Hey MixedUp,
- when you suggested Camel Audio's Alchemy was that because it has the YMCK type 8-bit sounds out of the box?
No.. The OP asked about that plugin at the same time as they asked about YMCK..
- does Camel Audio's Alchemy add new capabilities/sounds to Logic Pro X that it doesn't already have? i.e. just trying to understand can you do most of what Camel Audio's Alchemy offers anyway in LPX?
Alchemy is a 3rd party Software Synthisizer that can and does produce very unique sounds... Go to Camel Audio's website and listen to some of the demos and you will see what I mean...

- I did note there is http://www.plogue.com/products/chipsounds/ that could be a good option for the retro sounds, but would something like Camel Audio's Alchemy do the same thing plus more (noting it is more expensive)
In my humble opinion, for 'Chipsound' type sounds and FX... Plogue's plug is superb.... Alchemy is a very different sort of Software synth to Plogue's... and while it can produce some chipsound type sounds that is not what it excels at, again, in my opinion.. Alchemy is a very much more versatile softsynth..but then again, Plogue's is not so versatile but extremely good at what it is specifically designed to do..Chipsounds!)
The few times I have needed C64 type FX and sounds, I have used Plogue's plugin to great effect 🙂
Frankly though, to begin with... I would play with LPX (making sure you have downloaded all it's additional content first) and try out it's own built in synths and effects.. You can easily generate a lot of different types of very high quality sounds just using those before venturing out in the world of 3rd party instruments and FX plugins...
Hope this helps...
