Sampler Waveform
Waveform
The Waveform editor displays an instrument's samples so you can edit them with the provided tools and see the results graphically. New samples can be recorded directly into the editor from external sources, or created by hand with the simple Draw tool. Any changes made to samples are exclusive to each individual 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, the editor also supports endless undo/redo-ing of all your actions.
The large central section displays the waveform and allows you to select parts of the sound for editing. Loop points and Slice markers are also placed and displayed here. The top section features the sample-type options on the left and the Draw, Slice and Snap controls on the right. Contained within the lower section are the options used to edit or modify the sample and additional options can be found in the right-click context menu.
Working With The Waveform
Upper and Lower Rulers
Directly above and below the waveform are rulers which display various time measures. You can set the measures individually by right-clicking on a ruler and selecting an option from the menu:
File:2.8 sampleeditor-rulers.png
- Left Mouse Button:
- Single-click sets a cursor (edit/play) position.
- Click and drag spans an area in the editor. In a stereo sample, moving the mouse pointer above/below the top/bottom 0dB line will allow you to select the left or right channel only.
- Click and drag with "Left Shift" extends/shrinks either side of the selection area.
- Double-click selects the entire visible area of the waveform.
- Click, drag and move the cursor past the left/right side of the wave editor to select while zooming out. Holding down "Left Ctrl" ("Command" on Mac) while doing so will speed up the zooming.
- Right Mouse Button:
- Single-click opens the context menu.
- Click and drag extends/shrinks either side of the selection area (same as left-click and drag with "Left Shift").
- Click, drag and move the cursor past the left/right side of the wave editor to select while zooming out. Holding down "Left Ctrl" ("Command" on Mac) while doing so will speed up the zooming.
- 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 area of waveform.
- Scroll Wheel:
- Zoom in/out of the waveform. Note that the zooming happens from the position of the mouse pointer.
- Hold "Left Alt" while scrolling to scroll horizontally instead of zooming.
Keyboard Shortcuts
- Arrow Left/Right: Move cursor position to the left/right. In combination with "Left Shift", a selection is created.
- Arrow Down/Up: Move cursor position up/down (in a stereo sample).
- Ctrl/Command + Arrow Down/Up: Zoom in/out at the cursor position.
- PageDown/PageUp: Zoom in/out vertically.
- Home/End Key: Move cursor to the start/end of the waveform. In combination with "Left Shift", a selection is created.
- Enter: Play/restart the sample from cursor position.
Standard operations such as Copy/Paste ("Left Ctrl + C/V") etc. are available as well.
Lower Scroll/Zoom Bar
As an alternative to using the mouse or keyboard shortcuts to navigate around in the waveform, you can use the scrollbar beneath the Lower Ruler to scroll or zoom. Drag the bar to scroll or drag the side handles to zoom. Clicking on a free space next to the scrollbar will jump to the immediate left or right of the waveform's current location. Just to the right of the scollbar are extra zooming controls:
- File:2.8 sampleeditor-zoomout.png - View full sample (zoom back out to show the whole sample, horizontally and vertically).
- File:2.8 sampleeditor-zoominv.png - Zoom in one step vertically.
- File:2.8 sampleeditor-zoomoutv.png - Zoom out one step vertically.
Upper Control Bar
Create/Adjust Sample Properties
Located at the top left of the interface. Changes the basic properties of an existing sample or, in a blank sample slot, creates a new sample.
- File:Vvoois renoise se properties.png / File:Vvoois renoise se create.png - Edit sample properties / Create new sample.
Drawing
File:Vvoois renoise se draw.png The Draw button is located at the top right of the interface. Draw mode allows you to draw on the central waveform area with the mouse, where you can create brand new sounds or make adjustments to existing sounds, such as removing clicks.
Slice Markers
The slicing controls are located at the top right of the interface. Slicing allows you to non-destructively split a sample by inserting markers, which can be usefully placed on individual drum hits, notes, vocal phrases etc.
- File:2.7 sample editor slice button.png - Activating the Slice button will change the mouse pointer to the Slice Marker Tool. With this you can left-click on the waveform to slice it into different sections.
- File:2.7 sample editor auto slice button.png - Automatically insert markers into the waveform at points where beats/transients are detected.
- File:2.7 sample editor auto slice peak detection ratio.png - The sensitivity of the auto-slicing beat detection can be adjusted using this value box. Higher values will lead to more markers being inserted.
- File:2.7 sample editor slice termination mode.png - If enabled, a triggered slice will stop playing at start of the next slice.
As you add slices to a sample, the Keyzones editor will automatically lay these out across the keyboard according to its current Drum Kit settings, allowing you to trigger each slice from a different key on the keyboard. You can also trigger a slice via the 0Sxx Pattern Effect Command, where the xx value corresponds to a slice number. Each slice you place is given a numbered tab at the top, and left-click-dragging on it will move the slice around. Right-clicking on a tab will bring up a menu with the option to: select all markers, delete the current marker or delete all markers.
Although you can still edit the original sample, you cannot edit the individual sample slices. However, the Loop type and all Sample Properties like volume, panning etc. can be changed per slice. A newly created slice will inherit the original sample's properties.
To destructively render an instrument's slices into individual samples, right-click on the waveform and select "Slices > Destructively Render Slices" from the menu.
Snapping
The Snap controls are located at the top right of the interface.
File:2.8 sampleeditor-snap.png
Snapping applies to the waveform when selecting with the mouse, using keyboard shortcuts to navigate, and when applying or dragging loop points and slice markers. It can be useful to have "0 Crossing" enabled, as this will ensure that cutting and pasting parts of a sample does not produce clicks in the audio, because the start and end points will always match up at 0dB.
Selecting "0S Effect" will snap to the 0S markers typically shown along the bottom of the waveform, while selecting "Markers" will cause the selection to "stick" to sample slice markers as the mouse pointer approaches them.
Snapping to beats (the length of time for a single beat) is useful when cutting out beats from loops, in combination with the "Copy Into New Instrument" context menu/keyboard shortcut. The other Snap options are smaller fractions of a beat.
Processing Controls and Options
Located underneath the waveform, most of the processing options below will apply to the whole sample unless a specific area has been selected.
Undo/Redo Support
- File:Vvoois renoise se trigger undo.png - Enable/disable undo in the Waveform Editor. When working with very large samples, temporarily disabling undo may be useful to save time. Renoise saves all undo/redo processing on disk, so running out of memory should not be a problem.
Cut/Copy/Paste
- File:2.8 sampleeditor-cut.png - Cut the selection (or whole sample if nothing is selected).
- File:2.8 sampleeditor-crop.png - Crop to selection (delete everything outside of the selection).
Amplitude
- File:2.8 sampleeditor-volume.png - Change the volume of the sample or selection (will open up a dialog to specify the exact amount).
- File:2.8 sampleeditor-maximize.png - Raises the volume of the sample or selection to the maximum possible value without clipping.
- File:2.8 sampleeditor-silence.png - Inserts silence into the selected range, or silences the whole sample if no range is selected.
Fading
- File:2.8 sampleeditor-fadein.png - Fade the sample in linearly (can fade logarithmically via the right-click context menu or shortcuts).
- File:2.8 sampleeditor-fadeout.png - Fade the sample out linearly (can fade logarithmically via the right-click context menu or shortcuts).
Reverse & Swap
- File:2.8 sampleeditor-reverse.png - Reverses the sample or selection.
- File:2.8 sampleeditor-dcoffset.png - Center the sample or selection to the DC line. Fixes vertical DC offsets.
- File:2.8 sampleeditor-invertphase.png - Inverts the phase of the sample or selection.
- File:2.8 sampleeditor-swapchannels.png - Swaps the left and right channels of the sample or selection. Only possible for stereo samples.
Process Track FX
- File:2.8 sampleeditor-fx.png - Apply the current track's DSP effect chain directly to the sample's waveform (applies both native and plugin effects). Note that this will not automatically extend the length of the sample (reverbs, delays etc. last longer than the original sample).
- File:2.8 sampleeditor-smooth.png - Smooths the sample. A simple interpolation process which removes hiss and sharp edges from the waveform. Useful to smooth out hand-drawn samples.
Loop Controls
- File:2.8 sampleeditor-crossfadeloop.png - Automatically creates a smooth cross-faded loop.
- File:2.8 sampleeditor-loopcontinue.png - Toggles whether a sample will finish its current loop after a Note OFF input.
- File:Vvoois renoise se looptype.png - Set the loop type or turn it off.
Play/Stop and Record
- File:Vvoois renoise se play stop.png - Start/Stop playing sample from the cursor position to the end of the visible waveform, or Start/Stop playing the selection if one is present.
- File:2.8 sampleeditor-prehear.png - Select where the sample will be played back: On the Master Track to bypass the current track's effects, or on the selected track to hear the sample with the currently active effects.
- File:2.8 sampleeditor-record.png - Open up the record dialog box, to record new samples from various sources (e.g. microphone, line-in etc.) For further details, see the Recording New Samples section.
- File:Vvoois renoise se offset.png - The current cursor position or selection range positions are shown in the format of the Lower Ruler. To change the format, right-click on the Lower Ruler and choose from the list.
Right-Click Context Menu
Mix-Paste
Renoise offers a simple Mix-Paste functionality. To use it, simply copy a sample or a selection of a sample into the clipboard, then right-click and choose "Mix-Paste". A dialog will appear that offers options for mixing the clipboard content with the existing content:
File:Vvoois renoise se mix paste dialog.png
Copy Into New Sample/Instrument
You can automatically copy a selection of a sample and place it in either the current instrument or a new instrument. Open the right-click context menu and choose "Copy Into New Sample" or "Copy Into New Instrument". This can be very useful when copying parts of a large sample for further playback and editing.
Fade In/Out Logrithmically
This will fade the selection area in/out logrithmically instead of the standard linear process.
Set Loop Start/End
With these options you can insert loop start/end points directly onto the cursor position. If a selection area is present then both the start and end points will be placed to loop that exact range.
??? Loop Fine Editor ???
The Loop Fine Editor shows you a sample-precise overview of the loop start and end points, which is extremely useful for creating smooth loops. In most cases, loops should start and end at the same amplitude value to avoid clicks.
File:2.7 sample editor loop fine editor.png
Copy/Paste With External Sample Editors (Windows only)
On Windows, Renoise shares its clipboard content with the entire system, meaning you can quickly swap around sample data to and from Renoise when using an external sample editor that supports this feature. In many external editors you have to select/activate this feature first. To find out how to do this, please look at the external editor's manual and search for the keywords: "System Clipboard", "Copy".
Recording New Samples
Renoise allows you to create new samples by recording them from various sources, including a line-in jack or microphone. To do so, press the File:Vvoois renoise se record button.png record button located in the Lower Control Bar. Alternatively, you can open the record dialog by choosing, "File->Record New Sample..." from the main menu at the very top left of the interface.
Bringing up the record dialog and controlling the main record options can be mapped to a MIDI Controller with the MIDI Mapping options. This way you can quickly make new recordings using just your MIDI controller or master keyboard. To map the opening and closing of the record panel, switch over to the !!!???###???!!! before pressing the MIDI Map button.
To record new samples in Renoise, first configure the device you want to use for recording, which is done via the "Edit->Preferences->Audio" panel. This is only necessary when using DirectSound (Windows), Core Audio (OSX) or ALSA (Linux). ASIO is pre-configured to be used as a recording and playback source. When your soundcard has more than one input channel, you will be able to set this as the input device in the Audio Preferences, or you can select this in the recording dialog.
Recording Controls
File:Vvoois renoise se recorder.png
This VU meter displays incoming audio activity, allowing you to monitor the signal and make adjustments if necessary. The speaker button enables you to listen to the input through Renoise while recording.
Select which channel you would like to record: left, right or both (stereo).
Select the audio device that will be the source for the recording.
Select the track DSP effect chain (the list displays all tracks in the song) that will be applied to the recording, or just to the the preview of the recording.
File:Vvoois renoise se recorder options.png
- Sync start & stop:
- None - No quantization is applied. Hitting the start/stop button will start/stop recording immediately.
- Pattern - Applies quantization from the start to the end of the current pattern. When the song or pattern plays, recording will be started or stopped only at pattern boundaries or block loops. This is useful to record "live" (e.g. playing a guitar riff along to your Renoise song). The resulting samples can then be placed into the patterns and will always match your song.
- Record dry (monitor FX): When enabled, the input signals are recorded without the Track FX applied, but will be previewed with them. This way you can hear and record exactly what will be played later when adding the recorded sample to the selected track.
- Create a new instrument on each take: When enabled, each recording is placed into an new instrument slot in the Instrument Selector, so you can simply hit start/stop again and again to create multiple takes without overwriting anything.
- Compensate input and output latencies: When enabled, the latency of your soundcard will automatically be compensated for when creating synced recordings.
- Extra latency (ms): Soundcards or other devices can introduce latencies that Renoise may not be aware of. When your recordings are slightly out of sync on playback, you can manually compensate the latency offset of future recordings here.
- File:Vvoois renoise se recorder start.png Start or stop the recording (changes into "Stop" when recording has started).
- File:Vvoois renoise se recorder done.png Closes the recorder window when no recording is taking place. While recording, this will "Cancel" the current recording.
Recording Without Quantization
Once everything is set up, hit "Start" to begin recording. A red border will appear around the dialog box to indicate that recording is active. To stop recording and load the sample into the instrument slot, simply hit the "Stop" button. Currently active recordings can be discarded by pressing "Cancel".
File:Vvoois renoise se recording.png
Recording With Quantization
When using the quantization (sync start/stop) option, Renoise will make sure that recordings are started or stopped at pattern boundaries only. To use the sync you have to start playing the song first. A progress bar will display playback information.
