Hiya TC,..... Have you checked out the FAQ's on the digi001 homepage? What you are trying to do is explained in these notes. Nevathaless,........... First thing to do is set up your OMS studio setup. This may seem to be a bit of a mission at first, but the help files are very good and should get you off the ground. You need to define the drum machine you are using, the channels it can send/recieve midi data on and your midi cable configuration then you are ready to move on. In PTle you need to create a new aux input track, and set it's inputs to those your have your drum machine plugged into on the 001. Now create a new midi track and assign it's midi channel to one of those set up in OMS for your drum machine. Place your recorded midi regions/tracks onto this midi track and you should hear them. Remember to push the faders up !!! You may want to record those midi tracks into audio at a later stage,......... Check out those FAQ's Good luck //NW
