Today's Patch Tip aims to overcome the limitations of the simple ADSR envelope when used to open a filter or VCA. I often find that in addition to controlling the time it takes for an envelope to reach it's peak value, I also want to control the level of that stage. This is especially true of the attack portion when I want more 'bite' without increasing the overall modulation depth of the D, S & R stages. Mixing an ADSR with an AD envelope solves this problem:
envmix1.mp3
Cwejman VCO-2RM (+ sub ex A-160) > Borg filter, ADSR-VC2 + Bananalogue VCS > Fonitronik polarizing mixer > Borg. Gate to both envelopes. Pitch CV > VCOs + Borg 'key in'. Makenoise Pressure Points row 1 offsets pitch of oscillator 2, row 2 > VCS VC rise.
This is a simple but effective solution without getting into the complexities of patching-up a time/ level envelope as found on the Korg Poly 800 or Roland JD-800. If you did, however, want to try this, the Maths, Brains/ Pressure Points and Doepfer A-143-1 manuals all offer examples.
