  1. So I don't know. Try to change the MIDI channel according to its MIDI manual.
  2. Here is a normal MIDI interface schematic. As you can see ground is only on pin 2 of the MIDI outputs. I think your problem is that the chase bliss has no optocoupler input and doesn't get the signal between the regular pin 4 and 5(between signal and 5V) but between 4 and 2(signal and ground). if no ground is provided on pin 2 of your controller then the pin4(signal) has no reference. Before open the controller check the continuity between midi out pin 2 and another ground, e.g. sleeve of the XPDL jack If there's nothing then open the enclosure and add it...
  3. What is ISO cable? Regular MIDI one? Which plug?
  4. Did you try to receive something from another machine(computer) to the chase bliss with this cable? Maybe pin 2 of your controller is not connected to the ground internally. Pin 2 is a shield and it's normally not used on the receiving side(MIDI In), some manufacturer don't follow the rules and don't connect it. Try with another MIDI Out device, if it works then open your MusicomLab controller and add a piece of wire from a ground position to the pin 2.
  5. Could you show us what you did, cabling pinout and the basic information you got in hand to do it?
  6. This thread talks about how to replace The Empress MIDIbox by a simple cabling. This product is from the Empress brand, and has just the same name as our forum. But! According to the chase bliss documentation, Tip and Ring mus be flipped to use it with the Empress interface. https://static1.squarespace.com/static/5dce1364138bbd66dabfb03c/t/5dd368e2b036cc38a02202ac/1574136034997/Tonal+Recall_MIDI+Manual_Pedal_Chase+Bliss+Audio.pdf I can't try this with my "simple cabling" solution, I've got no chase bliss product. It's maybe your issue. Also trying it is at your own risk ;) Best regar
  7. Hi, By default the UART are configured for regular MIDI DIN speed, 31250 baud. But you can change their configuration, in the mios32_config.h file of your project. The default value(if not previously defined in mios32_config.h) are found in include/mios32/mios32_uart.h // Baudrate of UART first interface #ifndef MIOS32_UART0_BAUDRATE #define MIOS32_UART0_BAUDRATE 31250 #endif Others settings are not easily accessible, they are dependant of the cpu. They are set in mios32_uart.c But they meet your requirement, example for stm32f4xx: USART_InitTypeDef USART_InitStructure;
  8. It's not a robot, just a merchant like the one who comes to your house and knocks on your door or phones you all day(I don't really appreciate them). behind his good intentions, there is a mercantile goal.
  9. This is normal, this is the first startup sequence to init/format the banksticks(eeprom). But it must stop after a short moment. Hummm. Check if it's working with the max-msp manager. or send a whole midi note range over channel 1... Try also to upload this firm: setup_tia_cartridge_keeze.hex If I remember well @Keeze got the same issue.
  10. Eventually send a picture of the board(best reso as you can), I will maybe see something...
  11. Tomorrow check for continuity and short-cut on the UART(MIDI) part of the circuit, mainly between optocoupler and pic, check resistors values, orientation of the diod, check also the orientation of the optocoupler(6N138), change it if possible... here is the diagram, optocoupler is on top-right.... if you have a waveform monitor check the signal on RX path.
  12. Don't worry it can work without ground. but it's molded connector on that side, strange. I maybe didn't connect the right wire color when I did it. but don't touch it let it ike that, it can work without if you don't use 15 meters MIDI cable Can you explain what you did exactly, files used etc... Note: The jumper for MCLR is necessary for Core startup, put it back once you had burnt the pic.
  13. Good pinout is this one: Check if IN pins are not inverted MIDI IN pin4 connected to MI+. DB25 pin14, wire should be green MIDI IN pin5 connected to MI-. DB25 pin1, wire should be white MIDI OUT pin2(center) connected to ground. DB25 pin15 MIDI OUT pin4 connected to MO+. DB25 pin2, wire should be green MIDI OUT pin5 connected to MI-. DB25 pin3, wire should be white There's no specific burner for surface mount, if you've got one you can connect it like this: No it's not destructive, le led are software driven, they their own pic pins. Do you try to
  14. Yes sorry I was on an old dokuwiki revision ;)
