Groove Synthesis 3rd Wave 8M – Premium 8-Voice Wavetable Synth Module
The 3rd Wave 8M by Groove Synthesis brings the iconic 3rd Wave engine into a compact desktop format — offering the same high-end sound architecture used in the larger 24-voice versions, now with 8-voice polyphony and 2-part multitimbrality for a more accessible price point. [oai_citation:0‡Groove Synthesis](https://groovesynthesis.com/8m/?utm_source=chatgpt.com)
With three oscillators per voice, multiple synthesis types (wavetable, virtual-analog, sampling, FM), analog-style filters, a deep modulation matrix and comprehensive I/O, the 8M is built for both studio and stage use.
Key Features & Highlights
- 8-voice full 3rd Wave sound engine with three oscillators per voice. [oai_citation:1‡Sweetwater](https://www.sweetwater.com/store/detail/3rdWave8M–groove-synthesis-3rd-wave-8m-8-voice-desktop-synthesizer-module?utm_source=chatgpt.com)
- 2-part multitimbral operation — two independent layers each with their own effects, sequencer/arpeggiator and stereo output. [oai_citation:2‡soundonsound.com](https://www.soundonsound.com/reviews/groove-synthesis-3rd-wave-8m?utm_source=chatgpt.com)
