Download setup files and read the manual for the GeoSynth Euorack module, an itterative geometric synthesizer based on Processing.
For Mac OS X you can download the compiled apps, they are standalone apps that do not require to have Processing installed. the patch can not be modified so if you want the un-compiled version download setup files.
Please do not feed the GeometrySynth with incoming voltage above 10v , if you do so you may kill it ! We do understand that this will be a really sad situation so contact us if that happens, as we may be able to send you a new heart for your GeometrySynth. Read the manuel, it's full of info and definitely help you getting started.
