When you click on a download button on this website a .voltagepreset file will be downloaded to your computer.
You then need to open the file to get Voltage Modular to recognize the preset as there is no “import preset” function.
Opening a .voltagepreset file should automatically launch the standalone version of Voltage Modular with the following dialog…
Here you can change the category or name or just click on Cancel if you want to try out the patch without commiting to saving it yet.
Alternatively you can launch Voltage Modular first and then open a .voltagepreset file.
If you are running Windows and have Version 2.7.0 of Voltage Modular installed then use this second method otherwise the load fails leaving you with empty cabinets. This should be fixed in the next update of Voltage Modular.
