Bespoke Unit: Curl (Wave Folder)

Introducing Curl, a wave folder for all your wave folding needs!

Nothing adds character like a wave folder, especially one like this that just keeps. on. folding. Use it to create complex waveforms out of a simple sine, add distortion to your samples, or even fancify your LFOs.

Key features:

  • Very low CPU usage (~5-10%)
  • Input gain (to enhance foldability)
  • Wet/Dry mix
  • Variable reflection point for subtle to intense folding.
  • Configurable depth to reduce CPU if necessary.



Hell ya, this is great thank you!

I noticed that the bias is not reflected on the controls, but other than that
this is super cool. Thanks!

Good point, I’ll add that shortly. In the meantime not too hard to do it manually.

Feeling quite silly, I just realized that a simple wave folder can be created using the sample scanner and a sine wave :stuck_out_tongue:

This makes wayyyy more sense than using a fixed series of folds but the naive approach loses out on the “reflection” point feature in Curl.

Needless to say, I’m going to try to make a better version of this unit using sample scanners.


Hi! Any update on this unit? I’ve yet to get my hands on an ER-301, just planning my case around it at the moment so would love to hear a sample if possible! :smiley:

It sounds very bright basically, since it effectively folds with a triangle wave. When I get back around to this I want to use tanh saturation and sin wave folding for something more characterful.

I can’t install anything bar sloop - which is beyond awesome but I dig these other modules, any eta for updating if at all?

I’ll get to them all eventually! Just started a new job so I’ve had less time to finish these off, but in a month or so I should start accumulating free time :slight_smile:
