Gem Modula is a comprehensive mixing and mastering plug-in that brings together three legendary modulation effects in a single package. It recreates the distinctive sounds of classic units like the Dimension D, Solina Ensemble, and the SPX90, each known for their unique contributions to music production. Dimension offers a soft, organic modulation ideal for vocals and full mixes, enhancing spatial perception without adding reverb. Ensemble excels with synths and pads, delivering rich stereo depth especially suited for string sounds and soundscapes. Symphonic provides a classic 90s digital chorus effect with a three-voice modulation scheme, favored by renowned guitarists and commonly used on vocals and synths.

Beyond authentic emulations, Gem Modula expands on these vintage effects by integrating modern digital flexibility with the warmth of analog processing. Users can push the input stages into saturation to generate musical harmonics, adding character and richness to the sound. The built-in parametric EQ allows precise tonal shaping of the wet signal without requiring external processing. Stereo width can be adjusted from mono to twice the original breadth, enhancing the spatial experience. A Dual-Mono Mode enables separate processing of left and right channels with independent settings, increasing stereo depth and creative control.

Gem Modula also introduces dynamic and customizable modulation features that respond to the input signal's envelope, making the effect adapt and breathe with the music. This is particularly effective in electronic genres where modulation speed or intensity can shift according to transient peaks or softer passages. The plug-in allows users to modify LFO shapes and filter behavior, enabling experimentation with modulation motion and new textures while preserving the original character. This flexibility makes it possible to transform classic choruses into flangers or other effects, providing a powerful tool for creative sound design.
