The Sanford Super Filter features two multimode filters that can be routed in serial or parallel modes. It had two independent LFOs and an envelope follower that can be used as modulation sources. Each filter lets you modulate its cutoff frequency with two modulation. sources. In addition, you can modulate the resonance as well. The versatility of the LFOs and the envelope follower give you plenty of modulation possibilities.
* Two independent filters, each with LP, HP, and BP modes
* Each filter can take up to three modulation sources
