Hello Spark users,
For those of you having cpu problems with Spark for Windows, there is a debug version of the VST plug-in and of the stand-alone that you can download here:http://www.arturia.com/downloads/spark/beta/Spark_With_Cpu_Log.zip
The zip archive contains both 32 and 64 bit versions, and a readme detailing how to use them as well. These binaries include the features of the version 1.6.1 + a CPU logger which will generate files containing numerous cpu measurement.
Thanks to every one willing to help.
