Mutable Instruments Blades
Dual morphing filters with drive and wavefolder
18 HP Eurorack module
Blades is a dual multimode filter with built-in drive/wavefolder circuits. Each filter can morph continuously between low-pass, band-pass, and high-pass responses, while the drive section provides everything from clean gain to aggressive wavefolding distortion.
