LinPlug Octopus - Manual (Page 13)

least one Oscillator is switched on, otherwise the module will not produce
any output.
The parameters for each Oscillator can be set in the instrument's Oscillator
module. This module is described in the Oscillator section of this manual.
Destinations
The destination for each Oscillator is located from left-to-right across the
Matrix. Each Oscillator can be sent to Oscillators 1 to 8, the inputs of the 2
Filters and the output mix. The output from each Filter can also be routed
back to any or all of these destinations.
Nodes
The amount of signal sent to a particular destination is determined by the
setting of the Matrix node. This can range from -1.0 to +1.0. When the
signal level is set to 0.0 the node is deactivated.
One of the key features of the Octopus is that its Oscillator Matrix can be
used to produce FM (Frequency Modulation) synthesis. See the Quickstart
section of this manual for a simple example of how to create an FM patch.
