Description

The VCA Matrix from 4ms is a playable 4×4 matrix of 16 VCAs. The four audio/CV inputs can be routed and mixed in any combination to the four outputs, with independent CV control of each VCA. It is also a fully voltage-controlled Matrix Mixer.

In basic terms, you could think of it as a 4 channel mixer, with 4 AUX / FX sends per channel. These are all able to be muted at the touch of a button, and have full independent voltage control via the 16 available VCAs and their corresponding CV inputs.

Features:

  • 4 CV/audio inputs and 4 outputs (buffered and dc-coupled)
  • Full range (0Hz – 20kHz) for both Control and Signal inputs, allows for AM effects, etc.
  • 16 VCA’s using high quality SSM chips
  • Attenuation/gain range from -100dB (mute) to 0dB (unity). Up to +20dB boost with trimpot adjustment.
  • Playable surface with 16 latching Mute LED buttons, used to mute each VCA individually (Mute button disconnects Control jack and Level knob, and fully attenuates the VCA)
  • LED button brightness indicates amount of attenuation and Control CV signal
  • 16 Control jacks for VCA level control
  • 16 Level knobs attenuate the incoming Control signals. The Level knobs act as manual level controls when nothing is plugged into the Control jack
  • Exponential VCA response in low control voltage range, pseudo-log response in higher voltage range.
  • “Soft Limit” effect limits gain to prevent clipping, while still responding to higher Control voltages with more “punch” and wider pulses
  • Matrix Expandability: VCA Matrices can be connected to form a larger matrix using headers on the back (4×8, 8×8, 12×4, etc)
  • Control Expandability: 16-pin header on back side of PCB allows an external device to control all VCAs: e.g. patch recall, patch sequencing, preset patterns such as quadrature panning, etc.
  • Suitable as a 4×4 mixer, splitter, dynamic signal router, limited waveshaper, etc.
