Array Get

Array Get reads the element at the specified Index from the incoming array. The index is zero-based: 0 is the first element, 1 is the second, and so on.

Negative indices wrap from the end: -1 returns the last element, -2 returns the second-to-last. If the index is out of bounds, the Element output will be empty (no value).

The node also outputs convenience values — Count (total number of elements), First and Last elements, and Is Empty (true when the array has zero elements).

• Accessing specific channels: After splitting EEG data into an array, use Array Get to extract a specific electrode channel by index.
• Peeking at boundaries: Use the First and Last outputs to monitor the newest and oldest values in a rolling data buffer.
• Conditional logic: Connect Is Empty to a Switch or Logic node to handle the case where no data has arrived yet.
• Indexed selection: Connect a MIDI CC or UI control to the Index input to dynamically select which array element to display or process.

• Negative indices are supported: -1 gives the last element, -2 the second-to-last, etc.
• If the array is empty, all outputs except Count (0) and Is Empty (true) will be empty.
• For extracting a range of elements instead of a single one, use Array Slice.
• Pair with Array Set to build and then read back from a dynamic collection.
