What about a midi driven IOS app?
If Only I knew how to code ios apps

I just stumbled across this thread again because I am thinking of selling my A1. The non-existent clear text display is reason enough for me, although I love the sound and the options. (That's why I wouldn't buy a e.g. a Prophet 6, OB6 or Trigon 6).
I had also thought earlier that it should be possible with a fairly simple iOS app to give a "real" name to the program displayed in each case.

@gitarrenzupfer: Any news or progress about your display?

The display has been working for about 1.5 years now. It's funny that I accidentally checked the forum again a few days ago. I have now made one last code change, as the display hung relatively often after the "studio power-on" and I had to reinsert the SD card. The reason for the problem was that the Nord A1 sent a torrent of midi data when booting, which collided with the SD card data. I have now ordered the display to pause for 4 seconds to wait for the NORD A1 to boot.

@Nordlicht:
I can totally understand people wanting to sell the A1 because it doesn't have a patch name display. This circumstance encouraged me to build the display...

I still have components and circuit boards for another display at home. I'll solder that together when I get a chance.

Hi,

I just read all the thread and would definitely be interested by the project.

Is it somehow possible to buy one of those?
If not, would it be possible to buy the sources (schematic, gerber files, code...) so I can try to replicate on my side?

This seems truly amazing for the A1, really great work of yours.

Hello everyone,

I would like to give a quick update on my display project:

I plan to make some displays (only 3, for more I have to order PCBs) and possibly make some optimizations to the housing. I have also now found a microcontroller with a USB-C connection (instead of the outdated micro-USB).
I can give the displays to interested parties. But I would have to calculate the costs at 100 euros. That's about 50% electronic components + compensation for assembly and development (which took waaaay hours

).

Greetings

P. S. Since yesterday I am also the proud owner of a Nord Wave 2

Again an update on "Project Display":

I'm currently in the process of testing the new USB-C controllers on the board. They run without any problems.

I also made minimal changes to the housing. And I'm currently testing other materials for the housing (PLA, ABS, TPU).
Unfortunately, I can no longer order the neodymium magnets and now have to use a different model (something like this always takes time on the CAD computer).

The (not so pretty looking) housing in the picture is held together with scotch tape and there is also a protective film on the OLED display. In the future I would like to hold the housing shell together with brass drive-in threads.

I have a question for the community

:

If I were to offer a "purchasable version" (although I don't think anyone outside of this forum would be interested) of this display, it would be good/better for the buyer if:

USB-C cable
SD card reader
SD card (actually better if it comes with the software)
5V power supply

or:

None of the accessories are included and the main thing is to be as cheap as possible. Because E.g. everyone has a spare USB-C adapter or an SD card reader lying around at home.

Please share your views with me.

If you are interested in purchasing a display in the near future, please contact me via PM. If necessary, I could also program a Lead 4 variant (the bank/patch structure is slightly different here).

Greetings

Hello everyone,

weekly update (I'm in nerd mode right now). I just designed new circuit boards.

Innovations:

1.
3.5 mm midi socket (standard assignment such as Korg etc...) as the old-fashioned DIN socket was simply too big for the housing and the cable to simply solder on, I found it cumbersome and inflexible if, for example. B. sometimes different lengths are needed or a cable breaks.

2.
Internal DIP switch for future functions:
- Flash mode (software updates by the user)
- Nord LEAD 4 mode
- Other Synth mode (names for 2x 128 sounds e.g.)

3.
I looked around for pretty red USB cables and found them.

Greetings and happy Halloween...

Hello folks,

Project update:

I received the new circuit boards and assembled the first prototypes with USB-C and mini-jack midi sockets (type TRS-A).
I also constantly made small changes in the case design (more internally and because of the connections on the back).
I also printed a red case but the color was just “sucking”. I'm going to get dark gray PLA as I think that goes best with the Nord look.
I'm currently working on additional features that will display the A1's waveforms and OSC configurations when turning the endless pots.
My next task will be a guide or tutorial video that introduces the display and explains the steps on how to load the patch names.

For anyone interested, a few pictures of the latest prototypes...

Best regards from the nerd craft room..

Hi, Happy New Year!!!!

Are you selling this at this moment? I'm very interested.
