pachde (#d) HC-One

I’m pleased to announce that the pachde (#d) HC-One beta release is ready for download and testing on all supported VCV Rack platforms (Windows, Linux, Mac and Mac ARM (M-1)).

HC-One is a plugin with modules for working with Haken Audio’s Eagan Matrix hardware devices. These devices include the Haken Audio Continuum, ContinuuMini, and Eagan Matrix Module (the Eurorack module), and Expressive E’s Osmose. If you don’t have one of these devices, this plugin is not for you.

As you can see from the screen snip, You have instant access to any preset on the device, with the ability to create your own list of favorites, whether they’re custom User presets or System presets. You can save and load different Favorite files, making this suitable for managing set lists for performing with your Continuum or Osmose.

In addition to preset management, there is CV automation of Macros, the Recirculator, and the Master volume (with muting).

I plan to add extender modules for access to most of the functionality of Eagan Matrix devices (except for editing presets). Let me know what settings are the most important for you, so I can build what you need. Some planned future features are noted in the docs.

If you want to know more, read the HC-1 module documentation on github.

You can download the plugin from the pachde HC-One Github Release Page, which also has installation notes, and beta support info.


Hi! I am excited about this plugin and wondering if it is open source? I would love to see it as a part of Cardinal. This way I could use it standalone as a plugin with my Mod Dwarf.:grinning:

The GitHub project is here: pachde-hc-one.

It is currently open under GPL 3. or later, so compatible with Cardinal as far as I understand. I reserve the right to relicense at any time, which might be necessary to fund the work at some point. There is a lot to cover before it’s ready for release, so porting to Cardinal might need to wait until then, but that’s up to Cardinal folks. I don’t know what their process is, and this isn’t the right place for the discussion.

I haven’t tested how well it works in a DAW or other plugin-within-a-plugin scenario. Working with an Eagan Matrix device depends on a direct high-quality bidirectional multichannel MIDI connection to the instrument, which might be difficult to achieve in a DAW or other plugin context. Then again, it may just work ;-).

With all these runtime platforms it takes a lot to get a free plugin ready for release!

The HC One Beta 2 release has arrived!

Now includes the HC-2 and HC-3 modules. For details, see the release page, repo, and documentation.

HC-1 has a lot of functionality built into it. I think I’ve nearly maxed out what’s possible in this module’s form factor. It’s already probably too dense. HC-2 is a WIP. What’s there is solid, but there’s a lot more in the Eagan matrix yet to cover – it is wide and deep. I’m sure there will be more modules than HC-2 once it’s fully built out. HC-3 is essentially complete,
