The Experiment Vol.1 is a 40 presets freebie library for Xfer Serum.
For the design of most of its sounds there is a two sides approaching.
 
The first one is to send a usual or a custom wave to the noise Osc and then modulate some elements of the sound with this. As a result when noise pitch is to left the modulation is slower but as increasing is pitch then a faster ratio of modulation is being achieved. Experiment with the noise pitch for most of the presets to get different results.
 
The second side is that for many presets the waveforms were created with the powerful formula parser of Xfer Serum resulting in some interesting waveforms.
 
Presets were designed with Serum v1.351 and run better with this or newer edition
