I have Logic 5.5 OSX on a Powerbook and would like to set it up as a Virtual Sampler (Not a Sequencer)

In other words I like the EXS24 and it would be a good idea to be able to use it like a GigaStudio from my main Sequencer DP 3.1.

Does anyone know how do set this up or if it is possible? There is no problem sending Midi data to Logic but all I get is 1 Channel even if I have 8 EXS 24s mapped out in the Environment each on a separate midi channel.

So it seems that Logic EXS24 can only operate within the Logic Sequencer as a multi timbral device? Thanx for any input on this.
