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 :)
