DIY OLED Display for NORD LEAD A1

[Elias]

I would definitely be more than happy to pay you some (parts plus some extra) if you ordered parts for numerous units and just shipped them. I'm absolutely ok with soldering and building a case for the screen. If one person can order all the parts in one go, it will be easier and cheaper.

(But let's not get too excited, yet)

EDIT: Maybe a list of parts, the schematics and software shared here would be enough for some, at for least me.

depending on the quantity, the design of a custom PCB would of course be a great thing. The PCBs can be quite easy designed online and received in a very short time (at a price that is worthwhile considering the soldering time)

Hello NORD-users,

Is there a NORD Lead 4 user who would be so nice and could upload a HTML programlist and the HTML performancelist generated by the NORD Sound Manager?

I saw that the banks are structured differently here than on the NORD Lead A1 (4x 100 instead of 8x50 programs). If I look at that right away, a display version for NORD Lead 4 would be easier to implement if needed (I don't own a Lead 4).

Another interesting question would be whether the HTML export with MAC OS is exactly the same as with Windows (I don't own a MAC either).


Finally I can also report that the patch names can now be imported through a SD card reader attached to the display

Update:

The current 3D case and the expected custom PCB.
I decided to reduce the number of functions and buttons because I just don't really need them and the size of the
Housing would only be unnecessarily enlarged.

Maybe at version 2.0 ...


P.S.: the 6 cube-shaped holes are for 6x6x6 mm neodymium magnets. They hold the plastic housing on the metal housing of the NORD.

Can this be easy modified for the NS2? My NS2 is underneath another board (pretty close to eachother) so I can't read the display very easy. Don't have to because everything is controlled by Bandhelper.
But sometimes it's good to see if the program actually changes or to adjust to another program.

As far as I have seen, the sounds of the NS2 are organized in 4 banks of 100 programs. From this point of view it would be easy to adapt the code, since the NLA1 has 8 banks with 50 programs (also 400).

If you can also do an HTML export with the sound manager on the NS2, it wouldn't be a big deal.

Basically you could use the display for any synth or midi device (every manufacturer), which sends program change commands when switching sounds.

You just have to write the desired patch names in a txt file and copy them to the SD card in the display box. For this conversion from the NORD HTML export to .txt-file I made a libre-office calc-sheet (very rudimentary, but it just works).

Today I received the circuit board from China. I chose red color
Unfortunately I forgot a conductor track (that was my very first PCB design ), but I was able to solve it with an additional cable on the underside.

What annoys me a lot more is that when I re-soldered the header on the 2.42 "display I scrapped it . I used another 0.96" OLED display as a replacement. Very small, not for bad eyes

I will try to revise the PCB so that I can also use displays directly from the manufacturer (currently I have re-soldered it from SPI to I2C - SMD components, not funny).

Hi, everyone,

I finally finished the project (at least until the next version). For me, however, it works as I need it and therefore it will probably stay that way for the time being.

The conversion from I2C to SPI was too cumbersome for me because I would have had to create a new PCB and it takes too long for me. I also have 3 left over from the old PCBs.
I abused the ARP RUN button (double click) to switch between performance and program mode. To switch between list display and normal display, do the same with the HOLD button (double-click).

I made a short video to demonstrate this :

Looks very pro!

Looks great! I’m interested and would love one.

I can help you with streamlining the code into a simpler .exe.

I built a relatively similar python app which managed data to/from a ns2ex ages ago.
