When we talk about envelopes we usually are boasting about how fast and snappy they can get, what the shapes do to the sound, and what modules they should control, but an equally important topic is how slow they can go. Many envelopes have a fixed time range. So even if they have the ability to go really fast and really slow, dialing in the perfect length can be hard because of all of that range. Javelin has three ranges, so its easy to dial in whatever you're going for and if the longest range isn't enough, you can add CV to make it go even slower.
In this video, Alex runs us through a patch he already created using the WMD Javelin ADSR Envelope / VCA eurorack module to control the overall intensity of the sounds coming out. He uses CV a CV offset from WMD 4tten into the Attack and Release inputs on Javelin to extend the overall time to about 2 minutes per stage. With 5 volts of CV, Javelin is capable of creating envelopes with each stage maxing out at 88 minutes! That seemed a bit much for this video but a 4+ minute envelope signal is still pretty good.
The Envelope signal in this patch is routed all over the system using mults. It controls volume, filter cutoff, an LFO's speed, and eventually a comparator sends a gate to Fracture, adding another voice and increasing the chaos.
This patch is just one example of what a long envelope signal can be used for.
