Thanks for the welcome.

I checked with the performance meter and it showed all cores at or around 8% and memory usage around 32%

Kind regards,

System is as follows:-

CPU = AMD A6-3650 2.60Ghz APU (Accelerated Processing Unit) Quad Core with on-chip Radeon GFX using shared memory.

System RAM = 8Gb
HDD = 1Tb

OS = Windows 7 Home Premium X64

Internal Realtek HD sound

I have no problem with Cakewalk Sonar 8 recording midi pitch bend, Cakewalk records with no jittery at all, and when using Linux (dual boot Ubuntu/Win7) Rosegarden, midi pitch bend is also really smooth, re-viewing or recording, but it's only BiaB that has the problems recording midi pitch bend, I have tried every which way in changing latency, but no change.

I can't use ASIO4ALL as I have to completely disable windows audo because ASIO says the MS wavetable synth is in use, but disabling win audio means I can't use CoolSoft midi synth.

I have also tried a PCIe soundcard, but there's no way of disabling the onboard sound in the PC BIOS, and BiaB always tries to use the onboard sound, with no options to switch to the PCIe soundcard.

The jittery pitch bend sounds like the pitch bend range in BiaB is set to 0, thus resulting in when the bend data is being received by BiaB, it's range is set to 0 resulting in the bend being bounced back to center position, I had the same problem with a VST synth called 'Toxic Biohazard' and I had to set the bend range to the same as the midi keyboard, but I can'r see where in BiaB to set the incoming bend range to match the keyboard's range.
