Sample Alchemy Trim mode in MainStage
Trim mode lets you select the exact part of the sample you want to use. You can see the current audio file in the waveform display and directly trim the sample using markers. You can zoom in or out with pinch gestures or scroll using single or two-finger swipes. When you zoom in, the scroll bar indicates the current position within the waveform.
When you click or drag markers and handles in the waveform display, you can trim the waveform more accurately by choosing a Snap value, which allows you to snap the markers to a transient or beat.
Trim mode parameters
Start and end markers: Drag the start and end markers to set the sample start and end points. Playback occurs between these markers.
Snap pop-up menu: Choose a Snap value. In Play mode and Motion mode, this affects the movement of source handles. In Trim mode, the Snap value affects edits to loop start and end markers in the waveform display. The following options are available in the Snap pop-up menu:
Auto: The Snap value is automatically set to the best value based on the selected mode and the sample.
Off: Turn snap off.
Transients: Snap to transients in the sample.
Beat: Snap to beat values in the sample.
Fixed: Set the Snap value to allow source handles to move only on the Y axis (vertically) in play modes and Motion mode.
Zoom in/out: Use the pinch gesture on your Trackpad to zoom in and out of the waveform.
Set trim start and end markers
To set the start and end markers in Trim mode, do any of the following:
Click the Snap menu and choose a Snap value.
Click the start marker then, drag it left or right to set the start position of the sample.
Click the end marker then, drag it left or right to set the end position of the sample.
Note: You can use the pinch gesture on your Trackpad to zoom in and out of the waveform for more precise editing. If you zoom in close to the waveform, swipe to the left or right to see the start or end markers.
