There’s a right way to acidize, and a wrong way — this is definitely the wrong way

Objective: Use the Loop Construction window not so much to acidize, but as a “step sequencer” to add synchronized level-altering effects.Background: Sonar can time-stretch files by adding markers at transients, then using DSP to extend or shorten the duration of each slice delineated by these markers. But it’s also possible to add markers at arbitrary rhythmic points, and use gain envelopes to vary each slice’s level.

1. Drag a file, such as a sustained guitar power chord or pad, into an audio track.

2. Trim the clip length to a measure boundary by slip-editing the left edge, then click on the clip and go Edit > Bounce to Clip(s). This “fixes” the clip length at the measure boundary.

3. Double-click on the clip to open up the Loop Construction window.

4. Enter the clip’s duration in beats in the “Beats in Clip” field. Under “Slices,” select Eighth Notes (for an eighth-note rhythm) from the drop-down menu, and set “Trans Detect” to 0.

5. Click on the Gain Envelope icon.

6. Drag the gain envelope as desired for each slice to create a “level step sequence.”
