Groove Synthesis - 3rd Wave 8M
THE MOST ACCESSIBLE WAY TO THE 3RD WAVE SOUNDThe 3rd Wave 8M puts professional-grade synthesis within reach. This isn’t a watered-down version. This is 8 voices and 2 parts of pure, uncompromised 3rd Wave in a more accessible, compact package. Same premium sound engine, analogue filters, and build quality found in our flagship instruments, now in a compact desktop format that fits more budgets and more spaces.
Every voice runs through a Dave Rossum-designed 2140 analogue lowpass filter with variable saturation, paired with a SEM-style state-variable filter offering lowpass, highpass, notch, and bandpass modes. This is the same signal path that is in our flagship 24-voice instruments. The DC-coupled output stages deliver low-end power you don’t just hear but feel. Eight voices through this signal path will fill a room.
The 8M’s interface focuses on what matters most during performance and sound design. The streamlined front panel puts essential controls under your hands: oscillator selection, filter cutoff and resonance, envelope controls, effects. Everything you need to shape sound in the moment. The 7-inch display with six context-sensitive encoders provides more screen space and more simultaneous control than even our flagship models. Navigation is immediate. Deep parameters are accessible without menu-diving.
Amazing Features
• Classic PPG-era wavetables with the authentic processing chain and imaging character that defined ’80s electronic music
• Modern high-resolution wavetables with Serum wavetable import capability for contemporary sound design
• Analogue-modeled waveforms for classic subtractive synthesis tones
• Three operator linear FM per part for metallic, bell-like, and complex harmonic textures
• Multi-sampling of up to 8 samples across the keyboard
Patch Compatibility
more potentialEvery patch created on the 8M loads directly on the 24M and 24K. Start a sound on the road, finish it in the studio. Collaborate with other 3rd Wave owners regardless of which model they have.
Patches from the larger models load on the 8M as well, as long as they only use two parts.
Built for Modern Workflows
versatile controlFour balanced outputs handle stereo operation or discrete part routing. Full MIDI I/O via DIN and USB integrates with any setup. MPE and polyphonic aftertouch support capture every nuance from expressive controllers like the Roli Seaboard or the Expressive E Osmose.
The compact desktop format fits where larger synths can’t. On a crowded desk, in a travel bag, or mounted in a rack with the included 19″ ears.
