Hi, I found some really nice looking synths ...

http://www.monologx.com/ecosystem/

https://forum.pdpatchrepo.info/topic/7981/zorg-synthesizer-v-1-1

However, frustratingly they both seem to use the [knob] gui item from "flatgui" library. Purr Data does not come with it so I installed manually, but still no knobs. So I tried it in the default Pure Data download, installing flatgui library through Help --> Find Externals ...

But still no freaking knobs. I want to twiddle my knobs!

The Pd console has a lot of ". couldn't create" messages.

Can anyone confirm the same behaviour to see if its simply something unique to me. Otherwise how do I get these patches to work ?

Cheers.

I believe I ported [mknob] but not anything from flatgui.

I'll see what kind of work is involved in porting [knob].

@Michael-Z-Freeman Would you mind checking if moonlib/mknob is a suitable drop-in replacement for flatgui/knob? Judging from the code the interfaces look very similar.

Thanks. So it was incompatible.

OK. I'll try some editing.

EDIT: Probably a bit beyond my pd experience here, but I tried replacing "knob" with "mknob" just for the volume control. No effect. I compared the mknob help (mknob-help.pd) with the syntax in "MG_-_ZORG.v.1.1\sub\VOLUME.pd" and it looks like it should work.

Make sure that you have moonlib installed (go to Help --> find externals).

Then, create the object [moonlib/mknob] and it should work.

Oops, sorry... try [moonlib/mknob]

Got a knob to show !

At least there's only one knob now in Britain (you'll only understand this if you're a Brit) ... anyway ...

So, I don't understand how to use the above syntax yet ([moonlib/mknob]). So I added moonlib path and moonlib name to end of lists in Purr Data preferences (I thought PD would just hierarchically read the entire extra directory but whatever) and just changing "knob" to "mknob" creates the control. I have not checked yet if the sound it being altered correctly, however it does respond to mouse control.

EDIT: All controls working and knobs seem to effect sound OK although I don't know what Zorg is supposed to sound like. It does not sound "right" but it just might not be what I was expecting. I'll see what happens with the other synth.

@Michael-Z-Freeman

The main question is whether "mknob" and "knob" output values in the same range.

Could someone test [knob] for me and say what the default range is? It looks to be 0-1 from the code but I'm not sure.

@jancsika in pd-extended 0.42.5, 0 to 127

@emviveros Thanks.

So it appears to have the exact same default range as [moonlib/mknob], meaning it should work as a drop-in replacement. (Another place to check is the object args.)
