I’m having a strange problem with Cubase 6.5, 64 bit. What happens is that i start a new project, load up any drum sampler in the VST rack, and at first it plays fine, and nice and tight, then after a little while (anything from 15 minutes to a couple of hours) there is a latency lag when i try to play in any midi notes.
I have a M Audio Delta 2496 PCi soundcard, and the buffer settings are set to 256, and the latency shows up in Cubase at around 6ms. When it goes wrong, the settings still shows 6ms, but in reality it is more like 40ms, which is hard to work with for finishing off drum loops, or playing in any kind of midi notes live. I upgraded from Cubase 6 to 6.5, bought Novation Focusrite VRM and a Novation Impulse 25 keyboard around the time that it started to go wrong. I have tried different combinations of the three, sometimes uninstalling stuff and have even used my old keyboard but it did n’t make any difference.
Things i have tried include…
a System Restore in Windows
re-installing Cubase 6 without the update
re-installing Cubase 6 with the update
re-installing Cubase 6 with 5.1 update
re-installing Novation Focusrite VRM
uninstalling but not re-installing Novation Focusrite VRM
re-installing Novation Focusrite Impulse 25 Keyboard and Automap software
updating soundcard drivers to the latest drivers
updating soundcard drivers to the one before the latest drivers
updating graphic card drivers
uninstalling and re-installing graphic card drivers
using Groove Agent One drum sampler
using Geist drum sampler
using Poise drum sampler
putting the PCi soundcard in a new slot
doing a repair install of Windows 7
starting a completely new project
trying different settings with Time stamp etc…
and the same thing happens time and time again, without fail.
As you can imagine i am all out of ideas, other than doing a full re-install or buying a newer soundcard. I am prepared to do these at a push, but they have the obvious negatives of time and money respectively, and at the moment i’m not feeling that confident that any of these would work.
I was wondering if anyone has had similar problems to this after either upgrading Cubase from 6 to 6.5 or buying Novation Focusrite equipment, or if anybody has any other suggestions before i take the plunge and try the full re-install or new soundcard route.
Thanks in advance for any help or advice
