Ladder is an analogue-modelled multimode filter. Based on the characteristic ladder filter design used in the iconic Minimoog synthesizer, Ladder brings the smooth, organic sound of the original unit to the Reason Rack. Ladder uses cutting-edge DSP rooted in techniques used in industrial circuit simulators to accurately model its analogue components. Furthermore it extends the original filter with a mixer with simultaneous low-pass, band-pass, and high-pass sources and a unique stereo-spacing effect, resulting in an extremely versatile unit capable of all kinds of effects from gently distortion and deep synth bases to complete analogue mayhem.
FM controls the amount of cutoff modulation from the FM audio input on the back.
Filter cutoff ranging from 20 hz to 20.000 hz
Filter resonance. When emphasis value gets high enough the filter will go into self-oscillation and produce a sine wave.
Here you can mix the output of the different filter modes together.
Controls the level going into the filter. Higher levels results in the filter being saturated.
Controls the output level of the filter. When the AUTO switch is on the level is controlled automatically.
Overload lamp indicates when the filter is saturating the signal.
This adds 20dB of gain to the input for extra saturation.
The output level is controlled automatically.
Spacing shifts the cutoff points of the left and right channel away from each other. The higher the value the further apart the cutoff points we be.

FM input is an audio input used for modulating the cutoff frequency at audio rates. The amount of modulation is controlled by the FM knob on the front panel.
Modulates the cutoff frequency.
Modulates the emphasis amount.
Key Track (keyboard tracking) is used for making the cutoff frequency follow (track) the keys played on your keyboard when a Note CV signal is connected. When the Key. Track amount knob is set to maximum the filter with track the note signal 100%.
Modulates the amount of FM modulation.
Modulates the amount of spacing.
