The Oscillator Mixer section combines both oscillator signals prior to the filter.

Controls

Level- Sets the amplitude of each oscillator.

Pan- Sets the panning of each oscillator - remember that following the mixer, Harmonia's entire signal "under the hood" is stereo, so pan settings are retained.

Mute (M)- Allows muting of either oscillator. The button will glow red when the oscillator is muted. This is generally used for temporarily disabling an oscillator when programming sounds, but Mute button status is saved with patches.
