Thanks - I ran Latency Mon whilst playing different patches with Zampler and this was the result - apart from first couple of sections I am afraid I do not know what any of it means so would appreciate advice. I seem to remember when I tried task manager I couldn't look at it whilst in CbB but will try it again
CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
LatencyMon has been analyzing your system for 0:03:28 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: JOE-PC
OS version: Windows 10 , 10.0, build: 18363 (x64)
Hardware: ASUSTeK Computer INC., P8Z68-V LE
CPU: GenuineIntel Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz
Logical processors: 4
Processor groups: 1
RAM: 8172 MB total
_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 3311 MHz
Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.
WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 319.60
Average measured interrupt to process latency (µs): 5.353070
Highest measured interrupt to DPC latency (µs): 313.30
Average measured interrupt to DPC latency (µs): 1.594756

REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: dropbox.exe
Total number of hard pagefaults 3060
Hard pagefault count of hardest hit process: 2644
Number of processes hit: 29
