Flexible Envelopes for Extreme Sound-shaping Fun

Get to know them!

While there are many wonderful envelope generators available for Eurorack rigs, the 4ms Pingable Envelope Generator offers a unique set of functions and features that are sure to please any creative synthesist. This module provides you with two envelope generators that sync to either a tap tempo control or incoming pulse clock. Both generators include a time divider/multiplier, which lets you offset them from the main clock by 1/8 to 8 x the clock time, allowing you to set up complex modulation schemes. The Pingable Envelope Generator also provides you with extensive waveshaping controls, allowing you to fully adjust their contours and behavior.

Shift and scale your envelopes

One thing that makes the Pingable Envelope Generator so flexible is the way it lets you adjust the scaling for either envelope independently. The Scale knob itself lets you set the maximum output to up to +10V or to invert the signal and set it down to a maximum of -10V. Hit the Bi-polar switch, and the entire generator will center around 0V with an output range of +/-5V. At the same time, you can bypass the Scale or Bi-polar settings via the +5 Env output, which always produces output ranging from 0 to +5V. Finally, there's the OR jack, which outputs whichever envelope is the hottest, accounting for both Scale and Bi-polar settings.

Fire off gates in a variety of ways

One of the things the synth geeks here at Sweetwater noticed right away about the Pingable Envelope Generator is the variety of gate outputs 4ms gave it. There are two main available gate conditions: End-of-Rise, which goes high when at the tail end of the envelope's rise portion and goes low when it begins its next rise, and End-of-Fall, which is the inverse of End-of-Rise. You can turn either of the End-of-Rise outputs into a Half-Rise envelope (which goes high after 50% of the rise time elapses and goes low 50% of the way through the fall time) via a jumper. What's more, the Skew parameter jack acts as a variable phase gate output, which lets you lock into the timing and triggering of other effects modules.

Cool triggering/cycling options

Dedicated trigger inputs let you set off your envelopes in a few different ways. You can simply hit the cycle button for either channel to self-cycle its envelope to the ping clock. If you pulse the T jack, that will toggle the state of both channels together. Each channel has a QNT jack for manually triggering its envelope start at the next quantized beat as defined by the Ping Div/Mult control, which is perfect for setting up synchronized patterns. Conversely, the Async jack lets you fire off envelopes immediately. A quick pulse will trigger the envelope once, but you can cycle the envelope repeatedly by turning on cycle mode and feeding it a continuous gate signal.

4ms Pingable Envelope Generator Eurorack Module Features:

  • Unique dual envelope generator in a 20HP x 26mm Eurorack module
  • Envelope generators function independently from one another
  • Both envelopes include separate "ping" trigger-based clocking and timing controls
  • Set the voltage scale and envelope shape (skew and curve) separately for either envelope
  • CV inputs let you control the time division, skew, and curve settings remotely
  • 0 to +5V envelope output, gate outputs, and OR output available in addition to main envelope outs
  • Various cycling and triggering options let you fire off envelopes in creative ways

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.

Offer applies only to single-receipt qualifying purchases. No interest will be charged on the promo balance if you pay it off, in full, within the promo period. If you do not, interest will be charged on the promo balance from the purchase date. The required minimum monthly payments may or may not pay off the promo balance before the end of the promo period, depending on purchase amount, promo length and payment allocation. Regular account terms apply to non-promo purchases and, after promo period ends, to the promo balance. 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.
