If the current node has no children you can delete the node. You can add a new node as “child” of this node. This controls the node’s basic behaviour: you can set its natural pulse frequency (a multiple of the base tempo”) via “Rate” or “fine tune”. Node Menu (right click on node) Tab 1 - Node menu If you move nodes far enough apart, or turn the signal strength to 0, the arrow will turn into a pale dotted line: no signal is being sent, so the nodes are not affecting each other.Again, as signals get stronger, the arrows get fatter and more orange. Moving nodes further away weakens the connection.
Moving nodes closer together means the connection is stronger: more signal gets to the destination just like if you walk closer to a speaker, it gets louder. But weaker signals, and multiple connections can mean the synchronisation becomes more complicated and more interesting rhythms are created. Nodes try to synchronise to the incoming signal (a process called “entrainment”). The more signal gets to a node, the more it is affected by the signal. Right click on a connection to control the basic strength of a connection (like turning up the power on its transmitter) (you will see the arrow grow fatter and more orange).Right click on a node to open its control menu (see NODE MENU BELOW).The root node is the largest double-ring node - this defines the base tempo for the whole system, and sets the pulse for the quantiser system.
Each circle on screen is a node in the network. There is a basic guide below, and this video may also be helpful You might want to begin by clicking the cog icon on the top right, and loading a preset, then playing around. The GUI sends OSC messages to max, and the patch interprets them, sends them to the cpg.network~ object, and uses the output signals to trigger sounds. To use neurythmic, first load the max patch and switch on DSP in MAX, then load the GUI: NeurythmicGUI.exe. In the “gui” subfolder you will find an executable “NeurythmicGUI.exe”.Īt present the GUI only works on Windows, but even for macOS users the MAX patch is a good starting point for working with my cpg.network~ object, and developing alternative interfaces: whether that’s a simple gui, some kind of algorithmic control system, or a physical installation. Inside the NeurythmicApp folder in the MAX package, there is a max patch “neurythmic.maxpat”. The MAX package includes a MAX/MSP port and update of Neurythmic - a rhythm sequencer/ drum machine/ rhythm generator built on Central Pattern Generators. The CPG objects for max are documented in the usual fashion, with help patches inside MAX/MSP, below is a quick intro to the neurythmic patch and GUI. The package comprises three objects and a hackable MAX/MSP implementation of my CPG sequencer/ rhythm generator Neurythmic, including a standalone GUI application. No building is required: just download the repository and put it in your MAX packages folder. For an intro to CPGs see this page or my paper here.ĭownload the MAX/MSP package from GitHub. This page documents a set of externals which allow people to explore the use of Central Pattern Generator (CPG) neural networks. I’ll try to add explanatory images and maybe a tutorial video in the coming weeks Note - this is currently under construction.
