Worklet Improvents / fixes

[daslyfe]

These are fixes for the shape/crush/coarse worklets

• all are now stereo fx
• shape now has an optional "postgain" param when using array syntax: "shape("8:.5")"
• coarse works predictably on non chromium
• coarse and crush fx no longer go silent when inputting 0
• Added a distort worklet, which is the same as shape but with a much safer/gradual input curve

nice! is the shape range now very different / would this change existing patterns using shape audibly?

yes before 0 -.8 was the usable range. Now it is 0-10 and the exponential curve of the shape param input is different/more predictable. my experience with the prior curve would be that you can carefully adjust it to .8ish or so, but once you hit .9-1 it would blow up your speakers which is very bad for live improvising

yep shape is dangerous :D I just worry about the breaking change, so maybe find a new name and keep the existing shape as is? iirc the shape of tidal also has a range between 0 and 1 with a similar explosive behavior.
not sure if i like the range between 0 and 10 because it does not play as well with normalized values.

I adjusted it so 0 - 1 goes from not distorted to very distorted in a linear fashion. if you want to be more extreme you can continue to go above 1. Would that be a decent compromise? It could still affect the sound of patterns that use shape slightly but it makes the function a lot more useful imo. I can also create another version called shape2 or something like that :)

I think a somewhat-breaking change like this is justifed here to protect people's ears (especially in a live setting)

I also agree that a more linear distortion curve is very desirable, it might still make sense to add it as an alias because it changes the mix of a lot of existing stuff + keeping parity with tidal is generally a good thing. Maybe just call it distort or shapelin (or both) ?

Okay I updated it and added another processor to keep shape behavior the same. New processor is called distort, but has a shorthand of dist. It has a much more gradual and predictable curve

[felixroos]

there is a built in way to define controls that may be an array:

export const { shape } = registerControl(['shape','postgain']);

this will automatically define shape and postgain in the hap value when ":" notation is used, so this should be enough:

shape !== undefined && chain.push(getWorklet(ac, 'shape-processor', { shape, postgain }));

same can be done for distortion

[daslyfe]

cool, I updated it but instead of using "postgain" I used shapevol and distortvol because postgain is already the name of a different control.

this is ready to go again
