Envelope Destination
Once an envelope has been created, it's a good idea to set its generic type
using the Envelope Destination popup menu. This menu sets the parameter
type that the envelope modulates. Available destinations include Amplitude,
Amplitude Mult., Mix Level, Mix Level Mult., Panning, Pitch, Frequency,
Phase, Cutoff and Resonance. Note that setting the Envelope Destination
does not assign the envelope to a specific destination.
Each envelope type is designed to modulate only one specific destination.
Some envelopes are designed for oscillators, some for filters and others for
the sampler. Some are designed for any destination. The following list
describes the recommended use of envelope types:
Amplitude: This envelope is designed to be used with Oscillators and
the Sampler. The envelope value is multiplied by the corresponding
value in the Envelope Matrix and then summed with the Oscillator or
Sampler amplitude. It is NOT designed to modulate Filters.
Amplitude (Multiplication): This envelope is similar to the previous one
however in this case the envelope value is multiplied with the Oscillator
or Sampler amplitude.
Mix Level, Mix multiplication: These envelopes are similar to the
Amplitude envelope, but they can also be used for Oscillator and Filter
modulation. These envelope types cannot be used to modulate the
Sampler (because it doesn't have a general mix level parameter). To
modulate the Sampler use an Amplitude envelope instead.
Panning: This envelope is designed for modulating Oscillators and
Filters. This envelope is additive.
Pitch, Frequency, Phase: These envelopes are designed for modulating
Oscillators (but not Filters). These envelopes are additive. Pitch is in
Semitones and Frequency in 100Hz.
Cutoff and Resonance: These envelopes are designed only for use with
filters.
All envelopes output values in the range 0.0 to 1.0 (if the +- switch is set to
Unipolar) or -1.0 to +1.0 (if the +- switch is set to Bipolar). An additional
multiplier value is available in the Envelope Matrix to set the envelope
values to an appropriate range. Further details of these values are found in
the Envelope Matrix section of this manual.
The difference between Amplitude and Amplitude Mult (Multiply) is as
follows: If the Amplitude envelope is sent to an Oscillator, the value of the
Amplitude envelope is added to the oscillator amplitude. For example, if the
