Groove Synthesis 3rd Wave 8M 8-Voice Desktop Synthesizer

The Groove Synthesis 3rd Wave 8M is a streamlined desktop synthesizer that delivers the same powerful sound engine and premium build quality as the flagship 24-voice 3rd Wave models, but in a compact, 8-voice format. Designed for producers, composers, and performers who want maximum sonic versatility without sacrificing space, the 8M offers bi-timbral operation, a larger display for deep sound design, and a performance-oriented control set.

Fully patch-compatible with the 24K and 24M models, the 3rd Wave 8M integrates seamlessly into any studio or live setup and provides a cost-effective entry point into the 3rd Wave ecosystem. With advanced wavetable synthesis, lush analog filters, and flexible sequencing options, the 8M combines classic digital heritage with modern sound-shaping power.

Classic Legacy, Modern Sound
Inspired by iconic digital wavetable synthesizers of the past, the 3rd Wave 8M pushes the concept into the modern era. Its three high-resolution oscillators per voice deliver rich wavetables, analog-style synthesis, FM, and sampling capabilities. The instrument features a punchy Dave Rossum–designed 2140 analog low-pass filter with variable saturation, plus a versatile SEM-style state-variable filter (low-pass, high-pass, notch, and band-pass). Both filters can be run in series for harmonically complex and evolving textures.
