Chapter 24 Sculpture 447
The Envelope can now be recorded. We assume that your MIDI keyboard has a modula-
tion wheel which outputs the corresponding MIDI controller message (CC number 1)
and that option 1 ModWh is selected for control of Envelope 1 (CtrlEnv 1) in the dark
bottom edge of the Sculpture window.
4 Click on the button labeled R, located in the upper right corner of the Envelope section
below “Record Trigger”, to prepare the Envelope for recording. Select the Note+Ctrl
option for the recording. This option specifies that the recording of the controller mes-
sages from the modulation wheel will begin the instant the first note is played.
5 Play a note when you want to start the recording, and move the modulation wheel
slowly upwards while keeping the key on the keyboard depressed. Pay attention to the
sound variations you create while moving the modulation wheel.
6 At the end of the recording, return the wheel to its initial starting position and, after
you’ve released the depressed note, click on the “R” button to deactivate the recording
mode.
You can now see the curve you recorded in the graphic display. You’ll note that the
curve arches exclusively above the zero axis—this is no surprise as the modulation
wheel only sends unipolar values, which means between zero and up to a positive
maximum value. As we already moved the Object 1 slider all the way to the left end of
the string, it can only be shifted all the way to the right by the Envelope when the
maximum modulation intensity is reached.
Play a note, or better yet, an entire chord and listen to the modulation you recorded. If
you’re not satisfied, you can, of course, repeat the procedure described above as often
as you’d like. The maximum available recording time is 40 seconds. It is therefore possi-
ble, if you’d like, to control parameters and create modulations that extend far beyond
the well-worn path of a simple ADSR envelope progression.
Note: By moving the junction points, you can edit the shape of the envelope when the
need arises. By clicking in the empty part of the graphic display and moving the mouse
to the right or left, you can zoom in and out of the display. When you activate the small
Sync button, the junction points snap to a rhythmic grid (further information about
these parameters and their functions can be found on page 397).
