Envelope Section
Envelope generators are used to control several important sound parameters in analog synthesizers, such as pitch,
volume, filter frequency etc. Envelopes govern how these parameters should respond over time - from the moment a
note is struck to the moment it is released.
Standard synthesizer envelope generators have four parameters; Attack, Decay, Sustain and Release (ADSR).
There are two envelope generators in the NN-19, one for volume, and one for the filter frequency.
! Please refer to the Subtractor chapter for a description of the basic envelope parameters.
Amplitude Envelope
The Amp Envelope is used to adjust how the volume of the sound should change from the time you press a key until
the key is released. By setting up a volume envelope you sculpt the sound’s basic shape with the four Amplitude En-
velope parameters, Attack, Decay, Sustain and Release. This determines the basic character of the sound (soft, long,
short etc.). The Level parameter acts as a general volume control for the sample patch.
Filter Envelope
The Filter Envelope can be used to control two parameters; filter frequency and sample pitch. By setting up a filter
envelope you control the how the filter frequency and/or the sample pitch should change over time with the four Fil-
ter Envelope parameters, Attack, Decay, Sustain and Release.
Filter Envelope Amount
This parameter determines to what degree the filter will be affected by the Filter Envelope. Raising this knob’s value
creates more drastic results. The Envelope Amount parameter and the set filter frequency are related. If the Filter
Freq slider is set to around the middle, this means that the moment you press a key the filter is already halfway open.
The set Filter Envelope will then open the filter further from this point. The Filter Envelope Amount setting affects
how much further the filter will open.
