tweak more. I expect to have a batch of these ready by december :-) I should make some recordings soon. What do you think ?  
  14. My Midiproject

    Hello everyone :) i'm Leon from Germany and I want to design my own midi controller. It should look exactly like that: http://www.malighting.com/fileadmin/_processed_/csm_MA_onPC-fader-wing-web_04_d5a4263569.jpg I decided to build the LPC17 based Core and use 2 DIN, 2 DOUT (60 buttons - 60 LEDs) and two MFNG module, because I want to use 15 Motorfaders from Alps. Is this project possible with midi box? Where can I buy the PCBs in Germany? I would be very happy with some feedback :) All the best
  15. Midi-in-Core > DMX-out Converter

    I want to convert Midi-In-Core (not USB-midi)> DMX-Out Core (MAX 485 Circuit) but in the DMX-Examples i read: // For now disable UART as we will be using DMX #define MIOS32_DONT_USE_UART suggest that i cant use Midi-Input then? What do i have to do to get it working?
  16. Hi, I have a Line 6 FBV shortboard MK1 that wonder if I could use as a MIDI controller for the Möbius looper software. So far I have figured out that that the pedal needs 9v (through the rj45 connection) and sends/receives serial data. Any hint would be very much appreciated :) /Lars
  17. Because my Waldorf Midibay became too small for connecting all of my MIDI equipment, I went ahead and designed my own MIDI matrix / programmable patchbay. The modular MIDIbox Matrix has up to 56 input and 56 output ports and provides a smart solution for the fact that not all MIDI equipment is usually located in the same rack or corner of the studio space.   MIDIbox Matrix features break-out boxes (BOBs) that give access to 4 MIDI in and 4 MIDI out ports at a time. These are connected via 9-pin serial cables to the main unit and are designed to be conveniently placed in the back of your rack, e.g. attached to the inner sidewall of a rack enclosure with screws or velcro tape. This means that instead of running 8 MIDI cables to the MIDIbox Matrix in order to connect four synths, you only need a single, cheap serial cable from your side rack to the center point of your matrix.   Two BOBs each connect to a single I/O board, which does all the level shifting and signal refreshing. Up to seven I/O boards can be attached to the heart of the MIDIbox Matrix, an FPGA-based switching and routing logic that is controlled via a core board such as the STM32 or the LPC17.   As the system is highly modular, it is possible to start with a low port count (4) and then increase the number of available ports by simply adding I/O boards and BOBs as needed. Fully loaded, i.e. offering 56 input and 56 output MIDI ports, the MIDIbox Matrix consists of 1x FPGA board 7x I/O boards 14x BOBs plus a core board and the PCB holding the user interface.   This is how a BOB looks like in my setup:   Software-wise, this is almost ready - everything works as expected, just the PANIC button has to be implemented in the next weeks, and some code cleanup will be necessary. You can find more documentation in the Wiki if you are interested.   Kind regards, ilmenator
  18. Midibox sid midi controller

    Hi there! i have a keyboard with 8 sliders and 8 knobs, all midi cc assignable.  What do u believe would be the optimal parameters setup (16 of them only) to control my midibox sid? Im working with two sids in a stereo config.
  19. hi all , someone knows why my sammichSID dont start up / boot up when i have connected both midi cables ? (midi in and midi out connected) . When i only have connected one of them , then no problem , but if i have connected both , the sammich dont start. Thanks. In regard to check some failure, is There any way to know if midi input and output is working ? or how do a diagnostic ? thanks very much

    Hi Guys i'm finding a man to build for me a midi box SID bassline mode Anyone interested in this??  Thanks  for your attention .. Neri Omar  ps: presslabrecordings@gmail.com   
  21. Hi, I have modded my Peavey Vypyr 120 combo guitar amp, since it only has a dedicated 8-pin connection to the Sanpera pedal, which transports midi and voltage for the pedal. To be able to also use midi signals from a sequencer to control the amp, I split the 8-pin connection up to standard 5-pin and the other three pins separate, putting a midi merger in between. Everything is documented here: http://peavey.com/forum/viewtopic.php?f=33&t=42132&sid=fa2db4d5a14f0699d076a40acd46d0ea Everything works quite nicely, except the volume pedal of the Sanpera. It does more of an on/off switching and in general is very unpredictable. I captured Midi Data with MidiOX with and without merger (see attachment, part above sysex is without, below with merger, sysex comes from switching the amp on) and can't see any difference. What I'm trying to find out now, is if there is a generic problem when using a merger in conjunction with midi CCs from an expression pedal, or if only the merger I have sucks ;) I also found this discussion, no idea if that could be relevant: http://www.diystompboxes.com/smfforum/index.php?topic=102792.0
  22. Remote BPM?

    Hi, Is there a way to change the BPM  (fire a BPM preset) with a  MIDI controller? Best FC
  23. Hi, my plug-on board dreamblaster X1 is finished now. Same pinout as the smaller S1 some use in their midibox, but much more features and larger soundbank. I sent one to Phil in Australia (3 weeks underway in post !), and now he finally made I nice review. Even though it is not a midibox, and closed source (requires NDA to buy their dev kit), I proudly want to show it to you here.  I will be starting my next project for 2016, with a dream chip, ideas welcome !! Greetings, Serge  
  24. USB to MIDI converter?

    Hi, a while ago I bought a Nektar impact LX 61 keyboard, which has an USB connector only (see bottom of http://www.nektartech.com/Products/Impact-LX49 ). That worked fine (with some latency) connected to a PC and making music with a DAW. Now I'd like to connect it directly to other MIDI devices, like my e-drum, which accepts MIDI controllers for backing parts, through regular MIDI connectors. I'm sure there is a solution to this, but I'm not sure which one will work when searching the web. E.g. there are some USB/MIDI converters like the Prodipe MIDI USB 4i/4o (http://www.prodipe.com/en/products/interfaces/item/60-interface-midi-usb-4in/60-interface-midi-usb-4in), but USB seems to be dedicated to PC only. I'm not sure if USB/MIDI cables with integrated converter will do (e.g. http://www.thomann.de/gb/terrasoniq_midi_one.htm ). What I'd like to have is a stand-alone solution, which converts the LX's USB connector into a regular MIDI connector, so I can plug it directly into other MIDI devices. Power supply from the solution would be nice to have over USB, as that's the LX's normal mode - alternatively I could attach an extra power supply to the LX (right left to the USB port). [error: that's for a foot switch] I welcome your suggestions ; -) Thanks from Germany, Michael
  25. Hi everybody, After have build SEQ v4 with STM32F1 with options (ethernet / 4x IIC midi / AOUT/ BLM port) no wilba CS/ homemade frontpanel (lots of DIN DOUT) some years ago... (and working very well) I'm building a new SEQ V4 with STM32F4 and Wilba CS/schaeffer frontpanel with: Line Driver transmetter 2x MIDI IO IIC Midi ethernet card from the fist seq BLM port a separate rack with Line Driver receiver ,AOUT and DOUTx4 for gates/triggers Questions: I don't find informations for the BLM port with STM32F4! someone say on a forum that the second MIDI IO will be for this purpose: what is the best way to have BLM port with STM32F4? how to wire? Is MIDI IO with STM32F4 provide 3V or 5V midi ? (does the MIDI IO stuffed with 220 ohms or 47 ohms resistors R3 R5 R8 R10?) Is the config of LineDriver is Plug n' Play? you could use the seq without Line Driver receiver or have to plug parallel port permanently? Thanks
