I am getting a little frustrated with LSP. When I play back my sequence it is not displaying properly. It jumps and missess bits. When I watch the Flashing on each channel in the sequencer it is skipping and missing. It is now so bad that i can't programme properly. I have a quad core 3.6 Ghz i7 with 8 gig ram. Whilst playing it is only using 4 gig of ram and only 15% of the cpu. The audio file is mp3, 128kbs 44,100khz. I only have 2000 channels. The only thing I can think of is my show is 12.30 minutes long. So the audio track is this long (mixed 9 songs ) I like having one sound track so there is no gaps and so music flows. This issue has started when I got upto the 6 minute mark in the programming. Is this the likely cause? What is the gap between songs like if done individually? I have re-installed windows 7 as well. Would more ram help or fix the problem?
