Default Problem programming MD24

John,


Apparently, I successfully programmed the 1.4 firmware update to the MD24. Jeff, another member of this forum, seemed to think so in a previous post in this thread. The MD24 boots up normally with the correct default program after the update.

The problem that I am having is that I can't seem to program my own sysex file even though I am using the same hardware and software setup (USB doggle, computer, MD24 module and Bome's SendSX) that I program the 1.4 update with. Every time I try to program the MD24 with my own file I get the flashing red ACT and STBY lights that I described in a previous post in this thread.

The only reason I can think of why this is so, is that the data in my sysex file has an error. You said that you successfully programed my file after removing the line breaks, but that was from a listed file that had line breaks. The file that I am using is either one that was typed directly into Bome's SendSX "Midi Out" window or a text file that I copied and pasted into the same window and then saved and reopened. Both files had the same appearence in the "Midi Out" window when I tried to program them; a line of 2characters separated by a space. Is this the correct way to enter data into Bome's SendSX?

Would someone please provide me with a sysex file, that I could open directly into Bome's SendSX, that they have successfully programmed. This way I could be sure that the data was entered correctly.

Thanks,

Jeffrey

If the MD24 activity LED continuously flashes at power-up, it means
that the MD24 firmware update was incomplete and the MD24 refuses to
boot up. (It performs a checksum at power-up.)

Is that the LED behavior that you are observing? If so, then you must
try to repeat the firmware update procedure until success.

Firmware update can be tricky, some of my USB MIDI interfaces must be
freshly plugged in to be able to transmit the long message correctly.
It might take some time experimenting.

I did indeed get your sysex to work, but as I mentioned in the thread,
I had to remove line breaks from the message in the SendSX window.

Yes, we can do that. But first, please let me know what the status is
regarding the firmware upgrade. (For your two working MD24s, did you
upgrade the firmware?)

By the way, there is no reason not to continue the conversation in the
forum thread. It's easier to keep all of the information in one
place.

I'm sure we'll get to the bottom of things. Thanks for your patience.

John

Hi Jeffrey,

Is there a chance that you still have the PRGM 0 terminal grounded when you are trying to send your configuration sysex?

That would explain the continuous LED flashing.

If you have PRGM 0 connected to ground, the MD24 will expect a firmware update sysex message. Anything else (including a configuration sysex message) will be interpreted as a problematic firmware update attempt. The flashing LED indicates a bad firmware update message.

When sending a configuration sysex message, be sure that the PRGM 0 terminal is not connected to anything.

Does that solve the problem?

Default Problem programming MD24

John,

Yes, the problem was that I still had PRGM 0 terminal grounded while trying to program a SysEX.

Now that that is solved let me say that the MD24 is a great piece of hardware. I really like it and it is almost perfect for my application. You did a wonderful job designing, building and programming it. I have worked with other units that were not nearly as good. You previously said you were working to improve it. Do you know when the new units will be available and are you planning to restock any of the old ones?

I would really like to see a firmware update that would allow each output to be programmed to a different pulse length.


Jeffrey

Hi Jeffrey,

Thank you for posting the follow-up message. I'm really glad to hear that you got things working.

Thank you for the kind feedback! I don't have a release date yet for the next iteration of the product, sorry. There is no current plan to restock the Rev G MD24. I have noted your feature request.
