The SY-1000 represents a quantum leap in guitar synthesis technology, combining decades of BOSS innovation with cutting-edge DSP processing and evolved GK technology. This revolutionary creation machine opens up limitless sound design possibilities for guitarists and bassists, featuring three simultaneous instruments with premium processing power. The result is the most organic playing experience and finest performance quality BOSS has achieved in their guitar synth legacy.
At the heart of this powerhouse lies the groundbreaking Dynamic Synth engine, which pushes guitar synthesis into uncharted territory. Ten oscillator waveforms including sine, triangle, PWM, and Roland’s famous supersaw provide the foundation, while six different filters, amplifier control, dual LFOs, and two step sequencers shape your sound with precision. The GK processing tracks your instrument’s characteristics in stunning detail, enabling sounds previously impossible to achieve.
Two 16-step sequencers add movement and complexity to your creations, with independent control over pitch, filter, and amplitude. Each step features 13 different envelope curves for unprecedented sonic control, allowing you to craft textures that pulse, breathe, and groove with your playing. Beyond the Dynamic Synth, you’ll find the analog-style OSC Synth with comprehensive ADSR control, plus a faithful recreation of the legendary Roland GR-300 from the 1980s.
With freely configurable footswitches, outputs, and external controls, the SY-1000 adapts to any workflow while providing refreshed instrument modelling derived from historic BOSS and Roland GK gear. From intense analog-style leads and warm pads to modelled electric and acoustic tones, this sonically vast instrument serves as an infinite well of inspiration for your musical vision.
