That's great!
Will try it as soon as the OSX binaries are available.

I'll add the new web interface for Deken:
https://deken.puredata.info/

I didn't really use it yet, but it might be helpful for finding externals and libraries.

Was curious to know if someone attempted to recreate these weird one-liner symphonies in Pd. It should be possible right? Is there any bitwise math genius able to understand this?

t*(((t>>12)|(t>>8))&(63&(t>>4))));

There is a nice write up here and a funny JS toy to play with.

A bit OT and not exactly elegant, but if you need a general solution that also works with floats:

It's the only way I know to see whether an argument (symbol or float) has been provided or not. It takes advantage of a string escape bug, credit goes to the Pd list.

This is usually my approach:

Curious to know if there are simpler ways of doing it.

Well, if you want to simplify the patch you could also just use a creation argument for [moses] instead of the loadbang message.

THANKS

btw, another option is to use the tglgrid external https://github.com/nicklan/tglgrid. You'd have to have a route after the [tglgrid] that routes depending on if you're saving or playing.

That looks interesting, is there a binary available for OSX?
I can't find it on Github or Deken.

There is a bit of debate around this lately but I would suggest to try Ofelia. You just find it on Deken and the webcam support is great.
GEM is very robust and offers a great user experience, but Ofelia saves you a lot of time when it comes to video formats, streaming and images.

Thanks everyone!

I ended up using this solution:

The user won't be able to change value if the range is fixed.
