Check out the new Dwarfcraft ARF (Attack Release Filter). It’s everything you ever wanted in a filter, complete with a picture of a sexy lady with a dog’s head. Naturally. The Attack/Release envelope has a huge range and the activation of the envelop and the duration of the sustained peak are controlled by a foot switch or CV gate signal. The envelope is then routed to an aggressive low pass filter with enough “extra” on the resonance to get some self oscillation. The filter cutoff can also be controlled via CV input. There are also CV outs for integration with your synth or Eurorack set ups.
