I'm very new to the Logic Pro 6 software and I'm not getting any sound generated when playing the onboard instruments (Grand Piano). The music notes are showing up in the matrix window that are generated from a Radium 61 Midi Controller so I know it recognises that and I am using MOTU 828 mk2 as my firewire source. Is there a setting somewhere in the Logic program that I just don't see? Some advice would greatly be appreciated. Tom
