Until September 2nd, 2021, if you buy OST Audio's Amazing Serum for $24.00 you'll get Synthwave Drums and Synthwave by Alex for free.
OST Audio says:
Amazing Serum is something more than just a Serum Soundbank. Each sound generates something completely different but they have one thing in common – Retro feelings.
80 retro stylized presets for Serum (Arp, Bass, Pad, Synth) come together with 8 inspiration templates for Ableton, FL Studio, Cubase, Studio One, Logic Pro.
