This is a known problem with Logic - you can't simply play a whole 
bunch of VSTi's in realtime.
But...............there's a great workaround that appeared on 
Logic-users. Here it is:

MACINTOSH
1) Create a MIDI Instrument in the Environment, and cable it to all the
Audio Instruments you want to play simultaneously.

2) Insert the I/O Plugin on each Audio Instrument _EXCEPT_ the first Audio
Instrument.  Set an Input and Output on each I/O Plugin, then bypass the
plugin.

3) Select the MIDI Instrument in the Arrange, and hit Play or Record and
play your multiple softsynths in  realtime!

WINDOWS
1) The same instructions as above, except for #2 above you need to place the
I/O Plugin on ALL Audio Instruments, including the first one.

This procedure also allow you to change AI tracks while playing without any
audio glitches or cutouts.  If you want to get deeper into the environment,
you can create splits, layers, etc. with transformers and channel splitters.

There are a couple of catches:
* Logic must be in Play or Record for this to work.  If you're looking for
non-stop performance, just running Logic in a short cycle will do the trick.
* Keeping synths "live" like this has a heavier CPU load than simply normal
playback, so be forewarned.
