Malström Overview Overview (1d) Filter A / Filter B Malström's filters are not all that different from the two filters found on the Subtractor, at first glance. One major difference, however, is in the signal routing: While the Subtractor's filters are hard-wired sequentially, passing the signal from Filter 1 into Filter 2, Malström's filters can be used independent of one another. Each oscillator can be routed to an individual filter, or Filter B can be routed into Filter A in a chain and one or both oscillators can then be routed through the chained filters. Note also that each filter sports a few new modes not found on the Subtractor's main filter. In addition to lowpass (lp12) and bandpass (bp12) modes, the Malström filters also support comb filters, positive and negative polarity (comb+ and comb-) - and an amplitude modulation mode (am). With regard to amplitude mode: you will find that the effect of this filter mode is not audible until you increase the filter's Resonance knob - the greater the value, the more intense the amplitude modulation effect on the signal. There are also buttons for (a) controlling filter frequency with an ADSR-style envelope (env), and (b) making the filter's frequency track the notes of the MIDI keyboard via the kbd button.
