    Hello.

    Is it possible to replicate my N1 screen in the Crtlr’s LCD?

    For Capturing LCD this is the Sysex: f042 30 4c 1f f7

    I’ll leave the manual here, just in case:

    Thanks in advance.

    Is all the information of the lcd being sent with a dump? If yes then it should be possible with a lua script.

    Could you add the portion of the lcd dump with the corresponding text on the display?

    Thanks, for you interest.

    I’ve attached in the original message above a pdf with the tech manual.

    But for speed up, I’m sending a piece of that manual with the instructions I believe are the correct ones.

    Thanks in advance.

    Cheers.

    In your picture it shows how you can request a dump for the display.

    The display is 144×40 = 5760 pixels. One position (000h to 2cfh) is 8 bits. So, 5760 dots divided by 8 bits should give you 180 bytes of data. So far so good. But I need a dump to figure out how a pixel is defined in those 8 bits. So if you would be so kind to copy the outcome of the following request: f0 42 30 4c 1f f7.. with a screenshot attached of the display at the moment you do that request. Should make life a lot easier.

    Also, did you see page 9 of the manual under “display”?

    Hello. Sorry for my small understand. 🙂

    Step by step, I’ll achieve it!

    Well I don’t know, but the dump doesn’t seems a lot. If I am doing something wrong, please let know.

    In the sysex it says “3n”, the n is the channel at which the sysex is being sent. Try different channels. Like 30 or 31, 32.. just as long until you receive a long sysex.

    Well, maybe there is another way…

    I’ll take a closer look.

    Maybe that’s a request and then we should send another message?

    No.. it’s a reply that the lcd dump has been sent as a confirmation. Hence the “reply message”. Silly me..

    I’ll get back to it..

    Do you know how to do a total dump of all parameters? Might be the readout of the lcd is somewhere in that dump?

    Hello.

    A few suggestions below. I don’t have an N1. I only read the manuals.
    On the N1, there are some keyboard menu items that need to be manually set/cleared in order to get MIDI sysex messages in/out of N1.

    Can you verify the setting under the Global Mode menu. This is shown on page 65 of the User Manual. “EXCL” should not have an X. The N1 does not respond to sysex messages if EXCL = X.

    At the same time, also check setting under Global Mode menu. Same as above, “EXCL” should not have an X.

    Check the setting under the Utility menu.
    Item: All Prog
    to: MIDI OUT

    From the screen captures, it appears N1 is set to MIDI channel 1 (30).

    As an experiment for the LCD, can you try changing the LCD backlight colour.
    Send sysex:
    F0 42 30 4C 7D 00 F7 this is green colour.
    Maybe use a Uibutton to toggle between the 2 colours.
    F0 42 30 4C 7D 01 F7 this is orange colour.

    If the colour changes, then you know N1 is listening to sysex messages. If the colour does not change, then more investigation is needed to understand why the colour did not change.

    Let us know what happens.

    Thansk a lot, guys.

    I’ll manage that. I’ve used the color switch in my project.

    I made my first version of my panel and upload it. The screen dump is my next step. Thanks for your help.

    You can take a look in here, Maybe you can give me some feedback:
