@computerscare Thanks that worked perfectly!

Keep in mind that modules used during the headless mode have to have been coded so that they can be run without the GUI. I noticed that for example the Audible Instruments Macro Oscillator 1 (Braids) caused a crash for me in the headless mode. (Tested on Mac Os.)
When will VCV Recorder be available for Rack 2?

Most will probably “just work”? It’s a rare module that goes out and talks directly to the UI.
Probably. I didn’t yet check why exactly the Macro Oscillator 1 module crashed…
I didn’t remember about this discussion, can a moderator move my 2 posts from here? tnx
I tried to run the headless mode on manjaro and it works perfectly!
on my desktop pc it takes ~50% less memory and ~60% less cpu!
I also tried to perform live something via midi and there’s no problem at all 
@Vortico is it possible to create an executable file (pizza.exe or pizza.sh or something else) that saves everything in it? let’s say that I don’t care about the size of the file and the audio goes to the default audio device…
my goal is to run a patch on a server (with no Rack installed) and listen to that patch like a web radio, just knowing the address

me, insomnia, 3 terrifying autogenerative drones playing in 3 rack headless processes…and mixing live (via midi) at 6am
the question is: why did I end up this way? 
[edit]
next level…then you quit

those percentages sound promising for my sonaremin project … i’ll wait a bit until v2 has settled before making it work on arm linux again and i’m looking forward to this real headless mode then

I didn’t try on the win10 laptop. I’m busy next days, I’ll give it a try (I hope) in one week, just to have a comparison, with the same patch

Still very much interested in trying out Sonaremin. Are there currently any limits for the audio interface you connect? Sonaremin + Expert Sleepers es9 would be an incredible addition to any physical eurorack.
i have no idea if it works with es9 or not as i do not have the hardware - it should work more or less with usb audio compliant interfaces … but you never know
Cool. I guess the costs of a sonaremin install aren’t the big drawback…
compared to an es9 most probably not - just avoid the 8gb model for now (2/4gb is fine) … for more on this maybe lets move to the sonaremin topic to not hijack this one here too much …
I made a quick test patch with only core modules. When opened with a full rack window I get sound. when trying to run headless, it seemingly does nothing.

Command line and path: C:\Program Files\VCV\Rack2Free>rack -h “c:\Users\PeterS\Music\test.vcv”
If I do the same command line without the “-h” the patch loads up and sounds correct.
Is this idea dead? Or am I doing something wrong?
Headless mode works fine, but how to exit?
Ctrl-C 
Ctrl-C doesn’t work on Windows.
