The Sample Editor

The Sample Editor is where you shape a single pad in depth: trim its playback range, dial in granular clouds, and audition the result. Everything here applies to the one pad you opened it from.

Opening the editor

Select a pad on the Pad Grid, then tap Edit in the pad toolbar. The editor opens as a full-screen screen showing that pad’s sample. If the pad has no sample yet, load one first by recording from the mic or importing audio.

The title bar reads PAD n — name, and a status strip below it shows the sample duration and the current granular Position as a percentage. A small play/stop button sits in the top-left corner; Done in the top-right closes the editor.

The header

Below the tabs is the identity row: a coloured PAD n badge, an inline name field (tap to rename), and a row of colour chips to recolour the pad. Renaming and recolouring here updates the pad everywhere it appears.

The mode tabs

A segmented bar switches between four sections. The active tab also sets what the play button auditions, so you always hear what you are editing.

Tab	What it shows	Tier
LINEAR	Standard playback properties: mix, output routing, pitch, loop/reverse, playback range, and the linear ADSR envelope	Free
GRAN	The waveform, grain knobs, the granular envelope, and grain options	Free
LFO	The granular LFO — source shape and modulation destinations	Pro
ENV	The modulation envelope — ADSR source and destinations	Pro

The GRAN tab carries an ON badge when granular is enabled for the pad. LFO and ENV are part of the modulation matrix and require GranSample Pro; on the free tier their controls show dimmed beneath an UNLOCK pill so you can preview what they do.

LINEAR: playback range and properties

The LINEAR tab hosts the standard per-pad properties. Most are covered in Linear Playback, but two are central to editing the sample itself:

• PLAYBACK RANGE shows an interactive waveform strip. Drag the handles to trim the start and end, hold the middle to slide the whole selection, drag outside the selection to reselect, and double-tap to reset. A RESET button appears once you have trimmed away from the full range.
• ENVELOPE is the linear-path ADSR (Attack, Decay, Sustain, Release), edited via a draggable chart with sliders below for precise times. This ADSR is Pro-gated; free users see it dimmed with a paywall tap.

GRAN: the waveform and grain region

The GRAN tab opens with the full waveform. Overlaid on it is the grain region — a marker showing where grains are drawn from, sized by the grain window and widened by spray. Tap or drag on the waveform to move the granular Position.

Below the waveform are the grain knobs — Size, Density, Pitch, Spray, Pch Jit, and Spread — followed by the granular Envelope chart and grain options (Window Shape, Reverse Grains, Freeze, and Clear Sample). A further block of musical controls (Pitch Scale, Size Jit, Rate Jit, Prob) is Pro-only. For the full parameter reference and ranges, see Granular Parameters and The Granular Envelope.

If granular is off for the pad, the section dims and offers an Enable GRAN button. If Chromatic Mode is on, granular is blocked until you turn chromatic off.

Previewing

The play/stop button auditions the pad. Because preview follows the active tab, LINEAR plays the trimmed linear sample while GRAN, LFO, and ENV all play the granular voice. Switching tabs while previewing re-renders the preview in the new mode. Tap Done to stop preview and close the editor.

CHOP (Pro)

The CHOP button in the header slices the sample across multiple pads. It is a Pro feature; free users tapping it see the paywall. See Chopping a Sample for the full workflow.

iPhone vs iPad

On iPhone, the editor is the full-screen tabbed screen described above. On iPad landscape, the same LINEAR / GRAN / LFO / ENV controls live in a properties panel pinned to the right of the pad grid, so you can tweak a pad without leaving the performance surface.
