• Import MIDI:
  • Depending on the file format, one or more clips and tracks may be created.
  • Alternatively, drop a MIDI file from an external app.
• Export:
  • MIDI: export one MIDI file for the clip (you can also drag the clip to another app).
  • Audio: export one rendered WAV file for the clip.
• Delete: remove the clip.

Audio Clips

• Edit: open the audio clip editor.
• Transpose: shift playback one octave up or down.
• Length: change clip length; for imported audio, adjust source BPM and beat count (with optional time-stretch).
• Copy / Paste / Duplicate: reuse clip content quickly.
• Import Audio:
  • Depending on the file format, one or more clips and tracks may be created.
  • You can also drop audio files from external apps.
  • Clips of 20 seconds or less import as Loop; longer clips import as One Shot (play once, without looping).
  • Loop clips are time-stretched to match the project tempo. SAND detects the source BPM:
  • from the file name when it contains bpm (for example 120bpm, 120-bpm, or bpm-128)
  • otherwise by analyzing the audio
  • If the tempo or beat count is wrong, use Length to adjust the source BPM and clip length.
• Export:
  • Audio: exports a rendered WAV of the current clip
  • Original Audio: exports the unprocessed source audio file
• Delete: remove the clip.

Song Mode

Organize your clips into sections that can be launched sequentially. Tap on a section to launch all the clips in it.

Tap the + button on top of the tracks to create a new section.

Add clips to a section by:

• Copying and pasting clips
• Dragging and dropping clips
• Recording directly into an empty clip

Linked Clips

Clips added to a section can be "linked" to the original. Any changes made to one of the linked clips will automatically sync across all linked clips.

Launching Sections

• Tap the section name to launch it.
• All clips in the section will start together.
• The section loops based on its defined length.

Section Options (long press)

• Rename section to keep arrangement labels clear.
• Change section length (in beats). Automatic sets section length to the longest clip.
• Duplicate or delete section to manage arrangement structure.
• Drag and drop to reorder sections in playback order.

Chain Recording

Chain recording lets you record through multiple sections one after another in a single pass, without stopping playback.

To use chain recording:

1. Arm one or more tracks for recording.
2. Select the initial section.
3. Press record. Recording starts on the current section and automatically advances to the next section when the current one completes its loop cycle.

Each section is recorded in sequence until you stop playback or all sections have been recorded. This makes it easy to lay down a full arrangement in one take.

Tip: Set explicit lengths on your sections beforehand so each section records for exactly the intended number of beats before moving on.

Compact Layout

• Tap the vertical handle on the left to collapse a track header.
• If the project has one or more sections, drag the vertical handle on the right to rebalance space between sections and clips.
• Pinch vertically with two fingers to adjust track height.
