Hi
Unfortunately the MPC Ren VST plugin is still completely unusable for me in my DAW. Here are my system specs:
CPU: i7 2600K
GPU: Radeon HD 6970
RME HDSPe PCIe firmware rev 20
RME Hamerfall ASIO driver 332
OS: Windows 7 x64
MPC Software 1.3.0
Cubase 7.0.2 x64
The standalone version of the MPC software seems to function as expected, but if I try and use the MPC VST plugin within my DAW (which is essentially the only way I want to use this MPC) then first the MPC plugin will crash and eventually VST bridge and Cubase itself will crash.
All I need to do to reproduce this is the following:
1) Create an empty new project in Cubase 7.0.2
2) Add the MPC as a VST instrument
3) Open the MPC VST and browse to samples
4) Start adding samples to pads by dragging them over
Then eventually (usually after adding only a few samples) the UI of the MPC VST will either go completely white and unresponsive (see screen shot below), or will not update - i.e. you cannot manipulate anything within the MPC's VST UI - you cannot select different samples or manipulate any of the parameters within the UI:

When this happens, the instance of the MPC VST loaded will never return to normal, even if I close and re-open it it will remain in this 'crashed' state. Sometimes I am able to disable the VST completely and reload another instance of the MPC VST, but it will crash in the same way as soon as I repeat the above.
The problem also occurs if I simply try and load previously saved MPC presets in the VST version within my DAW that were created in the standalone version of the MPC software. Sometimes I will get a more serious crash with VST Bridge that is caused by the MPC.dll. This crash seems to seriously affect VST Bridge as the process completely hangs and even after Cubase crashes, I have to force the actual process to quit. When this happens I get the following error:

I was really looking forward to version 1.3 as I was hoping to finally be able to use my new MPC Ren, but it seems there are still fundamental problems with the VST in my scenario. Any ideas or suggestions greatly appreciated.
Cheers
Edit: BTW, contrary to another post in this thread, I am able to adjust the size of my MPC VST window in Cubase 7 just fine before it crashes.
