Sampler Keyzones

Keyzones

For each sample in an instrument the Keyzones editor can create a zone that stretches across a range of key and velocity values. When a note is played, any sample whose Keyzone contains that note's key/velocity co-ordinate will be triggered. This can be done for both Note-On (key press) and Note-Off (key release) inputs, via separate layers.

The Interface

The Keyzones interface consists of a large central section that displays the zones, with various options above and below. The note range that can be played within Renoise (C-0 - B-9) is represented horizontally, while the velocity range of 00-80 is shown vertically. This grid is used to create a Keyzone's range for a sample. Playing notes will display their coordinates on the grid.

Placing the mouse pointer over the grid and scrolling the mouse wheel will zoom in/out, giving you access to more/less detail horizontally and the scrollbar underneath can be used to move around.

Creating Keyzones

Selecting & Adjusting the Zones

A zone can be selected by left-clicking on it or by selecting a sample from the Sample List. This becomes the active zone with a highlighted colour and small squares on of each of its four sides. The size and position of a zone is displayed in the Note Range and Vel. Range value boxes at the bottom left of the interface, which can be used to make changes. If you left-click and drag the active zone's edge you can resize it, while doing this inside the zone will move it around.

If you hold down the left "Shift" key and left-click on another zone, both this and the active zone are selected, along with any zones between them on the grid. You can also left-click (anywhere other than the active zone) and drag to select a range of zones. Holding the left "Ctrl" key ("Command" on Mac) and left-clicking on zones will select/deselect them, allowing you to pick any combination from the grid. When multiple zones are selected, any changes made to the active zone will also affect the others.

• Double clicking a zone will open the sample in the Waveform editor.
• It is possible to have overlapping zones, so that multiple samples can be triggered at once with a single note.
• If the Auto-select option in the Sample List is enabled, zones will be automatically activated by notes that are played within their range.

Inserting & Deleting Zones

To create a new Keyzone you can either insert a new sample via the Sample List or right-click on the grid to open the context menu and choose "Insert New -> Load Sample(s)". Alternatively, select one or more samples from the Disk Browser, drag them onto the Keyzone grid and place them where you want (the horizontal size can be adjusted by moving the mouse pointer up and down before letting go of the mouse button).

A zone can be deleted by selecting it and pressing "Delete" or using the right-click menu and selecting "Remove".

Note On/Off Layers

At the top left of the interface are two buttons that switch the grid focus between creating Keyzones for "Note-On" and "Note-Off" inputs, allowing for the triggering of samples for both the pressing and releasing of a note. It is possible to have a sound only play when a note is released by making its grid co-ordinate have a zone in the "Note-Off" layer but not in "Note-On".

Automatically Distributing Zones

You will find the options for this in the top right corner of the Keyzones interface.

• Drumkit: This will assign each zone to a single key, starting from the note selected in the value box. Opening the drop down menu will reveal two additional options. "Use White Keys Only" will only assign zones to the white keys, while "First Octave for Transposing" will assign an entire octave to the first sample of the instrument.
• Distribute: This evenly distributes all zones across the entire key range.
• Layer: Every zone will span the full key and velocity range. This causes all of an instrument's samples to be activated simultaneously by any note.

Keyzone Options

• Basenote: First, select the Keyzone(s) then right-click on the desired Basenote from the key range along the top/bottom axis of the grid (this can also be changed using the Basenote option at the bottom left). A coloured block on both axes shows the current location of the Basenote. When new Keyzones are created the Basenote will be automatically assigned. When moving a Keyzone around the grid, its Basenote will remain the same.

Using Instrument Envelopes

Using Keyzones with a Sliced Sample

With a sliced sample your options are far more limited. Zones cannot be adjusted by velocity and (aside from the initial sample) can only be a single key in width. Additionally, zones cannot be inserted into the Note-Off layer and you have no control over the use of Instrument Envelopes. However, the Drumkit button and its options are still available.
