  1. Small eschema sanity check?

    Sweet thx! Very much appreciated!
  2. Small eschema sanity check?

    I'm looking to build my own custom board, but I want to make sure I have the core concept down for a basic DIN, before I move on to adding more components. Totally new at doing my own circuits, so any input would be appreciated! When I'm done I'll post it all, in case it's useful for anyone. Thanks! basic_din.pdf
  3. kicad schematic files for MB modules?

    Oh, okay. That sounds good. Having the modules was just for a starting point to ensure I'm doing it right, since I've never attempted this before (want to try to squeeze everything I want in with less boards/cabling). I'll try my hand at tracing them and compare it to the files you have. Thanks Phatline & borfo!
  4. Okay, my google fu is not up to par, and this is my first go at KiCad, but: I've been trying to find schematic files I can open in KiCad (i.e. not pdf's) for the Midibox modules. How do you all do this? I "think" it's possible to import the .brd files in KiCad, if I use the nightly build. Not sure what's an efficient work flow.
  5. I had trouble with the MIOS_Studio download for Linux (maybe because I have the 64 bit version of Ubuntu 14). It just didn't work for me. So here's a tutorial on how to make MIOS_Studio (actually MIOS_Studio_Debug) on Ubuntu in case anyone else has the same issue ----------------------------------------------------------------------------------------------------------------- Open a terminal. Make a svn folder, and get the recent mios32 repo: cd ~/ mkdir svn svn co svn:// when it's done, unpack juce: cd ~/svn/mios32/trunk/tools/juce unzip Go to the mios_studio directory for linux: cd ~/svn/mios32/trunk/tools/mios_studio/Builds/Linux I had a bunch of missing packages that I needed to install. You can try do a make first, but I needed these: sudo apt-get install libasound2-dev sudo apt-get install libx11-dev sudo apt-get install libxinerama-dev sudo apt-get install libfreetype6-dev sudo apt-get install libxcursor-dev After that, do a make: sudo make If all went well, MIOS Studio should ready for you in the build folder: cd build MIOS_Studio_Debug If it runs, go ahead and quit it, and copy it to your desktop or wherever: cp MIOS_Studio_Debug ~/Desktop Done! You can now double click the icon and it should just work.      If Make Fails ------------------------------------------------------- If make results in an error (e.g. missing file), you might need a package or two. To figure out which package has the file, use apt-file: sudo apt-get install apt-file Then update it: apt-file update So here's an example of an error during make: ../../../juce/modules/juce_events/juce_events.cpp:55:23: fatal error: X11/Xlib.h: No such file or directory   #include <X11/Xlib.h> Find a package with this file by doing this: apt-file search X11/Xlib.h which gives you this: emscripten: /usr/share/emscripten/system/include/X11/Xlib.h ivtools-dev: /usr/include/IV-X11/Xlib.h libghc-x11-dev: /usr/lib/haskell-packages/ghc/lib/X11- libhugs-x11-bundled: /usr/lib/hugs/packages/X11/Graphics/X11/Xlib.hs libroot-core5.34: /usr/lib/x86_64-linux-gnu/root5.34/cint/include/X11/Xlib.h libx11-dev: /usr/include/X11/Xlib.h you probably want libx11-dev (libroot-core5.34 might also work), so: sudo apt-get install libx11-dev Before you run make again though, do a clean: sudo make clean and try again: sudo make
  6. button presses = +/- keyboard transpose?

    Sorry I've not been on the forums in awhile, but yes! If you've got some code to share, I'd love to take a look. I've been trying to accomplish this via the NGC file, but haven't had much luck. I'm currently using the NG app which does everything else I need, just not the keyboard octave shifting... Thanks Robin!
  7. debugging

  8. keyboard octave button

  9. Okay so I'm having a bit of trouble figuring out how to take the current keyboard range and on each successive press of a button, shift it down by one octave. It has to be relative, because I also want an increment button as well.   I'm assuming it'd be something like:   event_button id=1  kb_transpose= current_value + 12 event_button id=2  kb_transpose= current_value - 12   Sorry if this has been covered before, (I looked but maybe I didn't search for the right terms?).  Thanks for any help!
  10. Fatar. Nothing?

    Ah, forgot to add EVENT_KB... just when I thought I was getting the hang of things... :smile: Thanks TK!
  11. Fatar. Nothing?

    Okay. I'm getting closer. I have all the analog pots in place. Well, 64 of them. I still have the aftertouch, mod wheel, and pitch bend to deal with plus all the dio's. Right now I'm trying to figure out the fatar keyboard. I've tried swapping the connections, but for some reason I can't get the midibox to recognize it: In MIOS, I have this: KEYBOARD n=1 rows=8 dout_sr1=1 dout_sr2=2 din_sr1=1 din_sr2=2 din_inverted=0 break_inverted=0 din_key_offset=32 \ scan_velocity=1 scan_optimized=0 note_offset=28 \ delay_fastest=5 delay_fastest_black_keys=0 delay_slowest=10 Maybe I have the connections wrong to the KB module? All I have connected right now is just the Fatar KB -> KB module -> J8/9 of my LPC17 module.
  12. to debug

    From the album nextSteps

    My new synth. Lots of work still to go
  13. NG and AINSER64. Next steps?

    Ok. Thanks to TK, I've got everything running. My core shows up in MIOS Studio, uploading .hex files works, encoders on my DIN's transmit, and my AINSER64 looks like it's working when I upload the MIDIO128 project (albeit, missing a few pots I've not attached yet).   However, when I upload the NG project, my little green LED doesn't light up at all, and nothing happens when I spin any of the pots, so it doesn't look like the AINSER64 board is being recognized. Do I need to do some programming at this point? Totally cool to dive into this, but I wanted to make sure I'm not missing something, like, the NG should see the AINSER64 board,  but I've foobared it somehow.   Any hints are much appreciated... thx!
  14. Got it! JOY! Thanks TK... re-upped everything and all is well... now I just have to debug my AINSER64 and my DIN chain :)
