Challenge - Create a Doppler Effect

I really like Mutable Instruments Warps, amongst other things the Parasite firmware introduces a Doppler effect.

Is this possible with the ER-301?

Wikipedia page to refresh my memory:

yeah i think you could pull this off with the skewed sin envelope or similar controlling the pitch of a sample player and VCA to create that… mmmmmmmmmeeeeeeeeeoooowwwwwwwwww combination of rise and fall of volume and pitched sound .

Yeah… intuitively I feel the same; I might have a read of the parasites code or chat to Matthias about it, I can’t quite get my head around it completely at the moment :slight_smile:

I hope Matthias gets an ER-301 and becomes interested in the SDK if/when that comes out. :slight_smile: His alternative firmware is great for the Xaoc Batumi and the Mutable stuff. (sorry that was slightly off topic, ha)

The Variable Delay unit is essentially using the Doppler effect simulation to change delay time smoothly.

  • Decreasing delay is equivalent to a source moving towards the listener.
  • Increasing delay is equivalent to a source moving away from the listener.

Oh, yes, of course… that makes total sense - thank you!

So it’s a question of getting the settings and modulation right, I will have a play :slight_smile:

Maybe a slight difference in phase between left/right would make an otherwise realistic modulation shape sound even more realistic in that patch…

Always finding new viable ways to embarrass myself… here we go:


The world needs more Neils.



Terrifying thoughts. Haha!

Heh. Nice one, Neil!

I do hope that car is on the way to the mechanic. :smiley_cat:

Excellent - I think I laughed more in these 7 minutes than in any of your other videos :joy_cat:

Thank you!!!

edit: just had a thought, this could work really well with your cat … “meeeeeooooooowwwwwwww”


Poll: Should Neil imitate a train, plain, or rocket ship on his next tutorial?


I call rocket ship on a train.

Neil – don’t change a thing, ever :smiley: Thanks, love the videos!

I would love to watch a stand up comedy routine, just Neil and his ER-301 on stage (OK, and maybe the cat too).
