MainStage Tutorial: How to assign pitch bend to EXS24 instruments

In this MainStage tutorial, we’ll look at how to assign a pitch bend wheel to EXS24 instruments.

After you’ve set up your controller assignments in your MainStage layout, return to EDIT mode and click on your pitch been wheel icon. It should appear as below with a blue outline.

Select the pitch bend wheel in EDIT MODE

Next, in the screen control inspector select the tab labeled “unmapped”, then select the name of the channel strip you wish to affect. In this case, we’ll be looking to use the pitch bend wheel on the channel strip labeled “Boys Ch”.

In the next column, highlight the line labeled “EXS24 (Sampler)” as this patch is an EXS24 instrument:

Navigate down until you see the folder labeled “Pitch” and highlight that:

In the next column to the right, select “Fine Tune”:

Select “Fine Tune” and adjust the pitch bend range

On the left side of the Screen Control Inspector, you can adjust the range of the pitch bend in the boxes labeled “Range Max” and “Range Min”. I suggest starting with +10 cents and -10 cents respectively, though you can adjust to suit your needs and your taste.

After moving the pitch been wheel while holding a note in the EXS24 instrument to test and verify that it’s working, save the concert.

MainStage Tutorial: How to Edit Tunings of EXS24 Samples in MainStage

I this MainStage tutorial, we’ll look at how to edit pitches in the EXS24 sampler.

It’s not uncommon to discover that one particular sample in an EXS24 instrument is out of tune slightly, particularly if resampled from an external sound library or instrument via Auto Sampler. Or, it may be necessary to adjust the pitch of a sound effect to achieve the desired result. In this post, we’ll explore how to do this.


  1. The first step is to open the EXS24 instrument you’d like to edit by clicking on the plugin within the channel strip in MainStage. This will open a window that looks like Image A below, which is the stock harp patch in MainStage.

  1. Next, click on the edit button just to the right side of the instrument name (immediately above the level fader) to open the edit window.

  1. Now highlight the sample you wish to edit. You can do this by striking the key on your MIDI keyboard that corresponds to the note you need to edit or by simply highlighting it with the computer mouse. In this case, we’ll edit the pitch of note D4. Once you’ve highlighted D4, you’ll see something that looks like Image C.

  1. Since in this case, we’ll be editing the fine tuning of the pitch, we’ll double click the number in the column corresponding to the fine tuning of the highlighted sample. However, you could highlight any of the elements you wish to edit.

  1. Now simple type the number that corresponds to the degree to which you need to adjust the tuning. In this case, I’ve already checked the pitch against the built in tuning from MainStage, so I know that the pitch needs to be adjusted up by 10 cents. Therefore, I’ll type the number 10 into the highlighted area. If we needed to adjust the note down by 10 cents, we’d simply type “-10” instead of “10”. In the upper left corner of the edit screen, you’ll see a red dot. Click on this red dot to open the prompt to save.
  1. When prompted as to whether you’d like to save your changes, select save.

  1. Close the instrument by clicking on the grey dot in the upper left hand corner of the EXS24 instrument.

  1. Save the concert and reopen it. Your changes should now take effect for any instances of the edited instrument.

You could use this process to edit any of the parameters in the EXS24 instrument. This is particularly helpful if you’re unsatisfied with the tuning of a particular note, need to edit the range of a note, or if you need to adjust the volume of specific samples.
