Additionally, it includes two unique 8-step Flow LFOs, enabling users to select and modulate waveforms dynamically, with the option to draw custom wave shapes for truly personalized modulation sources.

F.'em is built for both sound designers and performers, offering an extensive modulation matrix with hundreds of entries, plus a modifier matrix to further shape sounds. Its user-friendly interface features macros for quick adjustments, layered architecture with multiple effect slots, and a versatile arpeggiator that adds creative rhythmic possibilities. Whether diving deep into synthesis or seeking immediate inspiration, this synth delivers rich textures and powerful sound design tools.
