    I know, but is is just for sales, and does not hold any User-generated content.
    I think forums (or something alike) would benefit everyone involved...

    Default non-working preset storage deselect

    Remember, that little screen isn't super high res. If you do manage to redirect it to an external display, it's either going to stay tiny or get super chunky.

    Thanks for the heads up on the presets. I haven't noticed that issue. Can you prepare a little video and mail it to us so we can see exactly what's happening? Are you sure it's skipping an entire module or just some phase data in that module?

    I'd love to see some photos / video of your setup with the scope

    We're not currently looking for international distributors, but I appreciate your offer and will keep it in mind.
    The Oscilloscope is at my brothers place, and because of lockdown it might be a while until I get there again.

    But I finally arrived at doing a small video showing that even deselected radiator items get stored in a preset.

    Less important, but maybe helpful:
    I found out, if you change a preset's "save_flags=255" field in the .shw file to some other binary value, and load that show file again, you can kind of "limit" what can be stored in that preset...
    The little coloured squares under the preview picture correspond nicely to the binary value, but even when I set "save_flags=1" (only colour should be saved), SOME other elements of radiator react to the values in the preset. so far, I could not find out a pattern.

    Could you maybe include a confirmation message that a show file has been successfully stored to USB?
    I didn't see any hint...

    two radiators are more fun than one, but i could use another set of hands.

    suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

    Default New Presets File (2021/03/06)

    Hey folks, here's a little something we've been working on for a while. It's a new and improved presets file. This is a collection of the previous presets (some re-worked) and a bunch of new presets.

    Presets 221-230 are audio reactive.

    Please dissect, reverse engineer, trade, and modify 😉

    These were made on a 30k projector with Pangolin 506 galvos. If you're using a projector with slower galvos, such as a Lasercube, you'll want to adjust presets that either use high frequencies on the shape generators or ramp / square waves on the LFOs with a high frequency.

    Watch the projection angle and size. If the images display poorly or corners that should be sharp are rounded, or if the galvos make high angry sounds then reduce the speed of the shape generators and / or LFOs.

    Please be kind to your galvos. They are delicate things and we cannot be responsible for how you treat them.

    Remove the .txt suffix on this file before uploading it to the Radiator. See for manual for more information.

    Enjoy!

    Very cool tutorial, very well done and it provides a far better understanding of the versatility of Radiator and how setting up a preset can be done.

    Good idea that tutorial; i would like a tutorial for the CV input,but another tutorial is perfect for me. It's hard when you are neophyte.

    Default bash Script (for OSX & Linux) to trigger next preset on every run...

    Hello, I made a bash script, that, when executed, selects the next preset from a list, and drives the radiator via MIDI.
    On every invocation of the script, by command line, a cron, launchd or atd system, or even the return code of another script, it will launch the next preset.
    The list is in a text file, and You can reorder, repeat, delete presets, whatever floats your boat...
    The script runs on Linux and OS X, not on Windows( because of https://www.fefe.de/nowindows/ ).
    I thought I 'd share it with you.
    Please feel free to ask, comment, share, etc...


    This is the script, call it as you want, but make it executable!:
    Code:
    #!/bin/bash
    # reads next position from $Pointer, 
    # then outputs the 2 values of that postion in 
    # $scene to a RADIATOR connected via MIDI.
    #
    # uses sendmidi   (https://github.com/gbevin/SendMIDI)
    #
    # Files:
    # this Script     (obviously)
    # pointer.txt:    Text file holding the next line to display on the radiator
    # scene.txt    :    Text file holding the 10 Banks with 100 Presets each
    #                first line: number of valid presets in the file
    #                 all other : X[tabulator]YY
    #                where X: Bank(0-9) and YY:Preset (0-99)
    
    
    # set this to YOUR directory of choice!
    workdir="/Users/dirk/"
    sendmidi="/usr/local/bin/sendmidi"          # sendmidi path
    # file holding pointer to next line to read:
    pointer=$workdir"pointer.txt"            # path to file pointer.txt  in workdir
    
    
    # file holding banks and programs:
    scene=$workdir"scene.txt"            # path to file scene.txt in workdir
    
    
    # output device: put YOUR device here
    dev="Protokol"                      # https://hexler.net/products/protokol
    #dev="USB2.0-MIDI Anschluss 2"
    #dev="Unitor8/AMT8 Port 1"
    
    
    read -r linecnt < $pointer
    read -r max_count < <(sed "1!d; q" $scene)
    # echo " max_count: $max_count  linecnt: $linecnt "
    read -r bank_change program_change < <(sed "$linecnt!d; q" $scene)
    # echo "bank_change: $bank_change program_change: $program_change"
    # this is where the magic happens:
    $sendmidi dev $dev cc 32 "$bank_change" PC "$program_change"     # use sendmidi variable to execute /usr/local/bin/sendmmidi
    if [ $linecnt -gt $max_count ]         # restart from beginning    
    then 
    let linecnt=1
    fi
    echo $((linecnt + 1)) > $pointer       # set pointerfile to next entry
    this is the pointer file pointer.txt
    Code:
    2
    this is the (lengthy) scene.txt file( I mentioned all possible 1000 presets, the first line specifies the line where it will restart at the beginning)
    Code:
