I'll try again. Hello all, I've have a project where I used patterns from the session drummer for my drum track, and bass and piano tracks using the TTS. I was in the middle of recording the piano track while playing back the drums and bass tracks when the piano and bass tracks just froze. The drum track continued to play but while pressing the keys I could get no sound and the bass track also stopped playing. I previously noticed a lagging at times as I played and or recorded on the piano track. I'm using CT 6.2 with the update, Sonar 6 Producer, JFW 8.0. I have connected to the PC, a 1212 Mackey mixer, delta 1010 sound card, a midi sport 4x. Any help would be appreciated. Thanks
