Subject: [Release] Korg EX-8000 Panel for ctrlrX

Hi everyone,

I am pleased to share my second project made with ctrlrX: a dedicated panel for the Korg EX-8000. It was developed on Linux Mint using ctrlrX 5.6.35 and is fully functional with my hardware.

I wanted to share this to show my gratitude to the open-source community and everyone working on wonderful projects like ctrlrX. Contributing my panels is my way of giving back.

I would like to thank both Damien who continues the development of this project, and "dnaldoog" / John Goodland for his great support that he gave me in my journey of using ctrlrX!

Enjoy the panel!

Best regards, LinuxHRDW

It looks nice. A lot of the warning messages go to console() which no one is going to see. You could create a statusbar type label across the bottom of the panel and print all those messages there instead:
panel:getLabelComponent("statusbar"):setText('Panel synchronized successfully!')

This is an optimized MIDI received code - I haven't tested it though
Also, you released a panel file, which is useless, because there are no resources - you need to export compressed binary and resources .bpanelz file

                -- IMPORTANTE: tostring perché le proprietà sono stringhe
                local customIndex = tostring(sysexOffset + 1)
                local mod = panel:getModulatorWithProperty("modulatorCustomIndex", customIndex)

                if mod ~= nil then

                end

            panel:setProgramState(false)

because there are no resources - you need to export compressed binary and resources .bpanelz file

No resources? lol .... sorry: I was convinced that it was all included in the .panel file...
Try to download again in the first post :-)
thanks again

You have also released it in Panel Edit mode. A user may not realise they have to switch it and immediately decide your panel is broken!

@dnaldoog
Thanks, I got confused. Bear with me. I'll have to be more careful. I set the "panel" mode and exported in .panelz format. (I update the first post)....

Now, I'm asking you kindly:
In your opinion, are there other things I'm missing that I should set up or would this be fine?
Is it also better to export with "panel lock" mode enabled as well?
Does it make sense to include both the .panel and .panelz files when sharing? The .panel file already contains everything needed for other users to use and modify the panel, so why .panelz? What's the difference? I'm a little confused about the two formats...
thanks again

So if you want other people to use your source code, .bpanelz is no different to .panel. It's actually a compressed form of the panel (an xml file) that includes resources, like images and fonts etc. So it would be totally redundant to include both! Panel lock just means if someone is in edit mode, they can move modulators with the mouse, otherwise they have to use keys, but i tend to lock the panel when releasing.

Wow, thanks again for all @dnaldoog, It's much clearer now :)
