This is a dual-modulated multi-filter! The cutoff of an LP/BP/HP-filter can be controlled by an LFO and/or a step sequencer. The step sequencer can also control the speed or the modulation amount of the LFO ! Both are synced to host. The LFO can also run at audio rates! (manual or by incoming MIDI notes). And if all this is not enough: both LFO and step sequencer can send their values as MIDI CC messages to control other plugins or synths !
