Designed specifically for the SE-02, the EXT Box is a multi-function external controller, offering high CV resolution filter frequency control with a full-sized knob. It also features an 1/8" to 1/4" connection converter for External Input and Audio Out. A drive-adjustable hi-pass filter with attenuation, rich overdrive and extremely potent boost, add rich character and depth, while expanded external input control, expressive gate triggering for external signal/sample manipulation, expand and inspire; let it breathe new life and fire into your beloved (and usefully compact) SE-02.
And what the Ext Box does for the SE-02, it can for many desktop synths and modules which offer some combination of External Input control, CV, Gate, and VCF CV connections; we recommend our Boomstar and Boomstar Modular Eurorack modules—especially the Tonestar.
