Groove Synthesis 3rd Wave 24 Voice Module - 24M

24-Voice Wavetable Desktop Synthesizer

• 24-voice polyphony and 4-part multitimbral operation
• 3 digital oscillators per voice: classic PPG wavetables, modern high-resolution wavetables, and analog-modeled waveforms
• Dual filters: Dave Rossum 2140 analog filter and SEM-style state-variable filter
• Built-in Wavemaker™ for creating custom wavetables from samples
• Pattern-based sequencer for notes, songs, and parameters, with a dedicated arpeggiator
• Modulation matrix with 16 assignable slots, 27 sources, and 114 destinations
• 2 digital effects for multi-part sounds and 4 LFOs for additional modulation

The Groove Synthesis 3rd Wave 24M is a desktop wavetable synthesizer with an epic, modern sound, capable of delivering up to 24-voice polyphony and 4-part multitimbral operation—like having four independent synthesizers at your fingertips. Each voice features 3 configurable oscillators—ranging from PPG-era wavetables to modern high-resolution wavetables and analog-modeled waveforms—offering an extremely wide sonic palette.

With the Wavemaker™ tool, you can create up to 64 custom wavetables by sampling any audio source directly from the dedicated input: simply connect the source and press a button to generate a new wavetable, making wavetable synthesis more accessible and experimental than ever.

Dual Analog Filters for Complex Sound Textures

The 3rd Wave 24M’s sound engine builds on the concept of classic digital wavetable synths, bringing it into the present with a rich, organic sound. The 2140 analog low-pass filter, designed by Dave Rossum, offers a 24dB per octave slope with variable saturation, while the second SEM-style state-variable filter adds low-pass, high-pass, notch, and band-pass modes. The two filters can be routed in series for even more complex harmonic textures.

4-Part Multitimbrality for Complex Performances

The 24-voice polyphony really comes into its own in multitimbral mode: up to 4 independent parts, each with dedicated sound, sequence, and effects, or 4 separate split zones. Each stereo part features panning, volume, and a dedicated physical stereo output, while the 3 wavetable oscillators per voice/part each have their own loopable 6-stage wave envelope, for an ever-evolving soundscape.

Sequencer and Modulation Matrix for Sound Design

The 3rd Wave 24M’s pattern-based sequencer handles both notes and parameters, with real-time recording achieved simply by holding down Record and turning a knob. Each multitimbral part has its own sequencer track, while the modulation matrix—with 16 free slots, 12 fixed routes, 27 sources, and 114 destinations—offers flexibility comparable to a modular system.
