  1. Midiloop in my MIDIBox Seq V4

    Hello @Hawkeye, I in fact had the MIDI echo activated on all tracks. The double notes are gone after deactivating the effect. Thanks for your help solving that. Regards Uli
  2. Midiloop in my MIDIBox Seq V4

    Hi Peter, thank you for your quick response. I have just one Blofeld connected to SEQ MIDI out. No MIDI in. I guess that I have set some configuration in the SEQ to loop in the SEQ itself. Best regards Uli PS I'm hearing double notes so I assume a loop.
  3. Hi there, I'm experiencing a midi loop in my MIDIBox Seq. There are no inputs connected and only one synth. Could someone point me to a troubleshooting guide or help me directly? Best regards & thanks Uli
  4. midibox in UV light

    Bad photo by the way. The fluorescent effect of the acrylic color is stronger than on the photo.
  5. And the final SEQ v4+ case! :)

    What a beauty! Looking forward for the kits.

    From the album My #1 MIDIbox SEQ

    Here you can see the engraving of the midibox filled with fluorescent color.
  7. Revised 25-pin breakout port

    Hello there, is someone from Europe able to sell one or better two pair of these boards? Best regards Uli
  8. My second MB-6582 is ready! Sound demo and pics.

    Hey Sciifo, the tune you made with your SID is awesome. Reminds me of "Escape from New York" Filmtrack. Are all Sounds MBSID? (Ok, found the answer on Soundcloud) Thanks for the tune & regards...
  9. RISC-V Platform

    FYI Finally there is an open chip design available. RISC-V developed by Computer Science Division University of California Berkeley. One of the first Dev Boards (a FPGA Board) I'd love to build a MIDIbox project with one of these.
  10. MB SEQ V4 (STM32F4) + BLM + TPD

    I changed in mios32_config.h #define MIOS32_USB_MIDI_NUM_PORTS 8 compiled and uploaded the hex file. But I don't see IIC 5 to 8. Did I miss something? Regards & thanks, Uli I should have changed: #define MIOS32_IIC_MIDI_NUM 8

  12. stm32f4 com led blinking & lcd test issue

    Hi, the problem was due to a missing solder point. Me fool, the hex file came from MIOS8 section. I already have the modified firmware for I²C with 8 MIDI out. Where can I maybe download a compiled version of related Seq application? Regards & cheers, Uli
  13. Hi folks, What does a blinking of the com led mean on stm32f4?When I load lcd interconnection test I get: Hex file contains invalid ranges for MIOS32 STM32!The sequencer app loads fine, I just don't see anything on the display.I had the frontpanel accidentally connected to J10A, don't know if this makes an issue. Thanks and regards, Uli
  14. Hi there, I have no virtualized Windows so I am trying to flash the bootloader with openocd: openocd -f stm32f4discovery.cfg -c "program project.bin exit" I get following output: Open On-Chip Debugger 0.9.0 (2015-11-28-15:54) Licensed under GNU GPL v2 For bug reports, read Info : The selected transport took over low-level target control.

Thanks and best regards, Uli The following seems to work: openocd -f stm32f4discovery.cfg -c "program project.bin exit 0x08000000" At least it doesn't throw an error. But it shows up as "Van Ooijen Technische Informatica". Isn't this weird?
  15. Connecting SD card reader?

    Thanks a lot, was kind of lazy to find it my own.
