Skratch Attach

Setup: connect your Rane One

Skratch Attach works with the Rane One MK1 and MK2 out of the box — no mapping files, no configuration wizard.

1. Plug in

Connect the Rane One to your Mac, iPad, or iPhone over USB and launch the app. The device is detected automatically — the app recognizes which model you have (MK1 or MK2) and loads the right profile, lighting the pads and syncing the controls.

The app runs in landscape only on every device, and on a phone it remembers which way you were holding it for next launch.

No controller? See Standalone mode.

2. Audio

The Rane One is the app's audio interface. Skratch Attach configures it at 48 kHz automatically. Check Settings → Audio for:

  • Master gain and headphone gain
  • Metronome volume and which channel carries the click
  • Phono input selection — if you're running control vinyl (DVS), tell the app which inputs your turntables land on, then head to DVS setup

Settings, Audio: the master, headphone-boost and metronome level knobs, the metronome route, and the audio device with its active input and output channels, sample rate and buffer size

3. Your files

There are two Skratch Attach folders, and knowing which is which saves a lot of hunting.

The two Skratch Attach folders: your music library holds your tracks plus Stems, Wax ID Archives and Guests; the app's own folder holds Samples, Loops, SkratchPads, Tapes and UserPresets

Your music library — ~/Music/Skratch Attach on Mac, Documents/Music on iOS:

FolderWhat goes there
(the folder itself)Your tracks. Anything you drop in shows up in the browser
StemsSeparated stems
Wax ID ArchivesThe FLAC archives behind your Wax-IDs
GuestsCrates sent to you by someone else

The app's own folder — Documents/Skratch Attach on Mac, Documents on iOS:

FolderWhat goes there
SamplesOne-shots for the Sampler
LoopsLoop files for the Loop Player
SkratchPadsScratch sounds for DVS bank 1 (the folder keeps the older name)
TapesYour recorded sets
UserPresetsSaved settings presets — Settings → Presets saves and loads them

Settings, Presets: a single card with SAVE PRESET and LOAD USER PRESET buttons

Drop files in with Finder or the Files app and they appear in the app's browsers.
