# Mixer Panel

***

### Overview

Current includes an engine mixer panel. The mixer panel offers a centralized view for adjusting each sound source’s level, with additional options like solo, direct out, and engine output gain.

### Mixer

**1. Solo.** Solo an individual sound source; only one sound source can be soloed at a time. You can also solo a sound source by Command-clicking (macOS) or Ctrl-clicking (Windows) on its icon button in the respective engine tab.

**2. Direct Out.** When active, the sound source will not pass through the filters or effect rack.

**3. Level.** Adjust the gain of each individual sound source. This control functions identically to the Level control found on the individual sound source panels.

**4. Engine Output Gain.** Set the output gain for the polyphonic synth engine before it is sent to the effect rack. This feature is useful for gain staging before reaching the effects rack or for modulating the level of all sound sources simultaneously.
