1. First steps in Reaktor Core - Native Instruments

For example, for the above table of 5 elements we will need to specify the
float data type and the size of 5.
Please note that because array indices in Reaktor Core are zero-based,
the index range for an array of size 5 would be 0 to 4 (you can also see
it in the table above).
Array OBC signals corresponding to different item data types are, of
course, not compatible.
To address an array element you need to specify an index, which you can do
using an Index module (Built-In Module > Memory > Index):
The master OBC input (bottom) of the Index module should be connected
to the slave output of an array module. The master input connection type
should match the array type, the former can be specified in the properties
of the Index module:
