Web Harmonium Simulator Parameters

Master these controls to customize your Web Harmonium experience.

Volume

Adjust the overall loudness of your Web Harmonium. Set it higher for performance or lower for quiet practice sessions with headphones.

Reverb (Convolution)

Add spatial depth and ambience to simulate different room acoustics. Higher reverb creates a concert hall feel in your Web Harmonium.

Transpose

Shift all notes up or down by semitones. Perfect for accompanying vocalists in different keys without changing your finger positions on the Web Harmonium.

Octave

Reeds

Release

Control how quickly notes fade after releasing the key. Longer release times create smoother, more sustained tones on the Web Harmonium.
