Comes with full installation Xfer Records Serum 1.2.1 + update files.
Please read the readme.txt file inside before installation.
Ps Soundtoys 5 I uploaded recently has to be used in effects folder only forgot to mention.
Also you need to install Soundtoys 4 or below for no issues they work perfectly on newer Virtual Instrument Hosts such as FL Studio 20.2 and above and Ableton.
You can source that somewhere else
