Liść-step is a 16 step sequenced state variable filter.

The cutoff frequency can be controlled in 2 ways, via the 16 step sequencer or low frequency oscillator. Liść-step allows the user to quickly create modulated filter patterns with ease.

State variable filter:

• Low pass, High pass, Band pass, Band reject.
• Frequency cut off.
• Resonance.
• Step sequencer (output to filter frequency).

16 step sequencer:

• Sequencer rate.
• Step amount.
• Sequence direction (forwards, backwards, back and forth 1 and 2).
• Glide amount.
• Amount to cut off.

Low frequency oscillator (ouput to filter frequency):

• 5 waveforms (sine, saw, ramp, triangle, square).
• Square waveform width (pulse).
• LFO rate (free or sync to host).
• Wave position.
• Amount to cut off.
