New Software Synth, Swayed, Recreates Classic Yamaha SY77 Sound

2 Apr, 2026 Software Synthesizers & Samplers

Dutch audio developer Stryde Audio has introduced Swayed, a new software synthesizer that they say is “modeled after a famous 1989 synthesizer that combined FM synthesis with sample based synthesis” (Yamaha SY77).

The combination for FM synthesis and samples expands its synthesis capabilities far beyond what was possible with the better-known DX7, and allows for the creation of a broader range timbres, from realistic to synthetic.

Patch compatibility means you can access the vast library of sounds made for the original hardware, in the form of SysEx files that can be imported. Patches made with Swayed can also be loaded into the original hardware by exporting them as SysEx files.

Features:

FM Synthesis – Advanced FM synthesis module featuring 6 operators, 15 waveforms, up to 3 configurable feedback paths, and 45 algorithms.
PCM Synthesis – Waveform module that can play back multi-samples.
Digital Filter – FM and PCM elements can be shaped using a dual-resonant filter setup: one LPF/HPF and one LPF, both with 12 dB/octave slopes.
Modulation – Individual operator and sample volumes can be automated using envelopes. The same applies to pitch and filter cutoff. Additional modulation is available via 2 LFOs.
Effects – Choose from 44 effect types to give your sounds extra character. Including chorus, flanger, delay, reverb, and distortion. Effects can be routed in 3 different configurations.
Dynamic Pan – Select from 64 panning envelopes to create a rich, evolving stereoscopic sound field.

Swayed is available now for €99 / $99.
