Get A Unique Unit With The Make Noise LxD Dual-Response Low Pass Gate Module

The LxD, Low Strike Duo, is a dual-response, two channel, direct-coupled, Low Pass Gate, which utilizes vactrols in order to provide simultaneous control over the Amplitude and Frequency Spectrum of an INput Signal. It is, in essence, a VCFA (Voltage Controlled Filter Amplifier). Unlike the Optomix, the LxD offers two different filter responses. CH. 1 offers a 12db/Octave response that is mildly-resonant, while CH. 2 offers a 6bd/Octave that is non-resonant. The OUTput of CH. 1 is normalled to the INput of CH. 2. This normalization puts the two channels in series, which is similar to the VCF into VCA arrangement made popular by many monosynths of the 1970s.



  • Classic VCF->VCA arrangement in small 4hp module
  • STRIKE INput allows use of Gate signal to trigger Low Pass Gate circuit, "plucking" or "striking" the vactrol
  • Low noise, low distortion, smooth, natural-sounding circuit
  • Direct coupled, process audio or control signals
  • Utilizes 2 vactrols
  • Pairs well with STO and MATHS


  • Signal Input CH. 1: Direct coupled signal input for the 12db/Octave LPG circuit, capable of accepting audio or control signals. Range of up to 15Vpp.
  • Control Signal Input CH. 1: Direct-coupled, highly sensitive, CV input for the corresponding channel’s vactrol gate. Range 0V-8V.
  • STRIKE Input CH. 1: Gate Input for striking, pinging or plucking the vactrol gate. Expects 8V to 10V Gate or Clock signal.
  • Signal Output CH. 1: Direct-coupled output of the signal applied to the input, as processed by the 12db/Octave low pass gate circuit. 10Vpp (depending upon settings and source material). Normalled to Signal Input CH. 2.
  • Signal Input CH. 2: Direct-coupled signal input for the 6db/Octave LPG circuit, capable of accepting audio or control signals. Range of up to 15Vpp.
  • Control Signal Input CH. 2: Direct-coupled, highly-sensitive, CV input for the corresponding channel’s vactrol gate. Range 0V-8V.
  • STRIKE Input CH. 2: Gate input for striking, pinging or plucking the vactrol gate. Expects 8V to 10V Gate or Clock signal.
  • Signal Output CH. 2: Direct coupled output of the signal applied to the input, as processed by the 6db/Octave Low Pass Gate circuit. 10Vpp (depending upon settings and source material).
