  1. thanks zener... of course, im preparing for namm and mm, have already 20 units ready to sell... just kidding... the sequenzer is from stagelight and jep, im from ZuReich... best roberto
  2. thanx! at the moment i select the parts by hand with the bank switches... stagelight isn't fully grown yet, there are several things that aren't working. no proper midi assignements, it's not possible to record and playback controller data and so on... so for the moment is cool to jam with it... im working on a max4live interface where things maybe get more easy to do. for example sending controller data to change the banks... also it would be cool to have the parameter names feedback on the GLCD's. OSC or midi exclusive? i havent figured out the best way to do yet... no problem. this is what this forum is for!
  3. yes, the screen is plugged into the internal intel nuc which is hosting the software. the screen is working flawless with win 10. 14 ms response. no luck with osx - there are no decent touchscreen drivers... (shame on bitten off fruits :)
  4. thank you very much master TK! without all YOUR efforts you did the past decades for this platform i couldn't do something like that...
  5. thanks guys. @engineer this is all a question of the software you use. in the video i use stagelight who is capable to host vst's. then there are two moogs controlled also by stagelight and routed back to the software via audio-interface... as example one could use vcvrack (freeware!) as a "touchable" virtual modular synth controlled also with the hardware knobs and encoders... the screen is a planar screen
  6. after 6 months of blood. sweat and tears, 20m of ribbon cable, a ton of parts soldered, screwed and glued - it’s (almost) done! this midibox build-up is intended to use it for what ever i like. it can be a midi controller for music applications, sequenzer, modular controller, video mixer, lightning desk etc… the sky is the limit! still this is a first test controlling some moogs and plug-ins with open lab's stagelight. thanks to the midibox community for the competent help and documentation. SPECS: CPU - Midibox NG on STM32F4, 4 x DIN, 4 x DOUT, AINSER64, AOUT_NG, MIDI IO - Intel NUC 3.5 GHz Dual Core i7, 32 GB RAM SCREEN - 21.5“ capacitive HDMI touchscreen 1920 x 1080 px - 16 x OLED displays 128 x 64 px HARDWARE - 17 x endless encoder with push - 16 x blue LED buttons - 16 x RGB LED buttons - 6 x bank buttons - 4 x function buttons - resistive XY joystick with push - 2 x 60mm faders EXTENSIONS - 8 x CV out - 2 x DIN MIDI I/O - 32 x analog IN (for pots, faders, sensors) - 32 x digital I/O (for encoders, switches, leds) - HDMI port for 2nd monitor, beamer (4K) - 2 x USB3 in ports (NUC) - 1 USB out port (switch for internal/external cpu) - modular voltage out +/- 12v, 5v all the best roberto ps. how to embed YouTube videos? i dort get it... P.P.S: moderator fixed this
  7. oh, cool, many thanks latigid on, as always fast and competent answers! i will try the J10B version, if ist not working then i go with SN74s. thanks for the display driver link, did't saw it ntill now... other question: i do have the alientek OLED's, the dual color version (blue/yellow). now it's displaying in blue... how to change the color? best roberto
  8. Hi i want to extend my project with 16 GLCD's. i found several threads about it but i'm still unsure how to connect the additional CS lines. the first 8 GLCD's work perfect connected to J15A... now i need to know how to connect the other 8 lines. found this wiki where it's stated how to connect additional lines from a J28 named connector. but on a "normal" STM32F4 the J28 isn't available... I read on an other thread that several lines are available on connector J10B. If I look at the schematic J10B is a normal GPIO against the J28 is a audio DAC. Can I use the GPIO's directly as they are to make 8 additional CS lines? if yes, do I need 220 ohm resistors on it? do I need an other boot loader configuration as the one described here in the MBNG manual? if no, how to use a SN74HC595N IC to generate additional lines? Where do i get the clocks (RCK and SCK, Pin 11/12 on 74HC595) and where comes the DISP SER IN (Pin 14 on 74HC595) from? thanks for some enlightenment, roberto
  9. ...just for the record. im slowly slowly get into the deep sea of MIOS... i managed to map the RGB buttons with the multicolour test mentioned in TK's post above. everything's fine... (although magenta is missing in the map, i added it at the end after red...) back to construction
  10. switched back to first comuter, and there it is again... button behaviour inversed again, damned...
  11. strange... i booted the whole thing on a second computer and now it's working as expected... will investigate...
