My similar problems with Padshop Pro and Zero Gravity installation
THREE weeks since I raised a Support ticket for similar Padshop Pro & Zero Gravity installer problems and still no response from Steinberg. (In comparison, I raised a ticket with NI for one of their products and got a response and resolution within hours)
Bearing in mind the number of queries about this, I suspect something is seriously wrong with the Padshop Pro installer and also the PadShop Pro & Zero Gravity installer. Great to pay for something and get no response from the vendor. Not great Steinberg, not great.
Padshop Pro & Zero Gravity issues:
I updated from Padshop to Padshop Pro with Zero Gravity soundset bundle and the soundset was not visible after installation in Padshop itself (only Padshop and Padshop Pro presets were displayed)
I located the vstsound file ADD_SMT_118_Zero_Gravity.vstsound
This was installed to Roaming\Steinberg\Content\Padshop. Note: I also copied the file over to Roaming\Steinberg\Content\VST Sound , just in case Padshop was looking at that location for the file.
Still the Zero Gravity presets were not showing in Padshop Pro.
I then noticed that the file is named with prefix: ADD_SMT_118_Zero_Gravity.vstsound. However, all other SMT files are named: FCP_SMT (ie: do not start with ADD).
I decided to rename the prefix to FCP_SMT_118_Zero_Gravity.vstsound.
As a result of this action the actual Zero Gravity audio samples are recognised in Media Bay, but only as Zero Gravity audio sample pack. There are still no Zero Gravity presets available in Padshop Pro.
