  1. Need a little help with configuring asm for testing (UPDATE)

    in MIDIbox Tools & MIOS Studio

    Posted

    Ok I've been away from this longer than I would have like, but I'm finally back to testing. Before I go and ruin anything, I've got my Core and one DIN module with only one button connected. Do I need to remove all the other chips and ground unused pins back to VS (while using this srio_interconnectTest)? Or am I good to go with leaving the chips in and not grounding anything?

    Thanks for any help, I hope to get it all going over the weekend!

  2. SparkFun ButtonPad PCB for MIDIbox64

    in MIDIbox HUIs

    Posted

    Woop! Thanks for letting me know!

    It's a good job because I just went and photoshopped up a circuit board for it (based off Exported Eagle images, so should be to size etc). See attached.

    For all you DIY Etches, is this going to be possible, or are the tracks too fine? Theres room to make them bigger really, so I could do that. IF DIY is possible, I was going to head down the route of Laser Printer, would this be ok, if not tedius? Or should I really be looking at exposing the boards?

    Thanks for all your help guys/girls! I'm starting to see the end of the tunnel.

  5. GM5: Least-cost USB-MIDI Interface Chip for 4.50 EUR

    in Bulk Orders

    Posted

    Nope, mearly asking if there's an estimated time...

    As in are we looking at a few weeks or a few months. TK if you did happen to take that as badgering I appologise. I know that you're doing all this to only further the community, not your own wealth and it's very much appreciated, so I would never go out of my way to badger you or anybody on this forum and hope it wasn't taken that way...

  10. Need a little help with configuring asm for testing (UPDATE)

    in MIDIbox Tools & MIOS Studio

    Posted

    Hey people,

    I'm making a MidiBox64 and have built a PIC based Core (with LCD) and 1xDIN Module, uploaded the MIOS and installed the midibox64 app. Originally the LCD just cycled through a hundred messages a second, so had to edit the asm file, compile the app again and upload it. Now I get: int N and a load of squares, the first of which is flashing on the first line, then on the second I get: @Reverb # 1  64. I've tried with a piece of wire to make the connection between several posts on the DIN and the corresponding ground (vs+d4 for instance), but can't get it to send a midi message (whats the best app to use for OSX that will monitor MIDI, instead of me jumping into Traktor and pressing the midi learn).

    I've attached the asm file I'm using, if one of you wouldn't mind having a quick look at it to make sure I'm not being stupid, or give some advice on which posts to test. I just want to get one button setup to send a message to my computer then I can continue with the project.

    Thank you very much for all the great info here, as well as the replies to peoples questions in the forum, i've spent most of my time trauling those for information. Any help would be greatly appreciated.

    Thank You

  12. Confirmation of DIN Button Wiring

    in MIDIbox HUIs

    Posted

    Hi everyone, I'm just starting to think about some custom PCBs (as well as some test buttons first) for my MidiBox and need to make sure I'm on the right track.

    Looking at this:

    http://www.ucapps.de/mbhp/mbhp_dinx4_32buttons.pdf

    Can I wire up my buttons in strips of 4 using each vs pin?

    So four buttons connected to pins 1-4 and their grounds connected back to vs on each strip? Instead of only using the vs on J5 and J6 in a chain?

    May I also ask while I'm on the subject (and pardon my lack of knowlege, I am learning electronics as I go), what is the difference between the #numbers and the others? Can they still be used the same way? Why are some called snapshot, exec, right, left, F1, F2 etc.. and the rest are just numbered?

    Thanks for any info, I'm progressing quite quickly with my project, but don't have any prior experience to make judment calls.

  13. Have I been stupid? MIDIbox64 + LEDs

    in MIDIbox HUIs

    Posted

    Hey everyone, I've just completed my first core and everything seems to be going fine, apart from this nagging feeling I have about LEDs.

    My controller will have 47 buttons and 14 pots (61 total). Each button is going to be illuminated with a single colour LED that I want to be able to control with the software (traktor). How are these connected? Am I going to have to hook up a second core to do this or am I missing something?

    Thanks

  14. Upload Mios Error - Received SysEx message of less than 8 bytes

    in MIDIbox Tools & MIOS Studio

    Posted

    Hey guys, I managed to successfully get my midicore working (well the LCD is saying READY), so all good there. The Audio8DJ doesn't work with SysEx messages, I'll add it to the blacklist, but my axiom25 worked fine (maybe it's a good idea to have a list of interfaces that does work).

    On the point of the blog I mentioned, I will of course add to the wiki when appropriate, but the point of the blog was to just document the making of my own controller and give a bit of an idea of how it is made. So things like, to start I got this kit from Mikes, it includes a core that does this, a couple of douts that do that, a GM5 to make it into a USB device etc. I won't be linking specifically to mios files etc, just mention that I had to upload the mios and what it is, with a link to the main download page here and the wiki page on it.

    Is this ok? It'll be pretty non specific, just bits and pieces of information on what I'd just done, how and why to give people a bit of an idea and send them back here for digging more.

    Along the lines of this one: http://noofny.blogspot.com/

    I only read the first few posts of there but it helped me understand the process a lot and convinced me to go out and get the kit from Mikes.

  15. Upload Mios Error - Received SysEx message of less than 8 bytes

    Thanks TK for all your help and also for setting up this amazing community/project!

    I am currently in the process of documenting all of my findings/progress and hope to start a blog in the next few days to help beginners like myself out. With the intention of having a more step by step instructions of the building process and information for people without prior electronics experience.

    I hope you don't mind me doing this and I will refer back to uCApps throughout obviously.

  18. Upload Mios Error - Received SysEx message of less than 8 bytes

    in MIDIbox Tools & MIOS Studio

    Posted

    I have come to the assumption that it's the midi Cable. I'm taking it back tomorrow and just getting 2 midi cables that should connect either through my NI Audio 8 or I believe people have had success with Axiom25's, even if it does sound like a pain to get setup.

    I'm using this interface:

    http://www.maplin.co.uk/Module.aspx?ModuleNo=48612

    The only other alternative without ordering online was a ESI MIDIMATE which is on the list.

    I can't believe I forgot to put what OS i'm using, sorry about that, I am running the latest version of OSX. If anyone knows of an interface that definitely works (maybe on ebay.co.uk) then I'll order one right away.

    Thanks again

  19. Upload Mios Error - Received SysEx message of less than 8 bytes

    in MIDIbox Tools & MIOS Studio

    Posted

    This is the first MidiBox I've attempted, so forgive me if I'm a bit of a noob.

    I have built a pic core with LCD module and PIC18F452 from Mikes shop. Connected the core through a Midi/USB cable and it appears in Mios Studio fine with the Midi In Monitor showing the "SysEx: F0 F7" message every 2 seconds.

    I then downloaded the "mios_update_v1_9f" and tried uploading "update_without_installed_mios.hex" which starts, but I get this error:

    Received SysEx message of less than 8 bytes.

    I've done a search in the forums but can't find out how to fix this. Any help would be greatly appreciated.

    Thank you

  22. Program Midibox using another midicontroller as USB>Midi convert

    in MIDIbox HUIs

    Posted

    Thanks for your reply, i'll check the blacklist.

    But can I not just use say my Audio Interface which has Midi IN/OUT and connects to my computer through USB as a MIDI>USB converter or will the fact that it's a device in itself screw things up? I haven't managed to get to the MIOS yet as this is my first time and I'm just finishing building the core now, so sorry if it's a stupid question.

    Thanks

  23. Program Midibox using another midicontroller as USB>Midi convert

    in MIDIbox HUIs

    Posted

    As it says on the tin. I currently don't have a USB to MIDI cable like the MIDIMate interface, but will buy one if thats the best option (I went to get one today but they were out of stock). Could I instead use one of my existing controllers? A XOne1D, M-Audio Axiom25 keyboard or the Audio8DJ sound card. Then use their MIDI IN/OUT to program my Midibox64?

    I'm waiting on the GM5 orders to finish the project, but in the mean time I'd like to see if I've screwed the Core module up or not :)

    If I should get something like the MIDIMate then I'll order one straight away so I can get going with the programming side of things.

    Thanks for any help

  24. UK Noob Needs Help/Advice on sourcing parts

    in Parts Questions

    Posted

    I've been doing a lot of reading but am not entirly sure of the complete list of things I need.

    If anyone has made a midibox64 in the UK and knows of a good place to source all the parts, could you let me know.

    I'm after building the core board to get started with some crappy buttons etc as research before attempting a proper controller.

    Thanks for any help.
