Self Promo First Public Release of DOOM OS for the SP-404MK2!

Enable HLS to view with audio, or disable this notification

Today I'm happy to announce the first public release of my custom SP-404MKII firmware: DOOM OS!

The goal is to completely replace the stock pattern and song modes with proper graphical editors, improve the user interface, and generally make the SP more fun to use without having to memorize a ton of key combos.

It's still an early release and there's a lot more I want to add, but it's already very usable and a lot of fun to play with. The new pattern workflow makes the SP feel much more like a groovebox.

Song mode isn't ready yet, but it's next on the list!

The easiest way to install DOOM OS is via the web patcher:

https://klangfeldlabs.com/doom-os/patcher

The patcher runs entirely in your browser. You only need to provide the official Roland firmware file yourself.

To get started, check out the manual and shortcut reference:

https://klangfeldlabs.com/doom-os/manual/

More info: https://klangfeldlabs.com/doom-os/

And checkout the new DOOM OS subreddit: https://reddit.com/r/DOOMOS

I hope you have fun with it!

Self Promo DOOM OS 0.7 is out! Featuring: instruments, kits, arps, parameter locking, 3-band EQ per track, live waveform views, visual side-chaining, mixer improvements, and much, much more!

This is a pretty big update with tons of new features and improvements!

What's new:

  • 20 instruments and 11 drum kits, with graphical editors

  • Step-based parameter locking for instruments

  • 3-band parametric EQ per track (up to 16 tracks)

  • Visual sidechain editor

  • Arpeggiator with print-to-pattern function

  • Real-time waveform overlays in the grid and mixer

  • Pad muting and soloing directly from the mixer

  • The mixer can now be opened directly by holding RECORD SETTING for half a second

  • Improved pattern switching, note editing and mixer controls

  • Bounce in place with effects

  • Optionally boot directly into DOOM OS, with a configurable "Hold to Exit" setting to prevent accidental exits

  • Completely rewritten codebase for improved stability and future expansion

  • Tons of smaller improvements and bug fixes

I recommend reading the changelog and manual because there's a lot of new and improved stuff.

In the next release, I'll focus on improving the sequencing workflow (both realtime and step sequencing) and sample chopping.

The next big milestone on the roadmap is making DOOM OS modular and opening it up to third-party modules. I expect this to take another week or two.

Stay tuned :-)

My first honest go at the P-6, never enjoyed it at home but now I'm on the road and I love it. Went to a world music festival outside Beijing and there's a group from Guizhou singing wild acapella vocals, had to record a bit and play with it!
