I am very new to Max. This is pretty much my first patch that does anything more than simple MIDIOSC conversions.

This is also my first post. Hi! I'm a UX/Visual designer excited about Jitter.

I've worked my way through most of the basic Max tuts, and decided to start working on some of my own tools to exercise what i've learned. Im working on a complete RGB/CMY/HSL bin/8bit/hex color picker that is nearly finished, with the exception of updating the HSL controls. Evidently the Swatch object receives HSL but does not output it?

My issue is within a RGB2HSL subpatch based off the formula found at 

http://www.easyrgb.com/index.php?X=MATH&H=18#text18

It was going very well until the last last few "else if" statements, which are in the middle left section of the "chromatic" subpatch. I quickly discovered that "else if" is not allowed, and I couldnt get a text "or" or double pipes working either. I broke them in to separate if statements, but I believe im now suffering a race condition. In addition, id like to refactor that and the Saturation sections to only evaluate the expressions if their conditions are met.

About "else if": use [if «condition» «true-result» else out2 «false-result»] and connect the right outlet to a second [if] object that does your "else-if" logic.

But you might find life altogether easier with [jit.hsl2rgb] and [jit.rgb2hsl].

Ah, thanks! Thats quite simple and obvious. I had forgotten about the ability to output on a different connection.

While this works, id still love or/|| support.

If you really want to do a lot of stuff with if/then/else, for loops, etc., check out mxj, js, et alii which give you access to all of those traditional programming idioms. You can pretty quickly drop that code into js (javascript), and it's going to work great.

In Max, it's more idiomatic to control flow via gate, switch, router, route, etc. Also, be sure to check out the vexpr object, especially with the @scalarmode 1 attribute. It does math on lists and can often simplify things.

Thanks for the suggestions. Much of this was just an effort to exercise what i've been learning, which is why I avoided using JS. Perhaps reworking the if than logic to a more dataflow oriented approach would be a good exercise as well.
