Having gotten sick of the lack of instrument sounds that really grab me with Logic Pro's built-in instruments, I bought Toontrack's EZKeys 2 and the Dark Industrial and Vintage Vibes expansions for it, and oh man I am having so much fun right now. 😁 The Vintage Vibes expansion is a recording/recreation of a Wurlitzer electric piano and it sounds amazing, I've got a bluesy swing thing going on that's such fun to play bass along with.
