I finally uploaded applications to the mb-6582 with another MIDI interface. Thanks to everybody :)

I've got some news. I've just read the midi interface blacklist, and effectively my cheap Ebay interface is into it. And now it's sure, it's a midi interface issue. As I never saw any MIDI message on MIDI IN monitors on my PC, I tried on a Mac. Here's the result : I'll try to put my hand on a decent midi interface, and I'll keep you informed. :)

Hello Nils :) About the MIDI routing in Mios Studio, I think my settings are correct. When I put off the PIC1 and put a jumper on J11_CORE1, the MIDI loop between MB-6582 and PC seems ok. I receive in the MiosStudio MIDI In monitor all messages I send with the virtual keyboard. And if I put a PIC while there's a jumper on J11_CORE1, I can monitor lot of "truncated" SysEx requests. If the LED flash during power on must be a SysEx request, in my case it's certainly a non valid MIDI message.

Hello Wilba, All the parts I've got are coming from SmashTV (Hello Tim!!). The PICs are also coming from SmashTV, I received them burned with Mios 1.9f Crystals are 10MHz, they are flat on the PCB, there's not a lead longer than the other. Now about the test of the LED on midi output : I have a very short flash exactly when I switch power on. I insist on the fact that there's no delay between the moment I see the LED flashing and I push the power button. Then two seconds later, the PIC puts the "MIOS V1.9f..." message on the display. Now I remove the LED, and plug the MIDI interface. When I monitor the MIDI output of the MB-6582 with MidiOx during the power on, there's nothing, no message at all. But I'm sure that the power on "LED flash" happens on the MIDI output because my MIDI interface has 3 LEDs on it (usb power, midi in, midi out) and its yellow MIDI In LED flashes the same way (i.e. single short flash) did the LED I used for previous tests. That's all for tonight, I go to bed :)

I confirm you it's normal. There's only backlight power for core 1. :)

First, thank you very much Wilba for this fast answer :) Here the results of the tests : 1st Test As you asked, I took off all pics, put a jump to position 1 of J11 and another one on J11_CORE1 to loop Rx and Tx. I sent some Note On/Note Off using MidiOx and I received them back from the midi out of the MB-6582. 2nd Test I removed the jumper on J11_CORE1, and now when I send some Note On/Note Off, nothing is going out by the midi out of the MB-6582. We can conclude that there's no short. ??? I still wonder what can be wrong :(

Hello everybody :) I reply to this topic because my symptoms are the same. The MB-6582 is staying on "Ready", and that's normal without an application upload. The problem is that I can't upload anything. First I've tried the upload with midistudio, then with midi OX. I noticed that the midi out port of the MB-6582 never outputs anything. Of course I suspected my cheap midi interface to be the source of this, but I was wrong. I tested it with another synthesizer and received my old TX81Z Sysex with success. I also changed the position of the J11 jumper to see if one of the four cores would "say" something. Still nothing on the midi out... I deceided to check the continuity between the pin 25 to the midi out (J12 M-), and I've got a 220ohms resistance. Then I tried something really silly : Doing a shortcut between Rx and Tx by putting a jumper on the J11_CORE headers. And guess what, I receive lots of upload request, exactly as mentionned on Thorsten's Midi Troubleshooting guide. At least I saw something on the Midi In Monitor!! :o Now I'm terribly happy but it still doesn't work. :P I miss something and I haven't got a clue of what. I can understand why I never get anything on outputs of any pic. ??? Any help would be greatly appreciated :) Best regards, Fred

Hi, I've just added one in the list too Thanks again Doug :)
