1. The Patch Mutator is a floater in the editor just like the Virtual Keyboard and the Parameter Pages It can be opened or closed by selecting Patch Mutator on the Tools menu Shortcut Ctrl 2 With the Patch Mutator floater open you can still edit the patch as usual add or delete modules or turn the knobs The Patch Mutator float consists of five different regions From top to bottom e Various settings and action buttons for the different breeding operations that generate new children Mutate Randomize Interpolate and Cross See the Patch Mutator Reference section below for a detailed explanation e A row of boxes representing the parent and children sounds Each box contains a chromosome graph The shape of this curvy line is derived from the actual parameter values The chromosomes show at a glance how different the variations are In the screenshot above the children are clearly quite similar while the sounds in the temporary storage look completely different from each other e The Temporary Storage which serves as a scratch pad during the evolutionary process You can save sounds you like by dragging them to a box in the storage and later you can drag them from the storage to one of the parent boxes in the row above to continue breeding A row from the Temporary Storage can quickly be transferred to the eight patch variation buffers by clicking on the v button to the right of the row Click the x button to clear t2. This can be the case with FM synthesis and other synthesis techniques where the internal relationship between the parameters is crucial Since it uses only safe values there is a good chance that the children will be good Try mating two nice Patch Variations to produce more nice and well behaved variations You can also try to mate a nice sound with a weird random sound to induce some new life into too well behaved variations Mating siblings two sounds from the same set of children usually doesn t work well Usually siblings are already genetically quite similar so the resulting sounds will not exhibit much interesting variation Shortcuts While holding Ctrl on the computer keyboard drag and drop one sound on another to perform a Crossover from those two sounds You can also perform a Crossover operation without using the mouse With the Patch Mutator active select a variation you want to use as parent Then copy it to a parent box with the O key Mother or the T key Father on the computer keyboard With the parents in place press X to perform the crossover The Temporary Storage With the Patch Mutator it is easy to produce a vast number of sounds and often one doesn t know until later which sounds should be kept Temporary results and unexpected sounds can be stored in the Temporary Storage to be reused later in the breeding process To save any sound parent child or variation in the Temporary Storage dra

9. The Patch Mutator and the Patch Adjustor Since the OS version 1 4 the Nord Modular G2 Editor provides two new tools for patch modification the Patch Adjustor for quick patch changes on a global level and the Patch Mutator for extensive sonic exploration based on interactive evolution Together these tools greatly simplify the sound design process and allow you to get interesting results even without knowledge of the inner workings of a specific patch The Patch Adjustor Quick Patch Adjustment x OAAOO A2OO Attack Decay Sustain Release Mod Rate Timbre Resonance Effects The Patch Adjustor contains a number of knobs for quick adjustment of all parameters of a certain category such as all attack times or all resonances In this way you can quickly shape a sound in a more general way without knowing the specifics of the patch For example turning the Attack knob to the left will decrease all attack times in the patch relative to their current position Turning the Timbre knob will adjust filter frequencies FM amounts shapers and some other parameters that affect the timbre of the sound If the result is not what you expected just turn the knob back to its middle position or click the centre marker As soon as you move the focus to another variation or add or remove a module the changes will be permanently applied and the knobs will return to their middle positions When browsing a large number of patches or when evolving
