Envelopes
=========


Construction
------------

- :doc:`Envelopes (basic) <tutorial_12_envelopes_basic>` — Create and plot two simple envelopes, one with evenly-spaced linear segments, and one with uneven, curved segments.
- :doc:`Envelopes (advanced) <tutorial_13_envelopes_advanced>` — A more comprehensive list of ways to construct and modify Envelopes.


As note parameters
------------------

- :doc:`Glissando from Envelope <tutorial_14_gliss_from_envelope>` — Plays a glissando by passing an Envelope to the pitch parameter of play_note.
- :doc:`Envelope Shorthand <tutorial_15_envelope_shorthand>` — Plays two glissandi by passing lists instead of envelopes to the pitch argument of play_note.
- :doc:`Volume Envelope <tutorial_17_volume_envelope>` — Plots an envelope representing a forte-piano-crescendo dynamic, and then uses it to affect the dynamics of a note's playback.


As compositional parameters
---------------------------

- :doc:`Evolving Form <composition_form_larger_scale_form_evolving_form>` — A piece for cello, pianoteq (MIDI), and SuperCollider (OSC), shaped by envelope-driven formal parameters. *(needs scamp_extensions)*
- :doc:`TimeVaryingParameter Extension <composition_form_larger_scale_form_time_varying_parameter_example>` — A script using the context-sensitive :class:`~expenvelope.envelope.Envelope` wrapper :class:`TimeVaryingParameter`, which reads into the underlying envelope at the current clock   's beat or time when called. *(needs scamp_extensions)*
