Headless Mode in Rack v2

According to this thread

@Vortico, is there any more information you can provide about how you plan to implement headless mode?

It will be very simple. Run ./Rack -h to launch in headless mode. No window will be opened, and the autosave.vcv patch will be loaded, or run ./Rack <patch file> to load a patch. You’ll hear sound if the audio interface is set correctly, and you’ll be able to use MIDI-Map and other MIDI modules to control parameters.

That solves the module browser caching problem too! :joy:

(Sorry, I’ll get my coat…)

You won’t be able to add modules in headless mode.

Sounds excellent. Thanks for the info and good luck developing this and all the other new features and modules!

Exactly!

Is there a rough timeline when the v2-branch will be made public?

Around January.

Will Rack v2’s headless mode work on a machine without a (decent) graphics card?

Yes. No OS windowing or OpenGL functions are called. Should work on embedded systems with no video card at all, although libGL is required to be installed on Linux because the Rack binary links to it.

You are my hero! :smiley:

Hello, and thanks for this great soft! Sorry i’m newbie. I’m on mac and looking for this headless mode for less ressources.
i just opened my terminal and copy ./Rack -h it doesn’t run, do i have to put that somewhere else?

Headless mode will only be available from Rack v2, it’s not implemented yet

Ok thanks :slight_smile: happy to try it soon
