CabbageGetValue

This opcode queries the current value of a widget. It can run at init-time or k-time and includes an optional output argument that triggers a value of 1 for one k-cycle whenever the widget value is updated or changed.

Syntax

kValue cabbageGetValue SChannel

iValue cabbageGetValue SChannel

kValue [, kTrig] cabbageGetValue SChannel

Initialization

• SChannel – the name of the channel to query
• iValue - the current value of the widget at i-time

Performance

• kValue - the current value of the widget at k-time
• kTrig - a trigger signal that will return 1 for a single k-cycle whenever the value has been updated/changed

Example:

<Cabbage>[
    {"type":"form","caption":"Simple Instrument","size":{"width":1000,"height":520},"pluginId":"RMSy"},
    {"type":"rotarySlider", "channel":"gain", "bounds":{"left":150, "top":10, "width":100, "height":100}, "range":{"min":0, "max":2, "value":1, "skew":1, "increment":0.1}, "text":"Gain"},
