Count channel node
Counts the number of times a channel crosses a trigger or release threshold.
This chop counts the number of times a channel crosses a trigger or release threshold. It operates in either static or realtime (“Cook to Current Frame”) mode.
Crossing the trigger threshold (increasing past the trigger level) creates a trigger event. Similarly, crossing the release threshold (decreasing past the release level) creates a release event. Operations may also be performed while the input remain above or below the trigger or release levels. On each event, the count may be increased or decreased by 1 or the time, or reset to zero. The time per sample varies with the sample rate (i.e. for 100 samples/second, the time for each sample would be 1/100th of a second).
The optional second input is a reset input. The first channel is interpreted as a channel containing reset pulses. Whenever this channel is non-zero, the count for all channels is reset.
This CHOP can be time sliced, and take advantage of Minimal Time Slice Cooks.
Parameters
Trigger
Release = Trigger Threshold | If on, the trigger threshold is also used as the release threshold. |
Trigger Threshold | The channel level that must be exceeded in order to trigger a count. |
Release Threshold | A release count is triggered when the channel level drops below this threshold. |
Re-Trigger Delay | The amount of time after a trigger point that a new trigger may occur. |
Trigger On | Determines whether a trigger occurs on an increasing slope or decreasing slope when passing the trigger threshold. A release will occur on the opposite slope. |
Count
Limit | The count can be clamped or looped between the limit minimum and maximum. Clamp will hold the count value at the maximum/minimum value if it goes above or below the limits. Loop will loop the count back between the limits by shifting the count to the maximum or minimum limit. |
Limit Minimum | Minimum allowed count number. |
Limit Maximum | Maximum allowed count number. |
Off To On | The operation to perform when a trigger event (off to on) occurs. |
While On | The operation to perform while the input remains triggered (on). |
On To Off | The operation to perform when a release event (on to off) occurs. |
While On | The operation to perform while the input is not triggered (off). |
Reset Count To Zero | In time slice mode, this resets the count for all channels. |
