Groove Synthesis - 3rd Wave 24M
FLAGSHIP POWER. DESKTOP FORMAT.You already have a controller you love. Maybe it’s an 88-key weighted board. Maybe it’s an Osmose or Seaboard. Maybe you’re sequencing everything from your DAW. The 3rd Wave 24M gives you the complete flagship experience without a keyboard that you won’t use. Same 24 voices. Same four independent parts. Same analog filters and output stages. Just a smaller footprint and a friendlier price.
This isn’t a stripped-down version. The 24M runs the identical sound engine as the 24K keyboard, down to the component level: the Dave Rossum-designed 2140 analog filters, the SEM-style state-variable filters, the DC-coupled output stages, and the eight separate outputs for maximum routing flexibility. Every patch you create on the 24M loads directly on the 24K, and vice versa. Your sounds travel with you.
With four independent parts, each with its own sound, sequence, effects routing, and dedicated stereo output, the 24M handles complete arrangements internally. Layer massive pad stacks. Run four sequences simultaneously. Build entire tracks within a single preset. When you need to bounce stems, each part has its own output pair for clean separation.
Amazing Features
• Classic PPG-era wavetables with the authentic imaging character and processing chain
• Modern high-resolution wavetables with Serum import
• Analogue-modeled waveforms for subtractive synthesis
• Linear FM for complex harmonic textures
• Sampling that allows up to 8 audio samples across the keyboard
Built for Your Workflow
FIVE SYNTHESIS METHODS. EVERY SOUND.The 24M integrates seamlessly with modern production setups. Full MIDI I/O via DIN and USB. MPE and polyphonic aftertouch support for expressive controllers. Eight outputs for multitrack routing or live sound. Clock sync for hardware sequencers.
The knob-per-function panel means you can program sounds without touching a mouse. When you need to go deeper, the 5-inch display and four encoders provide fast access to every parameter.
