Spectral Sampling™ Engine A completely brand-new algorithm that doesn't just hold notes, it analyzes notes at the spectral level and captures the true timbre, dynamics, harmonics, and character of any input with stunning realism, preserving the expressive nuances of any instrument you play and extending them into evolving sonic textures. Auto Layer Catch The PLUS Pedal II detects new note events, filters out noise, handles transitions, and stacks sounds with remarkable musical accuracy. The result feels natural, almost like playing a piano with a sustain pedal without any thought or technique. Gradual Optical control A new optical sensing system reads the brass pedal's position across the whole movement range, allowing you to use your foot to control the volume and release curves of all sustain layers! Layer control Lets you choose how many active layers the pedal maintains: • 1 layer: Maximum clarity, clean sustain under a single note or chord. • 2-10 layers: Building rich harmonic structures, chord beds, and complex textures. • Infinite: Combines older layers for endless evolving soundscapes. Each active layer is represented on the circular LED halo display for real-time visual feedback. Combo XLR/TS Input + Built-in Mic Preamp Use the XLR input to connect microphones directly then adjust the gain control. Using the jack input to connect guitars, vocals, microphones, and acoustic instruments bypasses the preamp completely and behaves like a traditional instrument input. A Kill Dry switch lets you use PLUS Pedal II for sustain layering only, while your instrument sounds naturally in the room. Dual Resonator + Dynamic Tone The built-in dual resonator engines continuously responds to the spectral content of each active layer, generating ever-shifting upper and lower resonances. Every new note changes the harmonic ecosystem, creating movement and organic complexity that feels alive, unlike a static effect.
