More Creative Potential Than Your Typical VCA Module

Get to know them!

The 4ms VCA Matrix Eurorack module is a versatile VCA module that encourages hands-on creativity. Each of its four CV/audio inputs can be routed to their four corresponding outputs in any amount and in any combination. This is accomplished via the individual trimpots for each of the 16 VCAs, allowing you to mix signals in real time. A bank of 16 mute buttons further rewards hands-on spontaneity. For optimal sonic performance, the VCA Matrix module's VCAs feature exponential response at low voltage levels and pseudo-log response at higher voltage levels. And synthesists at Sweetwater dig the expandable nature of the 4ms VCA Matrix — multiple matrix modules can be connected to form larger matrices.

4ms VCA Matrix Eurorack Module Features:

  • Multi-VCA module for Eurorack modular synthesizers
  • 4 CV/audio inputs can be routed to a set of 4 outputs in any amount/combination
  • 16 VCAs, each with trimpot (-100dB to 0dB, or +20dB with trimpot adjustment)
  • 16 mute buttons encourage real-time interaction
  • Soft Limit circuitry to prevent clipping
  • Multiple modules can be connected to create larger matrices
  • Exponential VCA response in low control voltage range, pseudo-log response in higher voltage range

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
