"Sound Pack available here: https://sci-fiaudio.com/product/alter...

A NEW VISION OF FM SYNTHESIS

88 completely new FM patches designed for evolving textures, movement and deep atmospheric sound design.

This collection pushes FM synthesis far beyond classic digital tones, focusing entirely on complex modulation, layered motion and organic transformation. No subtractive-style recreations, no generic presets — every sound in this pack has been built from the ground up to explore the more experimental and expressive side of FM.

Perfect for ambient, IDM, experimental electronica, cinematic sound design and advanced electronic music production."

"Inside the pack:

14 Drones
20 Basses
18 Motion Scenes
16 Hybrid Layers (drones + synths combined in a single patch)
20 Pads

These are not just static presets. Most patches feature continuous movement, evolving modulation and highly textural behaviour. Many sounds include multiple internal layers, with some patches combining up to three or four independent sonic elements inside a single preset.

Expect deep atmospheres, shifting harmonics, unstable textures, evolving tonal motion and rich FM timbres that constantly transform while you play.

The patches include dynamic modulation assignments mapped to the modulation wheel for expressive real-time control. Sounds that benefit from performance dynamics also feature velocity sensitivity for a more responsive and organic playing experience."
