Hi, if I have a patch that contains [list], is there anything that I can substitute it with, that does exactly the same thing?

I've been having quite a bit of fun with the rj library (https://puredata.info/downloads/rjlib), but have found some patches like u_highpassq contain the use of [list] inside them. Normally this wouldn't be a problem, but I kind of need to be able to compile my patch using the heavy compiler (https://github.com/enzienaudio/hvcc), and the heavy compiler does not support [list] for some strange reason.

The reason I kind of need to use the heavy compiler is because that's what https://www.rebeltech.org/patch-library/ uses. I have one of their devices, and I want to load a patch onto it that contains the high pass filter mentioned previously.

Alternatively, if anyone knows of a good vanilla (not extended) resonant low pass / resonant high pass filter patch that I could use instead of the rj one then that'd be great. I'm surprised pd doesn't have something like this in vanilla by default. Thanks

@dxinteractive [vcf~] might give you the filters with a bit of extra work for highpass.
[pack] might be useable instead of [list]...... but is it the list selector that is unrecognised?
Even a raw message like [1 2 3( ....... that is a list, has the list selector added in Pd.

Hi, thanks for the reply. I passed on [vcf~] as it didn't have the sound I was after, it doesn't quite sound like a typical 12db/Oct resonant low pass filter to my ears, at least at higher cut off frequencies, and didn't think it was worth trying to wrangle a highpass filter out of it.

The heavy library can definitely do normal lists like [1 2 3( , it's specifically the [list] object that it doesn't like. In the patch in question, [list] has no arguments. Since posting this, I found http://write.flossmanuals.net/pure-data/lists/, and it says that [list] simply prepends a "list" symbol to any list it receives. If that's true then perhaps I can just do the same manually.

I have no idea why heavy does not have the [list] object, it's a strange omission / limitation

@dxinteractive There are a few objects that add an extra list tag. It can be removed with [list trim] but of course if heavy doesn't like [list] then that might not work.
But [route list] will also remove it..... sending on the list without the extra tag on its left outlet.
David.

@dxinteractive Yes, in u_highpassq.pd [list] is used to store a list for later usage:

You can replace it with a message that is overwritten with the [set( directive like that:

This should work especially if all entries in the list are numbers. If symbols are involved, some care must be taken. This only works if the length of the list is fixed.

Otherwise, if set is not supported by heavy, you could something like this:

Or even

Awesome, thanks so much for your help, especially showing a few alternatives on the exact file I want to change! I'll give all this a go. Hope it works. I really like the rj library and I'm keen to keep using it.
