If I multiclass a Magus and a Sorcerer in Pathfinder, how do my casting mechanics end up? Do I get a certain amount of slots that I must prepare in advance in addition to a few I can improvise with, or do they all become either prepared or improvised? Do my spell lists stay separate for the different slots, or can they cross over between caster lists?

    \$\begingroup\$ If you want to play a spontaneous casting magus there is now an archetype for that in the Advanced Class Guide. \$\endgroup\$

You retain the casting mechanics of both classes separately.

If you were a multiclassed 4th-level character, for example, a Magus 2/Sorcerer 2, you would have all the class abilities of the level you reached in each class, for instance a 2nd-level Magus and a 2nd-level Sorcerer. Their spell lists do not mix; you will have to prepare your Magus spells as if a 2nd-level Magus, and your known Sorcerer spells, numbering as many as a 2nd-level Sorcerer would know, can only be cast from the slots that a 2nd-level Sorcerer would have, and would suffer arcane spell failure chance appropriate for the armor you wear.

    \$\begingroup\$ Also, you maintain separate caster levels for the two classes. And of course, this whole system heavily discourages playing a PC with multiple casting classes. \$\endgroup\$
