The Logic Off Topic list

I am running on MAC OS 9.2 with 
ESBTDM is running in demo mode... I initiated DTDM in the audio
hardware & drivers menu... as far as I understand it, audio
tracks/instruments' signals assigned to DTDM should be sent to my
digidesign interface outputs... however, I have not been able to
achieve this at all... I assign an audio instrument, say, evp-88, to
DTDM... play in the part... NO audio output from my 96 I/O... NO
signal indicated on the meters within the logic mixer... same happens
if I import an audio file into a track assigned to DTDM... NO audio
output from my 96 I/O... NO signal indicated on the meters within the
logic mixer...what am I missing here??? please get me some help, as I
have obviously misunderstood how the thing is supposed to work, or
have not set it up properly?? it seems a really simple thing, but it's
just NOT WORKING...system is as follows:
