Rave Generation Trigger Rhythm

SY-1K Trigger Rhythm is a modern recreation of a distinctive 1980s analog drum synthesizer, known for producing some of the most recognizable electronic percussion of the decade.

From the deep toms in Phil Collins' "In the Air Tonight" to the sharp snares that defined pop and rock during that era, its unique character left a lasting mark on countless recordings.

The plugin features original components such as dual CMOS 4069 triangle wave oscillators, asymmetric filter pole spreading, pitch sweeps driven by envelopes, and the characteristic non-linearities of CMOS circuits.

On top of the vintage design, it includes five additional waveforms, tempo-synced LFOs, MIDI key tracking, and a modern drive circuit for added saturation.

SY-1K Trigger Rhythm balances classic analog tone with expanded control and flexibility.

It covers a wide range of styles, from authentic gated reverb sounds to detailed EDM percussion, offering both the character of vintage hardware and the workflow of a modern plugin.
