i’ve been searching and experimenting, and it seems that:br

  • a white noise should be used beside of another wave type (probably a saw?)br
  • volume (or cutoff?) should be modulated by an LFObr
    br
    but i don’t know how to get that soft and kinda thin sounding with that specific timbre… any ideas?br
    br
    br
    thanks!br
