chop vex context
Define a custom CHOP operator with a program that edits channel values.
The CHOP context allows users to change values of channels in a CHOP. Each CHOP function works on a single sample of a single channel of a CHOP.
Globals
| SR (read-only) | Sample rate for the channel. |
| S (read-only) | Index of the start of the current channel. This is the index of the first sample. |
| NC (read-only) | Total number of channels the CHOP will affect. |
| I (read-only) | Index or sample number of the current channel. |
| C (read-only) | Channel number for the current channel. When processing multiple channels, this is the index of the channel currently being evaluated. |
| L (read-only) | Length of the channel (total number of samples). |
| V | value of the current sample. This variable should be set to the new value by the function. The variable is initialized to the value of the first input’s channels. |
| E (read-only) | Index of the last sample (end sample). |
