for drum in chorus i used Kontakt Native Instruments - Studio Drummer for drum in verse i used battery 4 with Miami Vice kit, and also random drum loop from Slate Digital sample pack with low cut filter and distortion for melodies i used vst called Astra, which I advise you if you do not use it for bass guitar i use EZbass also i used nexus for other sounds and korg triton vst, but i could use anything, I needed pretty standard sounds
