How would you recreate this bass sounds?
I wonder how he can get that wavy effect.
LFO! Low Frequency Oscillator. I don't know what synth you're using so I can't help you on the process of getting the LFO working with your bass sound. You will need to use the LFO on your cut-off filter, it can usually be synced with the tempo of the song.
Here is a really simple video that shows the effect of the LFO:
Listen to it at 2:20, you can hear the 'wavy' effect it creates.
Hope this helps!
I would say that, you can recreate this with any Massive "Bass" preset and playing notes around -2 or -3 octaves, and the waviness is caused by sidechain compression. Glide? Maybe, but i wouldn't say that so easily. More like an envelope with a long release.
(maybe you already got it "since january") ;)
