  4. Am i allowed to sell stuff containing a midibox ?

    in Miscellaneous

    Posted

    Hi there !

     

    i've made a pedagogical musical installation in a school, called "Végétophone". It's working beyond my expectations and i've been asked if i could make a small series of a suitecase version that would be bought by music schools, libraries and venues. Since it contains a midibox in it i(amongst other things) was wondering if was allowed to do that. It's a purely non-profit project of course.

     

    By the way if you are interested you can watch these :

    Thank you !

  5. AINSER64 problems

    in Testing/Troubleshooting

    Posted

    Hey, thank you so much for the detailed answer. 

    Under the pressure of the emergency, i had to find another solution. So i made a few phone calls and found an arduino Mega, it seems to be easy to do (no midi), so i'll go this way.

    But i definitely will build other midibox projects, so i'll eventually sort it out !

    Again, many thanks, i really appreciate.

    Help !

    I tried a new cable orientation (see picture) but it behaves the same way...

    By mistake i broke one of the MCP3208 pin.... you can see it on the picture as well. But i assume it should work anyway, since this pin is for CH0 (pin1), so it just broke J6, right ? Otherwise, if i find another MCP3208, i can just replace it, or does it need to be flashed ?

    Last question : i didn't edit my midi128io settings regarding AINSER, i thought this might be the issue. is it supposed to work by default ? (i don't have any LCD connected so i would edit in openoffice)

    This is urgent, very urgent...

    Thank you very much

    Hey thank you for your answer ! By IC1 and IC2 you mean MCP3208 and 74HC595 ? Which pins should i test ? Between 15 and 16 ?

    And just to be sure : it should be working even without anything plugged in my analog inputs, right ? (in my case, J6 and J7).

    Thanks, i'll give it a try tomorrow, since i think i am still on v3.0.12. Hopefully this could be the issue.

    The link led never flashed. It's just stays on. Or it just stays off, sometimes. When i plug/unplug/replug the J19 several times, the link led is most of the time staying on, but maybe 20% of the times, it stays off.

    When launching the jitter monitoring app, i've got nothing but -- everywhere. when i unplug the ribbon, i've got 4095 for min and max and 0 diff. when i plug it on, i've got 0 min, --max and 0 diff.

    I'll come back here tomorrow and let you know !

    Thanks,

     

    i mean, it stays lit. sometimes when i start mios studio after plugging the midibox or whatever, it remains unlit. Anyway, it's never been slowly fading. I've tried the jitter monitor application, it didn't show anything (although i'll redo the tests today).

    Hi,

    i'd like to have some help with my AINSER64 used in a MIDI128IO config :

     

    i've mounted the unit, 'shortcuted' several unused inputs. When i plug it to the core, the yellow and red lights light on. But the green 'link' one sometimes remains lit, or unlit. that seems to indicate a problem.

    In MIOS Studio, i see a bunch (i guess 64) of CCs going to 0 when i unplug the AINSER. Any idea of what i am doing wrong ?

     

    Thank you,

  22. MIDI IO 128 : Can't get DOUTs work

    in MIDIbox HUIs

    Posted · Edited by chapelier fou

    do you have the DOUT / IN PCBs with 4 registers upon? the ones i got from SmashTV have a DIL 10Pin Header and the DIN are to be connected to the Front Row and the DOUT to the Back Row. DOUT are Connected to J8 and DIN to J9.

    did you already see those schematics:

    http://ucapps.de/mbhp/mbhp_doutx4_32leds.pdf

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

    Thanks, yeah, i've seen this. So how are you supposed to wire them from the J8/9 connector ? Split it in two ? Also in this DOUT schematics, the ground line is spotted on J5, but i assume it's on all of them, ain't it ?

     

     

    Hi Louis,

     

    Have you tried to connect only your DOUT chain to the J8/J9 connector and then from MIOS STUDIO typed in the command “set dout all 1†to your LPC17 core and see if this works? I suspect that you have the older DIN card R4 or earlier that has a wire missing to rout the output data thru the DIN card. The following came from the change log of the DIN board R5 from SmashTV.

     

    Routed SO from J1 to J2 (so a DIN:DOUT chain is possible)

     

    To fix this add wires to all your DIN cards on the SO pin.  This should allow you to dassy-chain your Din & Dout cards.

     

    Pete

     

     

    Didn't try this specifically, but did try with only a DOUT connected and played midi notes from ableton live : my led never flashed.

    Anyway, thank you very much, it feels like im on the good way, just need to clear my mind and unstress a bit...

    Gonna keep you informed ASAP. I let my gear at the school im working in. 

  23. MIDI IO 128 : Can't get DOUTs work

    in MIDIbox HUIs

    Hi

    I getting desperate...i've assembled my MIDI IO128. Got 4 DOUTs and 4 DINs.

    Everything seems to be working, recognized by the computer etc. I can produce notes in with the DINs as expected.

    The thing is i want to use the DOUTs to turn leds on and off when receiving notes, but no success. I just don't know how t wire the DOUTs.

    The weird thing is that in the MIDI IO128_v3 interconnection diagram, the J8/J9 is split into 2 5 pin connectors. I can link my 4 DINs in series and it works, but no luck with the DOUTs. 

    Any help ?

    thank you
