Thanks for this project.

This is a fork of the original Dexed JUCE plugin that provides Dexed as LV2 plugin. It's a stripped down version which has no own UI and should be used only as a LV2 plugin (e.g. for mod-host).

I would like to run Dexed without a GUI on a Raspberry Pi in an "embedded device" fashion.
Ideally I would just have the Linux kernel running, one process as the LV2 plugin host, which would load and run a couple of instances of dexed.lv2 and output using ALSA (no complicated JACK).

In the meantime, I was trying to run dexed.lv2 in MODEP on Patchbox OS ("Raspberry Pi OS for Audio Projects") because I was assuming this would be easier to start with.

However, it is not entirely clear how to do this?

What I did so far:

  • Using a Raspberry 4 1 GB
  • Downloaded Patchbox OS, unzipped, wrote to SD card
  • Booted Patchbox OS and set it up for the built-in headphones jack (you have to select 44100, 512, 3 - this is the reason I dislike JACK, it always asks techie stuff no one except the devs know)
  • after first booting the system, ran sudo apt update --allow-releaseinfo-change --fix-missing as outlined in their documentation
  • Ran the patchbox utility and installed the MODEP module (I think this is a fancy wrapper around mod-host)
  • As a result, I get MODEP-UI on http://patchbox.local/ (actually I don't want a GUI, in the end I want to configure everything "deterministically" using config files or scripts)
  • Now, how can I get dexed.lv2 to run there?

Would I have to compile it myself on the Raspberry Pi? Or is there a precompiled version available?
Compilation is likely going to fail because the lv2 version needed by dexed.lv2 is no longer in distributions..

How would I load and configure dexed-lv2 in mod-host? Is this possible over the port 5555 with telnet? If so, how?

Hello, i use dexed with Modep in patchbox os.
To get dexed simply go to patchstorage (in the modep gui these is a button on the footer bar9 and search for this plugin. Then press install and it will be downloaded and installed automatically
To use it go to patchbox.local webpage the browse for available plugins in the bottom bar and drag it onto the screen.
Then connect Midi input (on the left) of dexed and the output (on the right) to the out audio port.
If you have a midi keyboard connected you can start playing.
