DUAL ENV is a dual envelope generator. It creates two different envelope slopes that can be clocked and linked together. For example, often one envelope is used for volume/amplitude and the second to modulate signals.
The envelope has five stages:
Attack two-way switch for Keyboard or seq./drum machine called Gate or Trig.
Release - sets decay time of the gate
Traditional ADSR - very static decay pitch
Second Decay knob
‘Break level’ is a secondary sustain level
Modulated with CV - look at an envelope as a wave generator
Release time modulation
Sample and Hold - receives a trigger pulse to measure to input level - also changes the statistics of what is happening - making it independent of the pitch that it is sampling
Interference Pattern to modulate the times of the parameters of the envelope generator
Low LFO frequency overlapping the sample and hold to creates a ‘swing’ effect
Sample and hold normalised to filter modulation
Q: Is the normalisation the same on the Twin Peak as the ‘Dual Env’? - use a plug to normalise -
Disconnect the sample and hold input
The Sample and hold can be clocked with an audio signal by plugging an oscillator audio output into the gate input of sample and hold
Example of using the audio output of an oscillator to clock the sample and hold of the Dual Env.
Example - to modulate 1v oct input using a triangle wave in VCA output to 1v oct
