BLEASS Omega Synth: User-Friendly FM Synthesizer Free Download

Omega uses four FM operators, each generating a sine wave shaped by its own ADSR envelope and volume control. Eleven algorithms route the operators in different ways, and colour-coded diagrams show how each one is connected. In every algorithm, the fourth operator includes a feedback loop that modulates its own frequency, controlled by a Feedback setting.

Operators can follow the keyboard or hold a fixed frequency, with Coarse, Fine, Frequency and Multiplier controls for tuning. A global Time control scales the envelopes of all four operators at once, which is useful when shaping attack and decay across a patch.

The Waveshaper offers nine shaping algorithms for warmth and overdrive, and the multi-mode filter provides low-pass, high-pass, band-pass and notch responses. Cutoff and resonance can be set by dragging inside the filter display, and keyboard tracking and envelope amounts control how the filter responds to pitch and playing.

Two LFOs and a third ADSR envelope can each be assigned to up to two destinations. The LFOs offer sine, triangle, saw up, saw down, square and sample-and-hold waveforms. A Motion Sequencer adds repeating modulation patterns that can sync to the DAW or restart on each note.
