Hi Group,

           Does anyone have any problem in playng back from Logic PLT 
all
           togheter  
           this softsynths: Reaktor / Bitheadz AS-1 / Emagic EXS24 
sampler and 
           Emagic ES1 Synth?

           EG Recording 4 different midi tracks for each synth and
have 
them 
           playng back all togheter.

           A dealer today told me that is not possible to playback
all 
the
           Synths 
           in the some time. Is that true?
