" you may also need to put the hardware config file on the root of your new sd-card: i guess its a wilba without track-position LED-Matrix? then this is the hdwg-file: /midibox_seq_v4_096/hwcfg/wilba/MBSEQ_HW.V4 (is in the zipped firmware) " i already wrote where it is (read! and take it serios), it seems that you dont have a Wilba-Interface, looks like a standard DIY-Interface? i would first try to go into bootload mode via.: http://wiki.midibox.org/doku.php?id=home:mbhp:module:bootloader-switch build this switch, set the switch to bootload mode, reboot the core, then open mios studio, upload new SEQV4 code.

ok i am in austria... so maybe a other one?

in a eurorack:

where you located?

I tryd this Variant for Midi-OUT Activity LEDs... as it works with NoteON-OFF Messages, it comes to its limits when transfairing high datarate - like midiclock. The steady Charge and discharge of C5, messes up the Datasignal, so it cant be used. Since i already used all Pins of 74HC14, i now need a second HC14, or some other Buffercircuit (for 2x Midi-OUT Activity LED) - any Ideas for that are welcome!

quick update... i debugged Rev.A with a view Wires (and it works - almost), by doing this i made Rev.B - and updatet the wiki. For Rev. B i have to Cross J1 to J2, since i made a 1:1 Connection between this 2 Headers... - and that is not true... true would be: I2>I4, I4>I2, O2>O4... and so on

yes they worked... and it looks very nice... i highly recommend latigid onś Display driver: http://wiki.midibox.org/doku.php?id=display_driver i tryed the multiplexing via J10B with a DoutX4 but i had walking lines here and there, so i took the display driver and it just works! This is the pinout from the display driver J1-J8 to connect 4 screens aka 2 PCBs to it. i made a video (build) - but i want to write some code first, so i have unit which i can work with it (to have a video jam for it...) so you can order at least the PCBs - this take some time... in the meantime i change the frontpanel: i would remove the mounting holes for the LRE8x2 first...

daily... have tok reload the side then it works

currently working on V2 (now with Displays), wiki and programming currently on development.... http://wiki.midibox.org/doku.php?id=msq-cc-lre-v2 much to programm... but it combines the last modules i designed - to get it into Eurorack...

ok kenn mich aus... das panel wird erst entworfen natürlich möglich ist so wie ich das sehe ist das einfach ein http://www.ucapps.de/mbhp_midi_io.html nur halt 2 auf einer platine die line driver von midiphy kannst auch verwenden (obwohl ich einen da hätte den ich nicht mehr brauche - weil ich zwei habe) vom midiphy core her weis i ned- müsste pin compatibel zum Discovery Board sein. - aber das orginal könntest auch von mir haben. http://www.ucapps.de/mbhp_core_stm32f4.html da wäre halt sd slot und usb gleich auf einem board... musst selber nachmessen was von der größe her eher in dein Wunschgehäuse und Anschluss Panel passt. @ gate: direkt aus dem gehäuse... ja entweder via Linedriver für extern - oder via DINX4 intern http://www.ucapps.de/mbhp_din.html oder du baust dir https://www.midiphy.com/en/shop-details/121/50/seq-v4-eurorack-modules-essential-kit-midiphy-seq-v4-eurorack-modular-midi-cv-interface direkt ins gehäuse. für CV eben auch das midiphy module, oder halt. http://www.midibox.org/dokuwiki/aout_ng und dann verkabeln zu buchsen ihrgendwo im gehäuse (da hät ich was daheim falls die auflösung für dich reicht) in beiden fällen brauchst halt dann im sequencer die +-12V um das CV von 3V raufzuskalieren zu verwendbaren werten...

tirol... oberösterreich - ok englisch ist nicht dein ding - guad ich will doch nur die Anschlussblende sehen aka Backpanel diese Rückansicht z.B. ist für ein core stm32F4... und ist offensichtlich für 2x Midi IO Module geschaffen für diese ausführung hätte ich alles daheim, bis auf das zweite MIDI IO...

nope that is a plastic case made by ponoko... so why you dont post the panel - else i am out! why you want to use the midiphy core? use the orginal core? I ask because i have booth at home the lpc17 core (need different packbanel) the stm32F4 core '(need different backpanel)... the orginal stm32F4 core use the same microcontroller on a different developement board - like the waveshare from midiphy... ... i too have the linedriver pcb... i have a whole midibox labor with assembled modules at home - but if you wont show the backpanel - i cant help you anyway...

nope i cant find it - this is only the frontpanel. i need too see your backpanel - aka the housing aka the aluminium plate for the connections... - about software: there is still a firmware for 4.096 so yes possible...

show me the connection panel of the device - so i see for what Core - Line-Trans it is build for...

@latigid on http://www.midibox.org/dokuwiki/doku.php?id=display_driver i have 2 off your boards assambled, right now i need 18x SSD1306 in my project, but the wiki is a bit rare about how to connect the displays from there - I would expand a "how to connect Oleds to the board" if you explain it to me. thx! -mike

Made a wiki Euro-Midi-IO Frontpanel and PCBs are ordered -l now wait for the prototype can someone check the shematic - i may overlooked something: Thx.

this time with the Matias-Switches known from the Midiphy Projects. And the Acrylic Frontplate made by formulor.

@monokinetic I have ordered 5 Boards. 4 I need. 1 then left (1 board is for one LRE8x2) --- if you need more - or you are not in the EU, you know where to find the gerbers ;) and where to get the real cheap, but i suggest to wait untill i testet them. still waiting for the PCBs (10-12 to ship...) - so 2 weeks or so there will be an update - if everything is right... but i got the Acrylic Frontplate, and it fits for the LRE8x2... but the mounting holes for it are not necessery - because the Encoders hold the PCB so the End version of the plate will not have this Holes. the Alps (SIDstyle) Buttons hold nice, and the travel for the inbuilt encoder-buttons are working - so there is no need to remove the Encoders "Noses" I have made a huge eurorack, so no space problems there... and of course the Panel fits (i let some Air for production)
