What V.A.S.T. Means in Practice
- Variable Architecture: You can build complex sounds by routing and combining different processing blocks—oscillators, filters, EQs, envelopes, LFOs, etc.—in almost any order you choose.
- Layered Sound Design: Each "Program" in V.A.S.T. can contain up to 32 layers, each with its own synthesis path, modulation, and key/velocity mapping. This allows for deeply detailed and expressive patches.
- Extensive Modulation: Nearly every parameter can be modulated using velocity, aftertouch, envelopes, LFOs, external controllers, and more—ideal for advanced sound design.
- DSP Power: V.A.S.T. runs on powerful internal DSP chips, offering near-instant processing and the ability to create both synthetic and highly realistic acoustic sounds.
Why Choose the K2061?
The K2061 provides a synthesis playground matched with real-time performance power. Its expressive keyboard, instantaneous sound access via FlashPlay, deep layering through V.A.S.T., hands-on controls, and a full sequencer make it ideal for composers, live performers, and sound designers seeking both creative depth and reliability.
