u-he Melt

A variable-character analogue filter, from soft to wild.

14 HP Eurorack module

Melt is a four-pole analogue low-pass filter for Eurorack with a variable character, three main audio inputs, an auxiliary bypass path, cutoff FM, resonance control, and VCA-controlled low-pass and band-pass outputs.

Features

  • Four-pole analogue low-pass filter with variable character.
  • Two cutoff-FM paths; FM1 adds polarity inversion and CV-controlled depth.
  • Auxiliary input bypasses the filter and feeds both outputs.
  • Independent CV-controlled VCAs on the low-pass and band-pass outputs.

Controls & Jacks (26)

  • Low-pass Output— Voltage-controlled low-pass audio output; its VCA is controlled by the Low-pass VCA CV input.
  • Core Temperature— Drives asymmetric soft clipping in the filter core, from relatively clean to heavily saturated character while compensating output level.
  • Input 3 Level— Sets the attenuated level of Input 3 in the filter mixer.
  • Band-pass Output— Voltage-controlled band-pass audio output; its VCA is controlled by the Band-pass VCA CV input.
  • Low-pass VCA CV— CV input controlling the low-pass output VCA; normalled to 7.5 V when unpatched.
  • Resonance CV— CV input for resonance amount.
  • FM1 Depth— Sets FM1 cutoff-modulation depth, with its polarity and depth also affected by the associated switch and amount CV input.
  • Input 1 Level— Sets Input 1 level and attenuates its voltage-controlled VCA level.
  • Cutoff Frequency— Sets the filter cutoff frequency.
  • FM1 Amount CV— CV input that adds to or reduces FM1 modulation depth.
  • FM2 Cutoff CV— Cutoff-frequency modulation input for FM2.
  • Aux Input— Auxiliary audio input that bypasses the filter and is routed to both output VCAs.
  • Band-pass VCA CV— CV input controlling the band-pass output VCA; normalled to 7.5 V when unpatched.
  • Aux Level— Sets the level of the auxiliary signal through its dedicated VCA; the auxiliary signal bypasses the filter.
  • Input 1 Level CV— CV input controlling the VCA for Input 1's level; normalled to 7.5 V when unpatched.
  • Aux VCA CV— CV input controlling the auxiliary-input VCA; normalled to 7.5 V when unpatched.
  • Resonance— Sets internal filter feedback; the filter can self-oscillate.
  • Low-pass Slope— Selects the low-pass filter slope: 12, 18, or 24 dB per octave; the 18 dB output is phase-inverted.
  • FM1 Cutoff CV— Cutoff-frequency modulation input for FM1, processed by the FM1 depth, polarity, and amount-CV controls.
  • Input 2 Level— Sets the attenuated level of Input 2 in the filter mixer.
  • Input 3— Audio input 3 to the filter mixer.
  • Input 1— Audio input 1 to the filter mixer; its level is voltage-controlled by the Input 1 Level CV input.
  • Input 2— Audio input 2 to the filter mixer.
  • FM2 Depth— Sets FM2 cutoff-modulation depth.
  • FM1 Polarity— Inverts the phase (polarity) of the FM1 cutoff-modulation signal.
  • Resonance Compensation— Enables resonance compensation to counter the bass and level loss associated with high resonance.
