System X ADSR


Eurorack’s snappiest envelope, converted to MU!


Due to supply chain issues with MU panels, your order will not be fulfilled immediately. We are currently taking pre-orders for panel variants of this product.

System X Envelope is our bestseller, so we made a MU version!

Chances are, your mailman is really digging on these envelopes. Based on the Roland 100m ADSR, but we made it snappier. Accept no imitations, this is the genuine bootlegged lookalike moonshine clone.

“I received my System X Envelopes on Friday, just tried them out this weekend, they are without a doubt the best envelopes I’ve ever used.”
“I am telling you Rick, best envelopes in Eurorack by a bloody long mile!”
“I just got the FC System X Envelopes in this afternoon. I’m pretty much in love with them.”
“The System X Envelopes are super snappy and responsive, maybe the most of any Euro
ADSR I’ve played yet.”
“It kills other ADSR’s then dresses inappropriately at their funerals.”
“They kick ass!”
