That's clear, I know the preset concept from plug-ins in DAWs like Ableotn Live or Logic. It would be very confusing when I overwrite an existing preset and the values would be changed in all instances that were called up with this preset in the past. But when I save a plug-in preset in Ableton Live, Live shows me the name of the preset that the current values of the instance are based on, so that I can decide if I want to overwrite this preset or create a new one.
I hope you understand my point - I'm afraid to overwrite a wrong preset when I don't know which preset was the "starting point" for the instance. On the other hand I don't want to create thousands of presets, just because of not knowing which one can be overwritten.
