    Is this a midibox?

    What is the point when most of the parameters are already accessible on the synth? This makes sense on a Juno alpha for exemple but a 106 !?
    >understood! It's for the virtual one

    The picture is too small but anyway if you did this your-self... Well done! :)

    The LEDs are indeed super bright (~250 - 1000 mcd for the various colours). However, in the setup how I would like to design it, I would use only 4 multiplexed channels instead of your 32, so they would be approx. 8x as bright. Did I deduce that correctly? (I assume the duty cycle of each LED is 1/32 at the most because of multiplexing - or do I misinterpret they way your setup works?). That would mean that I can use LEDs that are 8x less bright than yours to achieve the same physical brightness (while the max duty cycle would be 1/4 in my case).

    Yes, the number of mux lines is settable in the TLC, it will adapt its addressing cycle and memory use depending on that value. There's a resistor connected to TLC which has to be cosen depending on your led, and a lot of registers for color balance, luma, ghosting etc...

    The PMMA mask is very cool! Did you create these yourselves? If so, with which method? (3d printing, molding, etc.). Again - only if you would divulge this information!
    In total - I would be very proud of myself if - at some point in the future - I would be able to achieve something remotely as cool as what you did :)

    Homemade with my cheap and chinese CNC router, bit is 0.8mm 1 tooth alu and I use water+soap to help milling(this is the trick).
    I use black pmma for mask and translucent white for led is a trotec product

    1. It's PEC16-4015F-S0024 . some more information in the dokuwiki...
    2. Yes it's better in real, always difficult to take picture of RGB stuff with an iPhone ;) Brightness is enough for my taste even with the plastic mask and window, the window is made with special pmma,
      led were ordered form china, i can share contact, here the datasheet

    3. Yes I did it manually, it's an ant work.
    4. No update for the moment.
    5. No schematic shared for the moment too! ;)

      Best regards

    @latigid on One day we will have to work on a small and cheap fpga solution to reduce the matricing components and avoid ghosting in the same time ;)
    especially since I've already worked on it for the OLRE16, this work must not be lost...
