A MIDI controller or control surface can be used in write, latch or touch mode to create FX parameter envelopes:
- Within the plug-in window, click on the parameter, then on Param then on Learn . Tweak the button, knob, or fader on the control device. A confirmation message appears in the Command field. 2. Select a CC mode: usually this will be absolute or one of the relative options. Consult the device's documentation: if in doubt, try Absolute to begin with. For smoother operation, choose Soft takeover. Toggle mode is also available: this allows FX parameters to be toggled on/off with a single mapping. Optionally, select Enable only when effect configuration is focussed. This allows you to assign the same control to another parameter in a different plug-in. 3. When the MIDI/OSC Learn dialog box is shown, tweak the control on the external device, select the option Arm envelope for selected parameter and click on OK. The envelope will be displayed. You can use the control device to write changes to the envelope during project playback (see section 18.5). In Trim/Read mode you can use the control device to manually adjust the parameter.
