Logic Pro 7: Avoiding clicks in the audio signal of software synthesizers

Learn how to avoid clicks in the audio signal of ADSR software synthesizers like the ES1, ES2, or Sculpture.

Clicks can appear in some cases when using the ES1, ES2, Sculpture, or other synthesizer while working with an ADSR section.

You can avoid these by paying attention to the following settings:

1. If the "Analog" slider is set to 0% (ES1/ES2), a special feature is invoked, oscillator and filter synchronization. The oscillator and the filter reset at every Note On. This enables the ES1 or ES2 to create synthetic percussion sounds with much attack and best reproducibility. To avoid clicks, set this slider at least to 1%.

   

2. The minimum setting of the attack and release time is 0ms, which means 0ms or 1 sample. So, if you want to avoid clicks from here, allow a little bit of attack. The sliders have a stretched characteristic at the lower end to allow a fine adjustment of the attack and release time.

   

3. If a synth voice is assigned to a new note with a different velocity, and a velocity range is there, you might hear a click, even with slow attack rates, because the ADSR works with the new velocity and immediately changes its output. Assign more voices to the software synthesizer to avoid this.
