OUT NOW · 10 OCTOBER 2026

The sound
comes first.

Two months of work on one thing: making patches play clean, on phones that have little in common. Plus a few comforts that were missing.

The Violet theme, and the new Cream theme.

Audio

The engine tunes itself

Open a patch and RackDroid chooses how many cores to use, for that phone and that patch. Then it remembers: next time it starts at once.

The Threads menu is gone, because there is nothing left to set by hand. The thin bar under the menus shows how hard the engine is working.

In parallel

More instruments, more cores

Groups of modules with no cable between them (several voices, several instruments in one rack) are each computed on a core of their own.

A rack made of separate parts holds far more than before. And it sounds exactly as it did: who does the work changes, the result does not.

No guessing

It tells you when it is too much

When a patch asks for more than the phone can give, the app says so and offers to halve the engine's sample rate.

One tap, and the patch that crackled plays again.

Audio block

Automatic, or your way

The Engine menu lets you choose the audio block size. On Automatic the app looks after it; fix one, and it stays.

Sound

The same edges as on desktop

Square and saw waves now have the shape they have in VCV Rack on a computer. On a phone they were being computed slightly differently.

A patch made on the computer opens on the phone, and the other way round, and sounds the same.

Themes

There is light, too

Beside the four dark themes comes Cream: off-white panels, a pale rack, dark knobs. Pick it from the palette button.

File

Save where you like

File ▸ Save to device opens the system picker: the patch lands in the folder you choose, ready to copy or share.

Mouse

A mouse changes everything

Right button for the context menu, wheel to scroll, zoom and turn knobs, tooltips on hover. On a tablet or a Chromebook you work as you would at a computer.

In short

Everything that changes in 0.1.3

What is new and what is fixed, as a list: so you decide whether and when to update.

New

  • The engine chooses how many cores to use and remembers it for each patch
  • Independent parts of a patch run in parallel, each on a core of its own
  • A notice when a patch is too heavy, offering to halve the sample rate
  • Engine ▸ Audio block: automatic, or fixed by you
  • The engine's load shown on the toolbar
  • Square and saw waves with the same edges as VCV Rack on a computer
  • A light theme, Cream
  • File ▸ Save to device
  • Mouse: right button, wheel, tooltips on hover
  • Smoother pinch zoom and a faster start

Fixes

  • Audio crackling on several phones, even with light patches
  • Crackling that went on after unlocking the screen or under the notification shade: it is now over in about a second
  • A patch could be lost if the app was closed while starting
  • The rack could start scrolling by itself after a drag
  • A menu could stay open and look like a frozen app
  • Opening a heavy patch could hang the app for over a minute
  • Recording started even with no audio output and wrote an empty file
  • The language chosen in Help ▸ Language did not apply to the whole app
  • A large patch was drawn one panel at a time, now within seconds
  • Labels hard to read and misshapen on the light theme
  • Several rare crashes
