Frequently Asked Questions
The SF1’s stereo link is clean and phase-coherent, offering a wide stereo image without the muddying that can plague some cheaper designs. The panorama control allows for precise stereo width adjustment.
The overdrive is more of a gritty enhancement than full-blown distortion; it adds harmonic richness and a bit of edge, but can quickly become aggressive if pushed too far.
The 1V/oct input allows for tracking the pitch of an oscillator, creating a dynamic filter sweep that follows melodic changes; it's a great tool for creating evolving textures and rhythmic patterns.
