(resolved) JSFX: provide factory-presets (linked from effect)

[geraintluff]

EDIT - you can apparently already do this using matching filenames! (Justin's answer)

---------

I would really like to include "factory presets" in my JSFX effects. Without this, it's difficult to give new users a quick impression of what your effect/synth can do.

Currently, I provide separate RPL files which have to be downloaded/imported by hand - and I have already had one person get in a mess by importing RPLs into the wrong effect.

---------

I think the best way to do this is specify an RPL file in the effect header, to be loaded from the same directory as the JSFX source (in the same way as PNG files are), like:

desc:My Effect

slider1:5<0,10,1>slider description

presets:my-effect.rpl

@init
// etc.

These effects would not be modifiable by the user, they would only change if the RPL file were changed.

VSTs already have different groups of presets, and REAPER displays them like this:

Nice idea !

+1 nice idea!

+1 This would be great for developers and users.

+1 This would help make better use of JS effects in general. Many people don't know what a lot of these effects can do and it'd be awesome to create and include them with tons of JS effects.

You can save the preset library with the name <jsfxname>.rpl, and it will be auto-imported by REAPER on plug-in load (no manual import necessary, just place it with the jsfx). The only place this is used in the stock install is remaincalm_org/paranoia_mangler.

if you make a gui you can certainly already do this. You just have to serialize the values. I've done similar in the past... I'll dig something up.


easier than that... you can do it without making a GUI.

you just need to define tables of values for each preset in @init.

Create a slider for each preset. in the @block section you make code such that the parameters changes to whichever table of values is selected when the slider changes. You do need to serialize the values I believe so that the changes are saved when you reopen the project.

I always thought "why is it these JS programmers never put at least a few presets in?!"

And now I know : )

That's fantastic!

Thanks for letting me know about this - I've added presets to my bundle, and I think it makes such a difference.

This is great! Thanks Justin.

Two things:
1) I wish more JS developers used Reapack
2) That was an easy update, thanks to Reapack

Hi, I made a solution for "preset:" lines in JSFX.
