How do I use plugins such as massive in Logic pro X ?

Are you saying you purchased all those programs and don't know how to use them, and you purchased Logic and don't have a clue how to use plugins??

Please explain.

if they're not showing up in Logic you need to be sure you're using the 64-bit versions as only 64-bit plugins are supported.

I can see the massive.component file, and reaktor.component file in the plugins folder but i don't know how to open them in Logic X.

I'm sorry if I didn't make myself clear.

No sense in all of us other users rewriting the manual here, Logic is deep, go here and take a look around.

In the Channel Strip, for the instrument (it will look like a blue button -- the *first* down from the Setting button), click on the right edge (it's a disclosure triangle when you mouse over it) and in the dropdown, follow > AU Instruments > Native Instruments > Reaktor (or other) > Stereo (or whatever audio out you need.)

From the mixer, for each channel, there is an "Input" line where the instruments are located - same blue rectangle as in the channel strip - same way to set the instrument:

The instrument button is a "3-way switch" - on the left edge is a "power" icon (you can turn it on an off from that) - the middle is access to the instrument controls (dialog) - the right is the selector menu.

All Native Instruments synths are 64-bit compatible. If Logic loaded it - it will be there. If it's not there, go to the Audio Units Manager and rescan.
