This video is excellent. What are the Tape Speed parameters controlling? Max samplers? ER-301? w/?
@sellanraa, I hope she’s okay!
As a side note, you can skip Max and use Gibberwocky to hit something like Hermod, Shuttle Control, Yarns, etc. directly using WebMIDI: http://gibberwocky.cc/midi/
(But yes, Max would be the way to go for generating envelopes, CVs, and whatnot)
@Taubaland, the NLC systems are not known for subtlety 
That being said, Feague and Sloths will be your best bets. Filter the dual oscs (or Bong0 sequenced with, say, 8-bit Cipher) using Fk1t and modulate the various parameters. Feague will give you quadrature modulation so that the parameters move at the same rates in different directions. Sloths will give you very subtle modulations that are perfect for drones. DelayNoMore is excellent for adding some grit to a track. I ran an extremely basic LPG percussion pattern through one to make this track: https://soundcloud.com/the-february-thaw/resolutions
