Stylophone DF-8 Compact Portable Modular Filter Box

This cutting-edge filter unit combines the precision of a smooth analog recreation of the classic 2045 Lowpass filter with the bold, dynamic character of Stylophone's proprietary GEN R-8 filter. Dubbed "Beauty and the Beast," the DF-8 offers unparalleled flexibility. The 2045 filter delivers a silky 24 dB/octave Lowpass mode, while the GEN R-8 snarls and howls in all four modesLowpass, Bandpass, Highpass and Notch. Together, these filters unlock three additional combination types: Bandpass+, Band Reject+, and a wide Notch+ mode, providing an expansive palette of unique filter sounds.

Both filter channels have all eight filter types and are controlled by two full ADSR envelopes with multiple trigger modes to cater for every need. They can be triggered by a gate signal, by an audio signal threshold, by a manual trigger button and they can even autorepeat in a loop mode acting as LFOs.

The DF-8 is so much more than a dual filter box - it's a complete sound design tool. Equipped with two white noise sources, a sample-and-hold modulation source with adjustable slew, and a crunchy PT2399 delay with modulation, it serves as a sound source capable of everything from subtle atmospheres to all-out sonic chaos. Like all CPM units, the DF-8 is designed for portability and flexibility.
