Projects and Export

Save your work as projects and kits, back up your settings, and export finished songs or individual stems as audio files.

Projects

A project is everything: pads, samples, synths, effects, sequences, song, mixer and notes.

How to save

The Chop menu

Each project is saved in its own folder (with its samples and cover picture). Saving again skips samples that haven't changed, so re-saves are quick.

Save As

SAVE AS Chop menu > SAVE AS opens BROWSE > PROJECTS BROWSE > PROJECTS with the name box ready. Type a new name and tap SAVE SAVE.

Open a project

  1. OPEN PROJECT Chop menu > OPEN PROJECT (or BROWSE > PROJECTS).
  2. Tap a project and confirm LOAD PROJECT? with APPLY. This replaces your current pads and sequences.
Load project confirmation
Projects page

IMPORT copies a .chop project file into your project folder.

New project

NEW Chop menu > NEW clears all pads and starts fresh. It warns you about unsaved changes, and offers to save on the way out:

Exit confirmation
Save and exit

Autosave

Chop also saves your session automatically in the background, so if Android closes the app, your work comes back when you reopen it. This is separate from saving a project, so still save your projects.

Kits

A kit is a set of pads (sounds and settings) you can load into any project. Save and load kits from BROWSE > KITS BROWSE > KITS (or OPEN KIT Chop menu > OPEN KIT). See Browse.

Backups

In Settings > FILE MANAGEMENT > BACKUP:

Exporting a song

EXPORT SONG dialog

How to export

  1. Name your song and add at least one sequence to it in the SONG tab. See Song Mode.
  2. Chop menu > EXPORT (or EXPORT EXPORT on the SONG tab).
  3. Set the options and tap EXPORT EXPORT.
  4. Choose where to save the file.

Options

OptionChoices
START BAR / END BARWhich part of the song to render.
TAIL (s)Extra seconds at the end for reverb and delay tails (0 to 30; default 1).
FORMATWAV, AIFF, MP3, FLAC, OGG
BIT DEPTH8, 12, 16, 24 (default), 32F. 8 and 12 give a lo-fi crunch. FLAC goes up to 24. Bit depth doesn't apply to MP3 and OGG.
SAMPLE RATE (kHz)22.05, 44.1, 48 (default), 88.2, 96
ANTI-ALIAS FILTERShown at 22.05 and 44.1. On gives a clean result; off gives raw lo-fi aliasing on purpose.

MP3 is saved at 320 kbps. The export renders faster than real time and includes everything you hear: effects, buses, master, mixer settings and automation.

Exporting stems

Render pads to separate audio files (for mixing in another app, or for sharing with a collaborator).

EXPORT STEMS dialog
  1. Tap the export stems icon Export stems (top-left of SEQ or the song arranger).
  2. SOURCE: SEQUENCE (pick which one) or SONG.
  3. Pick pads, or tap ALL USED. GROUPS turns each fader group into one combined stem.
  4. Set FORMAT, BIT DEPTH, SAMPLE RATE, TAIL (s) and MASTER FX: ON / OFF.
  5. Tap EXPORT and choose a folder. Chop makes a "stems" folder with one file per stem (named like A01 or GROUP1).

Exporting from a sequence and from the whole song look slightly different:

Stems from the song
Stems from the song, options

TO PADS puts the stems back onto pads instead of saving files: tap pads in order (or FILL EMPTY BANK), then PLACE.

Pads with no notes are skipped. Exporting stems is free; it's different from the premium Stem Separation, which splits a finished song into parts (see Sampling and Editing).

Exporting a single sample

BROWSE > MEMORY, select the sample, tap EXPORT. If it has slices, choose WITH SLICES to include the slice markers.

Exporting MIDI

See MIDI.
