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

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.

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

Hello there, is someone from Europe able to sell one or better two pair of these boards? Best regards Uli

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...

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.

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

Seem to have successful compiled one on my own. Application successfully built for: Processor: STM32F407VG Family: STM32F4xx Board: STM32F4DISCOVERY LCD: universal Regards

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

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

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 http://openocd.org/doc/doxygen/bugs.html 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?

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

Hi all, I'm not quite sure how to connect an SD card reader to J16 of STM32F4. My reader has: GND3.3VCSMOSIMISOSCLKGND and 3.3V is obvious. I guess MOSI to SO, MISO to SI, the rest I don't know. Thanks in advance, Uli

I just want to brig the Makerarm to your attention. I think this is really awesome. Regards, Uli

That's satifying, thanks. I was crimping some wires and even with a crimping tool I found it really sucks. As I plan to connect my MIDI ports and LEDs via cable, because otherwise I wouldn't have enough space on my backpanel, I would have to crimp about hundred pieces. These really save me some time and stress. Regards, Uli

Hi, is anybody interested to get some of these from Alibaba, a minimum of 4000 is to much for me? I'd need about 500. Or is there any similar cheap supplier with less minimum order? Regards, Uli

Thanks for the qualified answer.

Hi folks, am I right when I guess there is no problem to connect this ENC28J60 Ethernet Module to MBHP_CORE_STM32F4? Regards, Uli
