Detailed Description

wavetable envelope class

class

A wavetable envelope produces sample values by scanning through a stored wavetable.
The wavetable can be scanned at arbitrary speeds.
The unit creates samples either by truncating or interpolating values from the wavetable.
The unit can act either as an input unit or as a process unit.
When acting as an input unit, it directly sends out the values from the wavetable.
When acting as a process unit, it multiplies the sample values it receives at it's input port by the wavetable values.
In order to apply envelopes, the envelopes need to be triggered.
Triggering can either happen via an event based switch port ("play") or by conntinuous control of a control port("trigger").
These two methods are mutually exclusive.
The event based triggering system is inactive when the trigger control port is connected to a unit or
when this unit is in looping mode.
The envelope is triggered by sending a 1.0 value to the play switch port.
Once the envelope played in this mode, the unit turns itself automatically off.
It turns on again when it receives the next event.
In continuous mode the envelope is typically triggered by the output of a pulse unit, which is connected to the trigger control port.
Depending on this unit's settings, the envelope gets triggered whenever the values at the trigger control port
change from a negative or zero value to a positive value or whenever the trigger control port values are positive.
In this mode, the unit never turns off automatically.
Envelope control via control port is sample accurate.
Envelope control via switch port happens only at the beginning of a new process call.
This unit can be configured in the following ways: Looping can be turned on or off via the "looping" switch port.
When looping is on, envelopes get triggered again and again right after each other as long as the trigger control port delivers positive values
When looping is off, envelopes get only triggered when the trigger control port values change from negative (or zero) to positive.
Blocking can be turned on or off via the "blocking" switch port.
When blocking is on, an envelope can only be triggered again when the envelope has completely finished playing.
When blocking is off, an envelope can always be triggered. This can of course cause discontinuities.


Issues: The behavior of this unit is different when in switch port controlled event mode than in control port controlled continuous mode.
When the unit is event controlled, it sends out zero values whenever an enevelope is not playing.
This is the standard behavior of units. which are inactive.
In continuous mode, it sends out the last wavetable value * sample values arriving at the input port.
For this reason, the unit doesn't necessarily procude zero values when envelopes are not triggered.
