Sonar X2 question... not sure if this is the right place, if not please point me. Trying to bounce several clips in the same track together into one clip. For some reason they won't bounce. Has not happened before so wondering it there is something underlying the clips preventing them from merging together. These are midi clips.

I'm using Splice sound samples with Sonar x2. After I preview a sample in Splice there is a big delay before the sound on Sonar kicks back in. Sonar actually hangs a bit, unfreezes and then after 1- seconds the sound is back on. Thinking it's something to do with my interface - Presonus Fire Studio - and/or maybe sampling or latency or buffer settings. Anyone experiencing this or know a fix ?
