Sample Editor

Renoise has a strong focus on samples as instruments and features a lot of pattern effects to mangle and modify sample playback. To aid with this, there is a built-in Sample Editor to modify and edit samples. New small samples (mostly for short looping wavetable) can also be created, via a simple drawing function.

Any changes made within the Sample Editor are exclusive to the samples within that particular Renoise song. The source samples are never modified unless you explicitly save and overwrite the file by saving it in the Disk Browser. Besides being non-destructive to the sample files, the Sample Editor also supports full and endless undo/redo-ing. Because undo/redo on very large samples can create an unwanted overhead, the undo/redo-ing of samples can be disabled. See below for more information.


Overview

File:Vvoois renoise sample editor.png


The editor is divided into three parts:

  1. The upper bar with the sample name, sample rate, bit-depth on the left and snapping, zoom and draw controls on the right.
  2. The central area showing the waveform with two horizontal rulers along the top and bottom. Here you view the sample that is currently loaded and select what you want to edit.
  3. The lower section featuring the buttons and options used to edit or modify the sample.


Snapping, Zooming, Drawing and Sample Properties

  • File:Vvoois renoise se draw.png - When enabled, you can freely draw on the sample waveform with the mouse. Simply hold down the mouse button and drag to draw. When disabled, the mouse is used to select and scroll the waveform.
  • File:Vvoois renoise se snap20.png - Snapping applies to the waveform when using the mouse to select, using keyboard shortcuts to navigate around in the sample, or when applying and dragging loop points. It can be useful to have "Snap to: 0 Crossing enabled, as this will ensure that cutting and pasting parts of a sample do not produce clicks in the audio, because the start and end points will always match up at 0. Snapping to beats is useful when cutting out beats from loops, in combination with the "Copy to new Instrument" context menu/keyboard shortcut.


Wave View

Upper and Lower Rulers

You can individually set the upper and lower rulers' display measure by right-clicking on them and selecting an option from the context menu:

Lower Zoom Bar

As an alternative to using the mouse or keyboard shortcuts to navigate around in the waveform, you can use the zoom-bar beneath the Lower Ruler to scroll or zoom. Drag the bar in the middle to scroll and drag the handles to extend/shrink the waveform view. Clicking on a free space next to the bar will jump a page in that direction.

Navigate Using the Mouse

  • Left Mouse Button:
    • Single-click sets an offset/cursor position.
    • Click and drag spans an area in the editor.
    • Click and drag with "Shift" extends/shrinks either side of the selection area.
    • Double-click selects the entire visible area of the waveform.
    • Click, drag and moving the cursor outside the wave editor to the left or right will zoom out. Holding down "Control" while doing so will speed up the zooming. Holding down "Shift" while doing so will scroll instead of zoom.
  • Right Mouse Button:
    • Single-click opens a context menu.
    • Click and drag extends/shrinks either side of the selection area (same as left-click and drag with "Shift").
    • Click, drag and moving the cursor outside the wave editor to the left or right will zoom out. Holding down "Control" while doing so will speed up the zooming. Holding down "Shift" while doing so will scroll instead of zoom.
  • Middle Mouse Button:
    • Single-click a point in the sample: Plays the sample from the clicked position to the end of the visible waveform.
    • Click and drag plays the selected are of waveform.
  • Scroll Wheel:
    • Zoom in/out of the waveform view.
    • Hold "Alt" while scrolling to scroll horizontally instead of zooming.

Note that the waveform view will zoom from the position of the mouse pointer. So, to get a closer look-up of a specific area, hold the mouse point over that area and start scrolling with the mouse wheel.

Navigate Using Keyboard Shortcuts

  • Arrow Left/Right: Move cursor to the left/right. In combination with "Shift", a selection is created.
  • Arrow Down/Up: Zoom in/out at the cursor position.
  • Home/End Key: Move cursor to the start/end of the waveform. In combination with "Shift", a selection is created.
  • Enter: Play/restart the sample from cursor position.

Default operations such as Copy/Paste ("Control/Command + C", "Control/Command + V") and so on are available as well.


Processing Buttons and Options

Please Note: Most processing options below that change the sample (like Cut/Copy/Paste or Fading) will either apply on the whole sample, when no selection is set, or will apply on the selection, when a selection is present.

Undo/Redo Support

  • File:Vvoois renoise se trigger undo.png - Enable/disable undo in the sample editor. When working with very large sample, temporarily disabling undo may be useful to save a bit of time. Renoise saves all undo/redo processing on disk, so running out of memory should not be a problem. By default it does not hurt to have undo enabled.

Create / Adjust Sample Properties

When a sample is loaded, you can setup/change basic sample properties, like the amount of channels and sample rate here:

File:Vvoois renoise se sample properties.png

When no sample is loaded, you can create a new sample. This is especially useful to create small looped hand-drawn samples:

Cut/Copy/Paste

Amplitude & Offset

Fading

Reverse & Swap

Process Track FX

  • File:Vvoois renoise se trackfx.png - Apply the current tracks DSP (as set up in the Track DSP tab) on the sample. This way you can apply any of Renoises built in effects or any plugin effects directly to the sample.
  • File:Vvoois renoise se smooth.png - Smooth the sample. A simply interpolation which removes hiss and edges form the sample. Especially useful to smooth hand drawn samples a bit.

Loop Controls

Play/Stop and Record

Current Selection Range Indicator

  • File:Vvoois renoise se offset.png - Next to the record button, the currently set cursor position or selection start and end are shown in the lower rulers format. To change the format, right click on the lower ruler an choose a new format, like samples, minutes or 09 pattern command offsets.


Mix Paste and other Copy/Paste Operations

Mix Paste

Renoise offers a simple mix paste functionality. TO use it simply copy a part or whole sample into the clipboard first, then click on mix paste. A dialog will pops up that offers some options on how to mix the clipboard content with the exiting content:

Copy Into New Sample/Instrument

Via the context menu or keyboard shortcuts you can also automatically copy regions of a sample into either a new sample in the current instrument or a new instrument. This can be very useful if you want to slice up a loop and create a drum kit out of it. Or when copying parts of a large sample for further playback or editing.


Copying/Paste With External Sample Editors (Windows only)

Renoise shares its clipboard content with the system on windows, which means you can quickly swap around sample data from and to Renoise when using an external sample editor which also supports this feature. In many external editors you do have to select/activate this feature some where first. Please have a look into your editors manual, by looking up the keywords: "System Clipboard", "Copy".


Loop Fine Editor

The loop fine editor shows you an exact sample precise overview of the loop start and end points. This is very useful to create smooth loop. Loops should in most cases start and end at the sample amplitude values in the sample to avoid clicks. The Loop fine editor give you an overview of exactly this.
