Topaz E.P.1 offers an authentic Fender Rhodes 73 experience through meticulously sampled sounds. It focuses on delivering rich, expressive electric piano tones by combining three distinct layers—soft, mid, and high—that capture the instrument's dynamic range and character.

Users can customize the sound further with individual volume controls for each layer, allowing precise blending to suit different musical contexts. The built-in host-synced tremolo adds rhythmic movement, enhancing the instrument’s classic vibe.

Additional sound shaping options include a six-stage stereo phaser and a Moog-style low-pass filter, enabling lush modulation and tonal warmth. These features provide a broad palette for shaping vintage electric piano sounds with depth and dimension.
