I recently purchased the Arturia V package version 4. I am experiencing this issue with Analog Lab, and -only- analog lab. All other synths work fine, and are set to ASIO/Delta1010/64 sample buffer size.
Analog Lab changes the buffer size to 2048 samples, and as long as Analog Lab is running, I can not change it back. This does cause an appreciable delay from when a key is pressed and sound comes out.
I am using Build 126.96.36.199,build 18. My system is an ASUS P8-Z77-VPRO motherboard with an Intel I7 (I3770K) quad core CPU running at 3.5 GHZ. I have 32 GB of RAM in the system, and my primary drive is a Samsung SSD. (500GB with 130GB used)
Since I use the synthesizers in Cubase (and not Analog lab), this is not an issue as far as the synths go. (VST or Standalone)
Thanks for taking the time to read this.
Warmest Regards and happy holidays
