Yep, you can get the free demo of StrangeFlow’s Authentic Electro Samples VOL 4 over at this page here. They’re always free.
If you enjoy them, feel free to check out the full version of that sample package, which, when all is said and done, is pretty goddamn huge. Over 100 samples of royalty-free electro swing samples! (the whole thing is huge) You can look around, but I doubt you’ll find anything quite like this offer.. (Seriously, you can check for yourself :) )
If you want to check out the full package, you can do so here!
