with the gate setting in before the release stage has completed, interesting rhythmic effects can arise.
#AUDULUS OSCILLOSCOPE MODULE GENERATOR#
With the attack time set to longer than the clock rate the envelope generator can suddenly starts to function as a kind of clock divider, as Hordijk points out in his NOVARS tutorial video. It’s a simple feature that opens up a number of possibilities. This means that a short trigger can result in a long attack swell, or a short attack can be triggered with a broad gate. the attack time of the envelope is independent of the gate time. In this first small patch I’ve adapted some of Stephen Schoen’s uLope modules to include a trigger mode – i.e. Hordijk mentions in one of his videos that designing an envelope generator is perhaps the most difficult of all the modules in that there are so many possibilities to consider, and that certainly rings true as I’ve begun to explore it.
I’ve made a small start on putting together an Audulus version of the Hordijk Dual Envelope generator. The patch can be found on the Audulus forum. Hordijk provides a nice explanation of this technique in one of his NOVARS tutorial videos. Since modulation is most effective when the pitch of the modulating waveform is lower than the one being modulated, a sample & hold has been included. The resulting shapes are perhaps most easily understood by taking a look at the diagrams in Hordijk’s schematic.Įach stage also has a modulation input that adds to the values set by the knobs. The second decay is also preceded by a break setting that adjusts how far the first decay falls. With the decay knob turned all the way up, a conventional flat sustain can be achieved. One of the innovations in his design lies in replacing the sustain section with second decay stage that can slowly taper off, thus allowing for more ‘natural’ sounding contours.
I’ve packed the modified uLope sub-stages into a module that more closely resembles the ADBDR envelope in Hordijk’s Dual Envelope generator.
