EXS 24 Logic Sampler Users Group

Interesting information there guys,
  I misunderstood the whole concept - thinking that a "raid" setup
was limited to utilizing expensive SCSI drives only. Stupid me didnt
realise 
the 'I' in RAID meant cheap ATA HD's!!!

In that case then, the $$ needed to set up one of these raids in
conjunction with 
logic using the EXS for big sample librarys like orchestral work
doesnt seem so 
bad at all now :()  
Most likely will do this down the line when i have enough $$ for the
Vienna 
library.

Anyways keep the info-flow coming ..
Cheers

The
