Add support for RealTime messages

[paradajz]

In MIDI, there are single-byte real-time commands such as Play (0xFA), Stop (0xFC), Clock (0xF8) etc.. See here. What I don't understand why are there single-byte Start/Stop commands and SysEx-like Play/Stop MMC commands. At the moment, only MMC messages are supported in OpenDeck, but whatever, I'll add support to map buttons to those single-byte commands as well later today.

[Momecmusic]

Cool, thank you.

Well, I don't really understand it either and the documentation on this from Elektron's side is non-existent.

You are the man!

OK so here's the updated firmware (beta - I can't test it right now):

Also make sure to clean your Chrome cache since I've updated WebUI as well.

Yes! It works. Have not testet every function of the new firmware, but the real time functions are there and working and I expect everything else to be fine as well.

Once again I can not express my gratitude, I am a very happy customer.

I am expecting the last parts to arrive tomorrow and will shoot some photos for you of my setup this week or early next week.

You can close this ticket now, I have no further requests :)

Great. Also, between this version and last one, I've added support for 7-bit and 14-bit NRPN, so you can test that as well if you need it.

[paradajz]

Additional fix: Added real-time messages weren't sent correctly using USB interface. Referenced commit:
shanteacontrols/midi-lib@d533c0d

Also, make sure to download FLASH.bin again - I've sent you firmware compiled for older revision of OpenDeck board which I'm using for development. That board has different analog component mapping, so make sure you update the firmware (in web interface, board version should be 1.2.0).

[Momecmusic]

Ok, thanks Igor.

Don't think I will need NRPN personally, but it is great to have that option. As far as I understand it, NRPN is more data heavy? So it will be slower? Or are there any benefits I am missing?

[Momecmusic]

Hi again,

web interface says that board version is 1.4 now.

[paradajz]

Can you screenshot this please?

[Momecmusic]

Of course:

[paradajz]

Weird. I'll take a look at it.

[paradajz]

Regarding NRPN, the point is so have more than 127 CC messages, and also to allow 14-bit values for those same CC messages. Standard CC message is one byte long, 7-bit NRPN is 3 bytes and 14-bit NRPN is 4 bytes, so yes, it involves more traffic. You can take a look at it here:

[Momecmusic]

Arh, of course, thanks. Hmmm, might play around with it a bit to see what works best.

[paradajz]

Web UI should now report hw/sw info correctly (if firmware is updated to v1.5.0).

[Momecmusic]

Thanks,

not sure I have v1.5.0 though. Still says 1.4 in the Web UI, and I can only find v1.2 available (By clicking "Check for updates) link in Web UI

[paradajz]

Have you cleared your cache? This is how it looks here:

Checking for release should work fine as well, v1.5.0 is latest:
https://github.com/paradajz/OpenDeck/releases

[paradajz]

BTW, v1.2.0 inside release archive is not firmware version, but hardware version. Since you have board v1.2.0, you need file in bin/compiled/board/opendeck/v1.2.0/FLASH.bin. That's firmware v1.5.0

[Momecmusic]

Yes,

I cleared my cache.

Just now when I went to the Web UI I am experiencing some issues.

Midi page is blank, and it reports "ERROR INDEX" in the activity section.

The other pages work, and I can program the board, but when I click in Info, it just stalls at "Searching for OpenDeck board".

I have sent you an email - let's continue this discussion there as it isn't related to this ticket.
