I"m around page 70 of the Beginner Book. So far I can do most of the basics, record to guitar via mic and sounds good for starters, record bass direct...also sounds great for starters. Hooked up my interface obviously with no problems. Now, I have a PCR midi keyboard which I want to use with EZ drummer. I have it hooked up to my cpu via USB. I'm still getting no sound through my monitors when using EZD by mouseclick, only through the little speakers below the screen which I thought I had turned off. I can drag and drop the beats I choose into Reaper but then I hear nothing when I do a play back. I need to set this up properly. To summarize, I need to be able to trigger my EZD from my keyboard, or other instruments. I want to be able to hook up my PCR-M1 to my GR33 guitar synthesizer to use those sound effects, I have a midi cable handy.
