TECHNO MANIFESTO
Forget toy preset apps. This is the real festival modular engine compiled to set your phone screen on fire.
Raw upstream VCV Rack 2 C++ code untouched. No simplified mobile synth algorithms, just pure DSP horsepower.
Grab jacks, rip cables, perform live drops and build instant sub-bass build-ups straight on your touchscreen.
Oboe + AAudio tuned to the absolute lowest buffer. Drop kicks in perfect sync with the club PA system.
Drop a .rdmod file and Audible Instruments, Valley, Befaco or Bogaudio load instantly. No app update. No store approval. Just drop and patch.
Phones, tablets, Chromebooks, or Android-x86 PCs. If it runs Android 10 or later on arm64-v8a or x86_64, RackDroid is ready to rock.
GPLv3. Every line of source on GitHub. You own it. Run it forever.
WALL OF SOUND
Acid sequencers, screaming filters, and green phosphor CRT scopes reacting live to your patch.
