Hey! Thanks for giving Dunes a spin
Re. softcut, Dunes starts up with the delay (i.e. softcut) level set to 0 by default. To turn it up, head to the params menu (you can also adjust feedback here as well).
Once you’ve turned the delay parameter up, head back into Dunes and put a couple of 2 and 4 commands in your sequence – these will multiply and divide softcut’s rate, which should be noticeable.
Let me know how it goes!
