Audiophile Circuits League ENVELOPE X3
Width 21 HP
The ACL Envelope X3 provides three classic ADSR envelopes for controlling VCAs, VCFs, and other modules. We modelled the envelopes on those of the acclaimed Roland 100M modular synthesiser, which are renowned for their punch. As ever, we wanted to add something extra, and so shortened the envelope time parameters even further – thus, our truly lightning-fast responses make Envelope X3 particularly excellent for drums, bass, and other sounds that benefit from fast and tight envelopes. But fear not, it is not a one trick pony, offering both Long and Short modes, with those ranges overlapping, making it perfectly suited to pads, drones, and similar sounds too.
On a feature level, each envelope features independent gate inputs and one non-inverted and one inverted buffered output each. Gate 1 is normalised* to all three envelopes, allowing one gate input to power three envelope generators simultaneously.
All components feature very low temperature drift, irrespective of the environment temperature or component age, ensuring high stability and repeatability. In short, whether on stage or in the studio, you can be sure that any sounds you shape with the Envelope X3 will sound as consistent over a time frame of years as they do on a scale of milliseconds.
