Using Groups

In the EXS24 Instrument Editor, you can organize zones into groups to apply common parameters to multiple zones simultaneously. Groups contain many of the same parameters you use in zones, but they also offer some unique parameters. For example, you can offset both the filter settings and the envelopes, which allows you to create different cutoff and resonance values for different zones.

In the sampler instrument you created, the low-pass filter cut out the high frequencies of all samples. By using groups, you can, in effect, apply a different cutoff frequency for just the snare hits.

  1. In the EXS24 interface, click the Edit button to open the EXS24 Instrument Editor.
  2. From the local menu, choose Group > New Group.

    A new group, named Group #3, appears in the Zones column.

  3. In the Zones column, double-click the new group name (Group #3), and enter Filter. Press Return.

    To display the newly created group’s parameters, you need to switch to Groups view.

  4. Click the Groups view button.

    The group parameters appear.

  5. In the Filter Offsets parameters, double-click the Cutoff field and enter –5 to lower the filter cutoff frequency for any zone assigned to this group. Press Return.

    Now that you created and modified the group, you’ll assign the zones to it using the Zones view.

  6. Click the Zones view button.

    You might be asking yourself, “Where did the zones go?” Not to worry; you are currently viewing the Filter group, which does not yet have any zones assigned to it.

  7. Click the All Zones group to display all zones.

    You can easily assign zones to groups by dragging them onto the groups in the Zones column.

  8. Command-click the zones mapped to D3 and F#3 to select them.
  9. Drag the selected zones to the Filter group.

  10. In the Zones column, select the Filter Group.

    The two zones you added appear.

  11. Play the project, listening to the result.

    The snare samples mapped to D3 and F#3 have a slightly different filter cutoff frequency, thereby changing their sounds.
