Hey, I’m a total newbie to all of this so I’m hoping that you can help me out! I am using EZ Drummer with Toontrack Solo and a Roland TD-9. I thought that I had everything set-up perfect since I was able to play on my TD-9 using a midi-USB cable to my computer out to a Lexicon Alpha audio interface. I have my headphones hooked up to the Alpha. I selected the Alpha as the ASIO audio, midi is checked for the UM-ONE cable and e-drums are selected for controller with CC selected for the VH-11 hi-hat. I was able to use EZ Drummer with TT SOLO as the host for a few days before problems started. After playing for a while I took a break and turned off my TD-9. I came back a little later, turned it back on and there was no communication between the kit and the software. So I shut everything down and restarted my computer. When I opened SOLO my computer immediately froze and my CPU usage shot to 100%. It does that every time I open the software now. I have unistalled and reinstalled SOLO but the same thing continues to happen. My system is not great but good is enough to run EZ Drummer. I’m not doing any recording just playing. My system is an AMD Sempron Processor LE-1300 2.30 GHz, 62-bit, 2 GB RAM and my hard drive shows 150 GB free of 221 GB. I am really stuck!! Chris
