EXS 24 Logic Sampler Users Group

Sorry for posting here, but have you seen the "logic-users" list?  
It's a bit crowded and I like this list because everyone is so easy 
going and I always get several replies.

I'm looking at the Tascam FW-1884 which is their Firewire control 
surface with 8 analog ins/outs, 8-channel ADAT, and more.  One nice 
thing about this unit is that it has inserts for each analog 
channel.  When reading the literature it explains that you can 
monitor directly on the board for "zero latency monitoring".  I'm not 
all that technical, but I'll assume this means you monitor everything 
coming into the Tascam before Logic ever processes anything.  I 
believe Pro Tools LE (Digi 002/002R) has this feature too.  

My question is in regards to monitoring audio AFTER Logic processes 
it.  I suppose this isn't specific to the Tascam and could be 
relevent to any soundcard, but is it possible to hook up a Mic to 
Input 1 of an audio card and (real-time) monitor a vocal based on the 
audio coming back out of Logic?  Or would that put too much Latency 
on what I'm hearing versus when the singer is singing?  I'm asking 
because I wanted to hear the vocal Wet while they are singing but 
unless I use Logic Platinum Verb I won't have that option.  

In a typical studio environment do you monitor all vocals completely 
dry and then add all effects later? 

I know this topic is veering off from EXS24 but I do appreciate 
everyones help.

Regards,
Mark
